I have a gridview inside of an updatepanel and would like to allow the user to select a row which would generate a call to a class that outputs a stream back to the client. It looks like I can’t do this because the grid is inside of an update panel. Any ideas?

C#

    protected void gvResults_SelectedIndexChanged(object sender, EventArgs e)     {         RMATagsReport rpt = new RMATagsReport();         rpt.GenerateReport();     }

ASP.NET

<asp:UpdatePanel ID='upResults' runat='server' ChildrenAsTriggers='false' UpdateMode='Conditional'> <ContentTemplate>     <asp:GridView ID='gvResults' runat='server' AutoGenerateColumns='False' CellPadding='4'         ForeColor='#333333' OnSelectedIndexChanged='gvResults_SelectedIndexChanged' Width='100%'>         <RowStyle BackColor='#F7F6F3' ForeColor='#333333' />         <Columns>             <asp:BoundField DataField='CSTNO' HeaderText='DEALER' />             <asp:BoundField DataField='ORDNO' HeaderText='RMA NUMBER' />             <asp:BoundField DataField='CSTORD' HeaderText='DEALER PO NUMBER' />             <asp:BoundField DataField='ORDDTE' HeaderText='ORDER DATE' />             <asp:BoundField DataField='INVDTE' HeaderText='INVOICE DATE' HtmlEncode='false' />             <asp:CommandField SelectText='Print RMA' ShowSelectButton='True' />         </Columns>         <FooterStyle BackColor='#5D7B9D' Font-Bold='True' ForeColor='White' />         <PagerStyle BackColor='#284775' ForeColor='White' HorizontalAlign='Center' />         <SelectedRowStyle BackColor='#E2DED6' Font-Bold='True' ForeColor='#333333' />         <HeaderStyle BackColor='#3494CC' Font-Bold='True' ForeColor='White' HorizontalAlign='Left' />         <EditRowStyle BackColor='#999999' />         <AlternatingRowStyle BackColor='White' ForeColor='#284775' />         <EmptyDataTemplate>             <span style='color: Red;'>No RMA Tags Found With Specified Criteria. </span>         </EmptyDataTemplate>     </asp:GridView>     <div id='LoadingDiv' style='display: none; text-align: center;'>         <img src='Graphics/Icons/loading_lg.gif' />     </div>     <div id='ResultsDiv'>     </div> </ContentTemplate> <Triggers>     <asp:AsyncPostBackTrigger ControlID='btnSearch' EventName='Click' /> </Triggers>

  1. I’m doing a response.redirect on the index change now with the new page handling the report generation… This seems to work OK.

    EDIT
    While this seems to work, I am still open to other possibilities as I don’t want to have a page that’s only purpose is to output this document.
