Hi all,
I'm trying to have an AdvancedDataGrid using a GroupingCollection
that has a certain number of rows that get grouped by a column called
"GROUP_NAME". I set a Timer() and call a refresh on the XML every 5
seconds or so (it's provided by WebORB through AMF). I want to
remember which rows were closed and which were open BEFORE the
refresh and i want to keep them closed/open AFTER the refresh.
What I've done is:
- created an onClick event for the AdvancedDataGrid
- made it do this:
var item:Object = AdvancedDataGrid(event.currentTarget).selectedItem;
// this is so that the user can click the whole row
if (adg.getParentItem(item) == null) { adg.expandItem(item, !
adg.isItemOpen(item), true); }
closedItems.addItem(item);
// closedItems is an array of "closed" rows, let's not worry about
their current state and so on, I just want to close any row that's in
this array
Then I have an onResult handler for the XML which, when the XML is
read from the WebORB object, runs the following block of code:
if (closedItems.length > 0) {
//Alert.show('some items should be closed');
//Alert.show(adg[1].toString());
for each (var oneRow:Object in closedItems) {
adg.expandItem(oneRow, false);
Alert.show(adg.isItemOpen(oneRow).toString());
}
}
Now, the above Alert.show() returns, CORRECTLY, 'false', i.e. that
the item is CLOSED. However, the actual item in the datagrid is still
folded open!!
My GroupingCollection is defined like this:
<mx:GroupingCollection id="groupedData" source="{agentData}"
childrenField="xx" >
(etc)
I refresh by re-assigning agentData to the WebORB result and calling
groupedData.refresh().
What am I doing wrong? Anybody have any suggestions?
Cheers,
