I want my ComboBox itemRenderer to be disabled based on a "disabledFlag"
property in the dataProviderItem.
I have a CheckBox renderer in another column that updates that property.
The ComboBox renderers display fine on initialize, with the correct rows
disabled
But when I click the checkbox, even though the code in the CBO
renderer's set data() and commitProperties runs correctly and sets the
Combobox enabled property correctly, the ComboBox interactivity is not
correct until something redraws the list, like scrolling.
I can make it work with an external button that calls invalidateList()
on the DataGrid, but I want to do that from within the renderer. I have
tried:
/** called from commitProperties */
private function setEnabled():void
{
this.enabled = !_oItem.disabledFlag;
DataGrid(_dgListData.owner).invalidateList();
}//setEnabled
But this does not seem to do anything.
Where, when and how should I make the invalidateList call from within my
renderer?
