Hello guys,
I'm trying to filter my ADG without success :
I created a GroupingCollection from a flat ArrayCollection.
ADG's dataProvider is GroupingCollection.
First issue : refresh
if I filter the underlaying ArrayCollection, the related
groupingCollection doesn't refresh automatically (bug? feature?)
Actually I menaged to force gc.refresh() with some event( it is
impossible to listen on CollectionEventKind.REFRESH because of
infinite loop ac.refresh = gc.refresh )
Second issue (more important) : openNodes
Ok now that my gc is refreshed, the Tree in the ADG collapses
itself
(ok let say that is normal), and I need it to expand all nodes
that
were opened before.
I tried to do something like this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
gc.refresh();
myADG.dataProvider.openNodes = openNodes;
and it doesn't works.
next I tried this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
for each( var node : Object in openNodes )
{
IHierarchicalCollectionView( myADG.dataProvider.openNode( node )
}
guess what, doesn't work :)
I'm calling myADG.invalidateList() each time too.
I don't know what to do to achieve this simple task, I'm a bit
disappointed because I expected lot more from the brand new
AdvancedDataGrid and this basic functionality actually seems too
hard
to implement.
I still hope I'm wrong and someone can show me the correct
solution :)
Thank you all,
Adnan

[flexcoders] Re: AdvancedDataGrid itemOpen() to resize Container
I figured out one way to do it:
private function openRow():void{
var windowShade:WindowShade = this as
WindowShade;
windowShade.height += appColl.source.length *
20;
}
The problem seemed to be that I was referencing the parent container
incorrectly. The thing I want to do now on the itemOpen() event of the
AdvancedDataGrid is to get the height of its renderProvider (another
AdvancedDataGrid) and then add that to the overall height.
I've perused the properties available from the AdvancedDataGridEvent but all I
get is access to the current item and an array of renderProviders, not the
height of the renderProvider itself.
Is there a way to get access to the height of an AdvancedDataGrid's
renderProvider?
Thank you.

[flexcoders] Re: AdvancedDataGrid: expandItem()
I believe the answer is to use callLater before acting on the AdvancedDataGrid.
However, the kink is that my dataProvider isn't set until XML is loaded.
Here is the setter for the dataProvider (source of my GroupingCollection):
public function set applications( arr:Array ):void{
_applications = arr;
appColl.source = applications;
callLater( expandRow );
}
..And then here is the expandRow() method:
private function expandRow():void{
// Expand the first row of the ADG
var obj:Object = gc.getRoot();
var temp:Object =
ListCollectionView(obj).getItemAt(0);
grid.expandItem(temp,true);
}
mx:dataProvider
mx:GroupingCollection id=gc source={appColl}
mx:Grouping
mx:GroupingField name=label/
/mx:Grouping
/mx:GroupingCollection
/mx:dataProvider
The error I get when I run this code is this:
Index '0' specified is out of bounds.
I'm just not sure why this might be happening. I mean, I'm using callLater..Any
ideas?

