i dont know how to do this and getting depressed . please anyone help me ! :(

You don't need to change itemRenderer for that - just implement that code in your single item renderer. You can add listeners inside it and change the contents of the current cell.

I suggest when going into editable mode for your DataGrid: Also create an itemEditor for your Image column, make it an extended TextInput class. This extended TextInput class will change the data object's imageAddress/url when you are done editing ("itemEditEnd" event).

Let me know if this helps, thanks!
