[Solved] With multiple grids on one aspx page, how to get second and third grids to update

[Shannon]

I have three grids on one aspx page.  The second and third grids are dependant upon the first grid (in that each time the selected row changes for the first grid, the second and third grids data changes).  The selected values are able to change correctly on all grids, however when trying to edit or insert an item into the second or third grid, the grids disappear and i can't get into any of the events to debug.  Here's the problematic aspx page:

 <h3>Media</h3>

    <asp:Label ID="lblErrorMessage" ForeColor="Red" runat="server" />

    <telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AllowPaging="True"

Hello Shannon,

Do you have a RadAjaxManager on your page?

If you have one, please try adding to its settings the settings required to perform edit/update/delete/insert operations in RadGrid using an external form as shown in the Editing with external form demo.

Hi Shannon,
Did you work out the issue?
I am having a very similar issue, but in IE only (firefox works great!).