[flexcoders] Re: AdvancedDataGrid/GroupingCollection performance with non-trivial data sets.
--- In flexcoders@yahoogroups.com, dolinja jmdolin...@... wrote: Hi all, I'm starting an evaluation of the AdvancedDataGrid and Flex 3 as whole for my project team which has a large financial application built currently in Flex 2. We were very anxious to apply the AdvancedDataGrid to provide grouping and summing against one of our large DataGrids and have found the performance far too poor to use on anything larger than a trivial dataset. The GroupingCollection's source is an ArrayCollection loaded from an HTTPService. It has 3700 records, each with 20 columns. We've found that we can create the collection with only one GroupingField, with 3 different SummaryFields being summed and the GroupingCollection.refresh() executes on average of 9 seconds. However to really gain buy-in for this feature, we want to group/sum on two different values and thus two GroupingFields, each with the same SummaryRow and SummaryFields. In this case performance drops to an average 123 seconds for GroupingCollection.refresh(). Completely unusable especially as we get a Flex timeout in the browser after 15 seconds. One more bit of information is that in cutting the size of each record down to 5 columns instead of 20, the refresh() only averages 8 seconds even with 2 GroupingFields (and still the 3700 rows!). Something is very wrong here as grouping/summing should really depend upon the number of entries in the ArrayCollection, NOT the number of fields in each entry in the ArrayCollection. Finally, this functionality only seems to work with object as the result format for the HTTPService. If I use e4x (as all of the existing services in our application do), wrap the XMLList returned as an XMLListCollection to use as the GroupingCollection's source, even with just one GroupingField it averages 98 seconds. I'm going to start digging into the GroupingCollection source, but I'm not optimistic. Does anyone have tips or hints as to anything that can help optimize this process? Or any further info from Adobe about known performance issues with AdvancedDataGrid/GroupingCollection? Thanks so much, any help is greatly appreciated! Regards, Jason Have there been any improvements made to GroupingCollection performance since this posting?

RE: [flexcoders] Re: AdvancedDatagrid
Use : event.currentTarget.selectedItem;
That will return a reference to the currently selected item object in the
dataProvider.
Alternatively, you could do:
ArrayResults.getItemAt(event.CurrentTarget.selectedIndex)

[flexcoders] Re: AdvancedDatagrid static row for totals.
Sadly it's wishful thinking. I accomplished it by adding a totals row to my data provider and then performed custom sorts in order to keep the totals line always at the bottom. Since the sort compare function doesn't pass in the column you have to maintain a reference of what kind of sort (ascending/descending) and which column is being sorted. Sadly an NDA prevents me from copy/pasting the code I have but I hope to write up a nice rant soon about it, complete with example code. It really is a pain. Here's hoping for a better ADG in gumbo.

--- In flexcoders@yahoogroups.com, muruga murugave...@... wrote: Hi I have advanceddatagrid in which i am displaying the data in Tree structure. Since the data is huge and it is taking lots of time to retrieve from databse, we wanted build the tree dynamically. Means initially we want to display the tree only will the parent nodes. Only when the user expands the parent node, we need to build the children node of this parent node (only when the user expands the parent node, we go to DB and retrieve the children node details). Is it possible to do this with FLEX advanceddatagrid tree structure. First i would like to know, is it feasible to do? if yes, then how to do it. It is very urgent. I've done this, not with an AdvancedDatagrid, but with a HierarchicalCollectionView, which is what an ADG dataProvider is. Essentially, I called a service that gave me the top level of the hierarchy. The objects that populate the HierarchicalCollectionView each have a method that loads the children. I don't wait for the user to open the nodes. Instead, I start loading the children in the background by calling this method as soon as the top level is known. The child object will generate an event when its children are loaded, and then the parent class (which has the HierarchichalCollectionView as a property) will call the next child in the line. If a user selects a child that has not loaded its children yet, when the event fires that says the last child was loaded, I interrupt the predictive load to load that one. This has been discussed recently on here, and I think the person who was doing this type of load on a Tree control had to do something once the load was complete to tell the node to open. HTH; Amy

[flexcoders] Re: AdvancedDataGrid update problems
I finally managed to reproduce the bug (or one of the bugs). By scrolling to the very bottom and sorting according to any column, it seems to sort, but the last items seen in the grid shouldn't be last. Turns out the grid just hasn't updated the view properly or too early somehow. A delayed call to invalidateList after sorting seems at first to fix this, but it's possible to get the grid into an invalid state despite this. Dispatching a reset event seemed better. Would be nice to figure out the cause since this bandage solution hurts my eyes. --- In flexcoders@yahoogroups.com, kallebertell [EMAIL PROTECTED] wrote: I'll speculate openly in case someone picks up on this.

