ICollectionView or a filterFuncton can work for this; if you don't want to mess with the underlying source. -TH --- In flexcoders@yahoogroups.com, "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Well, you "hide" a row by removing it from the dataProvider.

Not sure how well filters work on HierarchicalData. HTH; Amy
[flexcoders] Re: Hiding a row in an AdvancedDataGrid
When I try this, the filter function isn't called for top-level items. It's called for all child nodes in the dataProvider, but not for the parent node. Any idea why this might be, or do you need a code sample? --- In flexcoders@yahoogroups.com, "Tim Hoff" <[EMAIL PROTECTED]> wrote: > > > ICollectionView or a filterFuncton can work for this; if you don't want > to mess with the underlying source. > > -TH > > --- In flexcoders@yahoogroups.com, "Tracy Spratt" wrote: > > > > Well, you "hide" a row by removing it from the dataProvider.

Interesting, I would think that the opposite would occur; if you're using something like: return item.myfield=="whatever";. Sure, post your filterFunction; as well as a basic idea of the collection's structure. -TH --- In flexcoders@yahoogroups.com, "whatabrain" <[EMAIL PROTECTED]> wrote: > > When I try this, the filter function isn't called for top-level > items.

[flexcoders] Re: Hiding a row in an AdvancedDataGrid
My filter function is really simple. Something along these lines:
private function filterFunc(item:Object):Boolean
{
return item is ChildObj;
}
The dataProvider is an ArrayCollection containing ParentObjs.
ParentObj extends ArrayCollection, and contains ChildObjs.
I call ArrayCollection.addItem() to add either ParentObj or ChildObj
to the tree, and both are called after the filter is defined. In
fact, I call the ChildObj insert right after the ParentObj insert.
Basically, I want to hide all top-level nodes in the tree, but the
filter function isn't even called for those nodes.

"and both are called after the filter is defined"
Are you calling ArrayCollection.refresh() after you finish adding the
parent and children objects?

[flexcoders] Re: Hiding a row in an AdvancedDataGrid
No, I never call refresh(). Here's the sequence:
1) Set the filter function.
2) Add a parent object [filter function is not called]
3) Add a child object [filter function IS called]
I've tried adding parents and children later on too, and the filter
function is still only called for children.

[flexcoders] Re: Hiding a row in an AdvancedDataGrid
Anytime that you use a filterFunction or sort on an ArrayCollection,
it won't be executed until you use call the refresh method.
Basically you're saying, ok filter and sort my collection now. It
doesn't happen automatically. After #3, and anytime that items are
added/changed/removed in the collection, execute the refresh method
to re-filter/sort the collection. I'm not sure if this is going to
solve your problem, because filtering the parent objects will
probably take out the children as well. You may have to just create
a new collection, from the original (excluding the parents), and use
that as the DataProvider. But, give refresh a try first.

[flexcoders] Re: Hiding a row in an AdvancedDataGrid
Calling refresh() did nothing.
Note that if I choose to filter out all the child nodes, it works
perfectly. It's only the parent nodes I can't filter, because the
filter is never called for them.

[flexcoders] Re: Hiding a row in an AdvancedDataGrid
You know that the filterFunction is being called because you have a
breakpoint and trace insde it and are running in debug mode right?
Also, is the filterFunction on the correct ArrayCollection (the main one
and not the extended one)? The correct order would be:
1.) Add parent object to main ArrayCollection
2.) Add children objects to the parent ArrayCollection
3.) Repeat 1 & 2 for all parents and children
4.) Set filterFunction for main ArrayCollection
5.) Execute refresh() on main ArrayCollection
That's about all that I have; without poking through the code.

I've cast HierarchcialData to HierarchicalCollectionView in the past for other reasons ( http://flexdiary.blogspot.com/2008/07/musings-on-advanceddatagrid-part- 5_03.html ), but I am not sure if this would work for you if you're not using HierarchicalCollectionView already. If you're using a GroupingCollection, it could also potentially be cast in that way. HTH; Amy
[flexcoders] Re: Hiding a row in an AdvancedDataGrid
It turns out that filtering out the parent node hides all the children too, so I guess this isn't what I want after all. --- In flexcoders@yahoogroups.com, "Amy" <[EMAIL PROTECTED]> wrote: > > --- In flexcoders@yahoogroups.com, "whatabrain" wrote: > > > > Calling refresh() did nothing. > > > > Note that if I choose to filter out all the child nodes, it works > > perfectly.

Doh! Filter, yes. I mostly do e4x, filters don't come instantly to my mind. Thanks, Tim!
