    </telerik:RadGrid>
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
</form>

RadGrid1 fires perfect, RadGrid2 fires perfect, and RadGrid3 loads but when editing the command never fires.  I set my break point and only hits when loads but not when hit the view / edit.  Thanks in advance.

Hi Jon,

From your code I see that your scenario is like the Update/Insert/Delete in Hierarchy demo so I recommend that you reorganize your data binding and use declarative relations as in the demo.
I also suggest that you see the Automatic operations in hierarchical grid with SqlDataSource control code library.

If your problems continue, I recommend that you open a formal support ticket and attach a sample working project replicating the issue.

Best wishes,
Mira