I'm glad I ran across this post it really helped me with my current
project. I am having another problem that I had hoped this would fix
but it didn't so I figured this was a good place to ask.
My AdvancedDataGrid with a summaryRow will only sort any column once.
If I try to sort the same column a second time it seems to freeze the
sorting on that column and the rest. The arrow changes, showing
ascending/descending but the data remains in the same order. Can
anyone see a problem with this code, or maybe have run into the same

[flexcoders] Re: AdvancedDataGrid - help displaying custom data objects
so to get things to show up as I wanted I had to add a children
property to my EmployeeGroup (didn't see that anywhere in the
documentation, but I noticed the Adobe examples have children
properties).
So I added this in the EmployeeGroup:
pre
public function get children():ArrayCollection {
var kids:ArrayCollection = new ArrayCollection();
for (var i:int=0; i groups.length; i++) {
kids.addItem(groups[i]);
}
for (var i:int=0; i employees.length; i++) {
kids.addItem(employees[i]);
}
return kids;
}
/pre
Obviously it can be more efficient, but it works..which is the start!

From the Help:
A renderer can span multiple columns. In the following example, you
create a renderer that spans two columns:
mx:AdvancedDataGrid
mx:columns
mx:AdvancedDataGridColumn dataField=Region/
mx:AdvancedDataGridColumn dataField=Territory_Rep
headerText=Territory Rep/
mx:AdvancedDataGridColumn id=actCol dataField=Actual/

The problem is with the last two rows in the dataprovider. ADG forces
all of them to be at the same depth and adds 'Not Available' tree
nodes instead of placing the rows without the open/close icons at the
top level. Is it
possible to disable grouping when not necessary? This is a common
requirement and I believe there should be a way to get this working.

[flexcoders] Re: AdvancedDataGrid scrolling
Hi, The only way to get smooth scrolling, with any of the list based components, is to place them in a container (like canvas) and set the list's height explicitly; to render all of the items (valueCommit=myList.height = myList.measureHeightOfItems). This will give you a performance hit, but the scroll will be more natural. This however, will negate the ability to scrollToIndex. -TH --- In flexcoders@yahoogroups.com, michal.sustr [EMAIL PROTECTED] wrote: Hi, is there a way how to enable AdvancedDataGrid scrolling not on rows, but on parts of rows?

[flexcoders] Re: AdvancedDataGrid ItemRenderer
Tracy,
Is it because creationComplete only happens once per visible row and the
renderer is recycled on dg scroll, change, etc?
What I desperately want to learn is how to know when to override a
super's function - in this case updateDisplayList(). How would you know
to do that verses invalidateList() or invalidateDisplayList()??
Is this learned by experience (such as how I am right now), or does one
look at this code and intuitively know to override updateDisplayList?
Does it become more apparent when you start disecting inherited classes?
How is this learned?
BTW, your input helped me arrive at a very elegant solution with native
mxml - AdvancedDataGridRendererProvider:
mx:AdvancedDataGrid ...
mx:columns
mx:AdvancedDataGridColumn headerText=Archive dataField=@archived
width=50 id=archived_col /
mx:AdvancedDataGridColumn ... /
/mx:columns
mx:rendererProviders
mx:AdvancedDataGridRendererProvider column={archiveed_col}
depth=2 renderer=renderers.CheckBoxItemRendererProvider/
/mx:rendererProviders
/mx:AdvancedDataGrid
The depth is the key - where 1 would be the Group node and 2 would be
the first indentation or sub-set of data under the grouping.
Even though I found a solution, I am still very interested in your
thoughts on the learning approach query above.
Thanks to all,
Jeff

I'm having some weird issues with ADG that seem to be somehow focus
related. In some cases ADG will open editor for the last edited cell
even though the editing has been stopped earlier.
This can be reproduced in the example program (which can be found from
the end of this message) by following these steps:
1. Open Southwest - Nevada.
2. Click Estimate column for the Bethany Pittman row to start editing.
3. Cancel edit by pressing ESC.
4. Select Northern California.
5. Select Submenu from Menu.
What's happening here is that after clicking submenu, an editor will
open for the cell that was edited in step 2 and that row becomes
selected again. This seems to happen with Opera, Firefox and IE.
There is also another similar issue that seems to exist only for
Firefox and Opera:
1. Follow steps 1-4 from the previous example.
2. Change to some other program window.
3. Go back to the browser.
4. Click anywhere in the table.
Again, editor for the last edited cell will open where ever you click.
Is there something I'm missing here or is this a bug in ADG?

