RE: [flexcoders] drag&drop inside itemEditor in dataGrid...a tricky question

[Tracy Spratt]

For a renderer of that complexity, I would not use the DGs native editable
process, but would handle the dataProvider item updates within the renderer
itself.

Subject: [flexcoders] drag&drop inside itemEditor in dataGrid...a tricky
question

 

Hello all

I'd really appreciate your help on this.
I have a itemEditor in my datagrid (see attached code).. this is a drag&drop
text input... I drag words inside and it concatenates them to a comma
separated string...
I've embedded it in the grid like that:
<mx:DataGridColumn headerText="Prevent ctx" dataField="@prevent_ctxs"
rendererIsEditor="true" width="200"
itemRenderer="CtxTI" editable="true"/>

The problem is that the grid does not sense the itemBegin/itemEnd events
when I drag things inside..
and therefore does not activate the editor/automatically "pull" the data of
the itemEditor and puts it into the grid..

Can anyone figure a way to correct/around this?

Thanks in advance
