Have the renderer dispatch a bubbling event on change of the checkbox.
In the handler, you can access the item, and get the item index and the
checked state.  Use that to set the selectedIndex on the DataGrid.

 

Of course the usual itemRenderer recycling caveats apply.

[flexcoders] CheckBox itemEditor in DataGrid behaves erratic

[iko_knyphausen]

This one is really odd...
I have a DataGrid, which has the selectedItem of another grid (parent-grid)as a dataProvider. The "child"-grid hasa checkbox control as renderer and editor.It does perform nicely in the sense that when I change the selection of the "parent"-grid,all sub-records with selected boxes (data is set to "true") appear as expected, i.e. checked. 
Now, when Icheck/uncheck items inthe child-list the data bound to the parent-grid seems to get "mixed up" (checked items of this and other child-records thereafterappear checked or uncheckedat random). The odd thing is, if I change the renderer to TextInput and edit the checkbox itemsas texts ("true" and "false"), everything is honkey-dory and remains that way.
Here the 2 variants of the grid column in question. First as TEXTINPUT which works fine...
mx:DataGridColumn editable="true" itemRenderer="mx.controls.TextInput" editorDataField="text" rendererIsEditor="true" width="65" headerText="Member" dataField="member" textAlign="center" /
And here with a checkbox control that creates the issue...
mx:DataGridColumn editable="true" itemRenderer="mx.controls.CheckBox" editorDataField="selected" rendererIsEditor="true" width="65" headerText="Member" dataField="member" textAlign="center" /
Any ideas... ?Likethe aliens in Toy Story "I will be eternally grateful" for your advise ;-)
Still having fun, though...