Fwd: [flexcoders] Re: AdvancedDataGrid preserve openItems after data update
OK here's what i did to keep my nodes open.
un my update function i call preventDefault() to stop the expected operations.
then i manually build using updated data my object instances
then search the original objects till i find my matching object
overwrite the orginial object with the new instance
then run a refresh() on the dataprovider.
This appears to be working for me and it is having the expected
results.so far :)

First, I got a nice array of objects containing the 'nodes' for the

The final step was to iterate through all the nodes, find out which

This is where I ran into problems. When I tried to re-open a node

(ok let say that is normal), and I need it to expand all nodes that
were opened before.
I tried to do something like this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
gc.refresh();
myADG.dataProvider.openNodes = openNodes;
and it doesn't works.
next I tried this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
for each( var node : Object in openNodes )
{
IHierarchicalCollectionView( myADG.dataProvider.openNode( node )
}
guess what, doesn't work :)
I'm calling myADG.invalidateList() each time too.
I don't know what to do to achieve this simple task, I'm a bit
disappointed because I expected lot more from the brand new
AdvancedDataGrid and this basic functionality actually seems too
hard
to implement.
I still hope I'm wrong and someone can show me the correct

[flexcoders] Re: AdvancedDataGrid - Changing the background color on a row.
Hi,
I just need to set the Background color of the First Row to a
specific color and the rest of the rows can have the default background.
And the data for the grid is set using the dataProvider (
ArrayCollection) is set at runtime.
So i don't want this Item Renderer for each and every row.
Is there a simple way to do this..
I couldn't find a method to check the columnNumber from the passed
AdvancedDataGridColumn Object !!!
I have this method to set the style as per sreeni code..
private function setRowStyle(data:Object,
col:AdvancedDataGridColumn):Object{
// I need to check if the column is 0 and it
has a specific
value..(To determine this is the first row..)
if (col.){
return { rowColor:0xFF,
fontWeight:bold };
}
return {};
}
Thanks

[flexcoders] Re: AdvancedDataGrid - selecting a cell
In fact, it is even simplier. The grid comes with an empty record. Moving a mouse over second column I have noticed that a mouse pointer will change to mouse arrow from the middle of the column while moving to the right. And it will be staying like this over second column as well. Moving mouse to the left over being second column will change mouse pointer into the vertical. --- In flexcoders@yahoogroups.com, markgoldin_2000 [EMAIL PROTECTED] wrote: I am having a problem with ADG.

Oh, I fully understand why it's a problem with how they've decided to

standard on every other grid component out there. Who knows, maybe in Flex

Re: [flexcoders] Re: AdvancedDataGrid ItemRenderer

there is an easier way to find the item i'd sure like to know...
public function handleDragOver(event:DragEvent):void
{
var dropTargetItem:Object = null;
var
dropTarget:AdvancedDataGrid=AdvancedDataGrid(event.currentTarget);
var dropIndex:int = dropTarget.calculateDropIndex(event);
// Get drop target.
var view:ICollectionView =
ICollectionView(loadOutsGrid.dataProvider);
if(dropIndex view.length)
{
var cursor:IViewCursor = view.createCursor();
var x:int = 0;
while(cursor.afterLast == false x dropIndex)
{
cursor.moveNext();
x++;
}
if(cursor.afterLast == false)
{
dropTargetItem = cursor.current;
}
}

Hi Alex,
If it were only that simple... As I said earlier, the change event
is not fired (in the ADG) when a user arrows off the header. If I am
tracing the movement of the selected cell around the ADG, I miss a
cell when the user arrows up too far, i.e. to the header, and then
arrows down. Give the case below to see what I mean (xml file at
http://www.talonrisk.com/apps/test/data.xml

Should the change event be fired here? Is this a bug? If not, is
there an event that IS fired in this case?

