[flexcoders] How to get selectedIndex from itemRenderer

[Howard Fore]

Hey,

I've got a DataGrid that's using an inline itemRenderer of a ComboBox for
one of the DataGridColumns. How can I get the selectedIndex of that
ComboBox? There's a default sort on the DataGrid and the DataGrid is
user-sortable as well, so the selectedIndex isn't going to mirror the index
of the selected row in the DataGrid. I need it to pass to a ComboBox in a
popup that will appear when the user double clicks it.

Are you looking for the index of the DataGrid dataProvider item?

 

If your dataProvider is a collection, you can use
Collection.getItemIndex(item).  If XML, you can use node.childIndex().
Of course both of those require that you have the needed references
available in your renderer.  ComboBox implements
IdropInListItemRenderer(something like that) so has access to listData,
thus the dataProvider.  Or I suppose you could use outerDocument to get
to the dataProvider.

You probably want to get the selectedItem and then look for it in your data 
provider using indexOf, getItemIndex,..
