Using SelectedIndexChanged to update second grid

[Joel]

I am working with the web mail demo and removing the LINQ references and trying to work within the confines of the code behind.

I have the treeview on the left updating the grid in the top right (radgrid1) properly.  When I click on a gridrow in the top right (radgrid1), I want to display detail text in the bottom right pane (radgrid2).  I don't care what control displays it, It will just be text.

I thought selectedindexchanged on radgrid1 would get me there but it appears to be a page lifecycle issue perhaps?  I have confirmed this event is firing.

    Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged
        RadGrid2.Rebind()
    End Sub

Any ideas?

Never mind, this is now resolved.
