radgrid inside radtreeview

[Swarup]

Hello,

I am looking for a sample code where in radtreeview, under each radtreenode there will be a radgrid depending on the grouping.
I created a radtreeview where I am adding the radtreenodes dynamically and then creating nodetemplate dynamically where I am creating a radgrid control. I have a editcommandcolumn as one of the column on the radgrid. The problem I am facing is binding the radgrid datasource in needdatasouce event. So if I have 3 nodes and under that 3 radgrids then needdatasource is firing 3 times attaching the last datasource results to all the 3 radgrids. Please provide me a sample code where needdatasource is handled for hierarchy of radgrids.

Thanks
