[Solved] Command Items not Exporting

[GP]

I have a radgrid that gets populated on the server side after a user enters in some parameters, and clicks the search button.  I have a radajaxmanager that updates the radgrid when button 1 is pushed.  (See code below.)

I tried to copy from the export demo how to use the command item buttons to export the radgrid to pdf/word/excel etc.  However, it is not exporting.  I put a breakpoint on the function called "RadGrid1_ItemCommand".  This function DOES get called when I click on an export button, and the if e.command statement does go to the correct export option I want.  (Ex. ExportToExcel).  However, when the program gets to the line: RadGrid1.MasterTableView.ExportToExcel(), nothing happens.  Am I missing some code?

Here's what I have so far.

Never mind.  I figured out what I was doing wrong.  I had to add an ajax control for grid 1 to update control grid 1, then it worked.  see below code.  I hope this might help someone else.  It certainly stumped me.

<telerik:RadAjaxManager runat="server">
        <ClientEvents OnRequestStart="onRequestStart" />
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Button1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGrid1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

It works now, and it doesn't break the ajax for the button either.  Yay!

Thanks anyway.

Thanks GP it helped me. That's exactly what I had been missing too!