I'm looking to:
I have an AdvancedDataGrid and I want track the user paging up,
down,
and across the grid with the arrow keys. I don't want the data to be
editable, which means I cannot use the itemFocusIn event (throw, as
you say, by the item editor).
So I would like to know when the user scrolls through a datagrid
(preferably an ADG) using the arrow keys. I do NOT want the data to
be editable. The itemFocusIn event does not fire, and the change
event does not produce acceptable results.
I think the answer to the question, is No this is NOT possible out
of the box. You have to write a renderer that implements
IFocusManager and use the itemFocusIn event

[flexcoders] Re: AdvancedDataGrid - how to clear contents?
Hi Greg, Thanks for the reply! I've figured out the way how to clear the contents. I was unable to do it if ADG and group collection and dataprovider were in MXML format. So, I just created independent ArrayCollection, binded it to the GroupCollection as source and then after getting query result from server manually inserted objects from HTTPService into the ArrayCollection. And before fetching the data simply call arrayCollection.removeAll(); After debugging the code I would say that the you can't clear the contents assigning null to the data provider as code checks everywhere if source != null and in this case just doing nothing. O the contrary, if you generate CollectionChanged event everything is fine. PS I am still wondering how direct binding HttpService ADG works for most of the people - for example when result is just only one object XML parser does not generate vector representation of data. Anyhow, I am avoiding MXML as much as possible. Cheers, Dmitri. --- In flexcoders@yahoogroups.com, Mr Greg Murnock [EMAIL PROTECTED] wrote: Are you sure there isn't another datProvider set somewhere?

The result I saw was a raw BTung Chau/B instead of the
bold
text
format I want.
Please help.

[flexcoders] Re: AdvancedDataGrid::toolTip formatting
The same thing for groupLabelFunction. Returned HTML text is not
accepted.

Hi Tung,
you can use the trick mentioned here

to display html formatted strings as toolTips.

[flexcoders] Re: advancedDataGrid drag over column calculating wrong index
If you drop the item with the mouse over the top half of the first item it becomes the first item. If you move the mouse over the column header it becomes the last item. It is the same behavior even with simple List.

[flexcoders] Re: AdvancedDataGrid and setItemAt()
Thanks! getItemIndex works not indexOf. But still I have one problem. i have ADG and arraycollection where all data is. Arraycollection have ordernumber, orderline, product etc. data. And i have grouped lines by ordernumber. If i edit line it moves to last. Is there possible to sort data by ordernumber and after that by orderline -number? of course if user click header sorting change, but at default it sort by ordernumber, orderline. Thanks for helping! --- In flexcoders@yahoogroups.com, Paul Dale [EMAIL PROTECTED] wrote: The selectedIndex is the index of the row in the visual object, which might not be the same as the index of the item in the data provider. You can use data.setItemAt(adg.selectedItem,data.indexOf(adg.selectedItem)).
Re: [flexcoders] Re: AdvancedDataGrid and setItemAt()
You need to set the ArrayCollection.sort property... have a look at mx.collections.Sort and mx.collections.SortField. There are examples on this page http://livedocs.adobe.com/flex/2/langref/mx/collections/Sort.html that show how you can create a Sort with multiple SortFields. hth Scott Scott Melby Founder, Fast Lane Software LLC http://www.fastlanesw.com monkeeeh wrote: Thanks! getItemIndex works not indexOf.

[flexcoders] Re: AdvancedDataGrid and setItemAt()
With normal DataGrid setItemAt this works.
