[Ajay]

Hi,

I am using a RadGrid with grouping enabled. I am trying to export this grid data to a PDF but its not happening. On click of export button the grid does some processing but don't work at last.
Below is my code:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <script type="text/javascript" language="javascript">
        function requestStart(sender, args)
        {
            if (args.get_eventTarget().indexOf("DownloadPDF") > 0)
                args.set_enableAjax(false);
        }
    </script>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="CPH" runat="server">
<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

        <telerik:RadGrid ID="radGridShippedOrders" runat="server" GridLines="None" AllowPaging="True"
            PageSize="10" AllowSorting="True" AutoGenerateColumns="false" ShowStatusBar="true"
            HorizontalAlign="NotSet" AllowMultiRowEdit="false" OnNeedDataSource="radGridShippedOrders_NeedDataSource" 
            Width="100%" AllowMultiRowSelection="False" AllowFilteringByColumn="true" ShowGroupPanel="True">
            <PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="true"></PagerStyle>
            
            <ExportSettings ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true">
                 <Pdf PageTitle="SushiBar menu" />
            </ExportSettings>

            <MasterTableView GroupLoadMode="Client" CommandItemDisplay="Bottom">
                <CommandItemTemplate>
                    <asp:Button ID="DownloadPDF" runat="server" CommandName="ExportToPdf" Text="Export" />
                </CommandItemTemplate>
                <CommandItemSettings ShowExportToExcelButton="true" />
                <Columns>
                    <telerik:GridBoundColumn UniqueName="OACONO" HeaderText="OACONO" DataField="OACONO">
                    </telerik:GridBoundColumn>

                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
             <ClientSettings AllowGroupExpandCollapse="True" ReorderColumnsOnClient="True" AllowDragToGroup="True"
                AllowColumnsReorder="True">
            </ClientSettings>
             <GroupingSettings ShowUnGroupButton="true" />
        </telerik:RadGrid>
        
    </telerik:RadAjaxPanel>
</asp:Content>

protected void Page_Load(object sender, EventArgs e)
        {
            RadAjaxManager AjaxManager = new RadAjaxManager();
            AjaxManager = (RadAjaxManager)this.Master.FindControl("RadAjaxManagerMP");
            if (AjaxManager != null)
            {
                AjaxManager.ClientEvents.OnRequestStart = "requestStart";
            }
        }

Hello Ajay,

I don't recommend that you use RadAjaxPanel and RadAjaxManager side by side.
For basic scenarios I suggest you use RadAJaxPanel. On the other hand, if your scenario is a complex one, you may prefer to use RadAjaxManager given its flexibility.
Judging by your code, you have ajaxfied RadGrid two times hence the problem.
Ajaxifying controls wrapped in RadAjaxPanel and added to RadAjaxManager settings

Hi Daniel,

Thanks for the help, it worked.
However now I am facing another issue.

The parent RadGrid is having a child radGrid inside a NestedViewTemplate and this childRadGrid is having a export button.
I don't want a full page post back when someone clicks on the expand button, so I ajaxified the grid, but after doing this the export is not working.
So I added below line in page_load:
AjaxManager.AjaxSettings.AddAjaxSetting(radGridShippedOrders, radGridShippedOrders, null);

After the above line everything works fine (export and ajax loading) but the grid keeps displaying the loading icon in bottom left even after the request ends.

Thanks
Ajay
