hi. I have an issue that I can't seem to work around. I have a panelbar (pb1) on main.ascx. within pb1 i have two user controls each holding a radgrid ctlr1, and ctrl2 , respectively rg1 and rg2. I need a method to rebind rg1 and rg2 at the same time. For some reason I can't reference controls within the panelbar? What I was hoping to do was put a button on main.ascx, and using ajax manager control the two grids that way. This does work if I put a rg1.mastertableview.rebind() in the rg1_prerender event. the problem though is obvious that every time i call an action on the grid, it rebinds, so that mean I can't collapse any grouped items.
I'm pretty rookie at this type of thing so apologies if this should be very basic. my code is below for a basic setup
PS: I want to use a button to initiate the call as I am clicking it from a radwindow javascript.
note: sample is
main.ascx

    
                    <asp:Button ID="Button1" runat="server" Text="Button" /><br />
