[flexcoders] Unable to set ItemRenderer's value back to DataGrid's dataProvider

[jmorpher03]

Hi,

I have a Custom ItemRenderer, which displays a TextInput or a Label
based on another column's value in the DataGrid.
Here's the sample for the ItemRenderer:

MyItemRenderer.mxml

<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> ">
<mx:Canvas id="myRendererCan"/>
<mx:Script>   <![CDATA[
public var textField;
private var myLabel:Label;
private var myTextInput:TextInput;
override public function set data(value:Object):void {
  myRendererCan.removeAllChildren();
  if(value != null && value.colA == "M") {
   myLabel = new Label;
   myLabel.text = value[textField];
   myRendererCan.addChild(myLabel);
  }
        else {
   myTextInput = new TextInput;
   myTextInput.setStyle("backgroundColor", 0xFFFF0F);
   myTextInput.text =  value[textField];
   myRendererCan.addChild(myTextInput);
        }

     }
  ]]>
</mx:Script>
</mx:HBox>


In my Main.mxml , the DataGrid is as follows :
<mx:DataGrid editable="true">
  <mx:columns>
  <mx:DataGridColumn headerText="ColA" dataField="ColA" width="40"
editable="false"/>
  <mx:DataGridColumn headerText="ColB" dataField="ColB" width="60"
  itemRenderer="MyItemRenderer"
  editable="true"
  rendererIsEditor="true" />
  </mx:columns>
</mx:DataGrid>

I want to set the value which user enters in the "myTextInput" , back to
the ColB of the dataProvider.
I have tried a lot of examples, but none seem to work. Can anyone help
me with this.
I tried even by directly declaring a TextInput , rather than dynamically
adding it,
even then it does not work.

Thanks in advance.

Regards,

Asgar.
