Export RadGrid to pdf is blank

[Roukaya]

hello all ,
i try to export radgrid to pdf but it still blank,

this is my client side code :

         <telerik:RadGrid runat="server" ID="ReservationsGrid" MasterTableView-ShowHeadersWhenNoRecords="true" OnPdfExporting="ReservationsGrid_PdfExporting" OnNeedDataSource="ReservationsGrid_NeedDataSource" OnGridExporting="ReservationsGrid_GridExporting"
                    AutoGenerateColumns="false" AllowPaging="true" OnItemCommand="ReservationsGrid_ItemCommand" >
                    <PagerStyle PageSizes="10" />
                    <ExportSettings ExportOnlyData="true" Excel-Format="Html"></ExportSettings>
                    <MasterTableView CommandItemDisplay="Top" UseAllDataFields="true">
                        <CommandItemSettings ShowExportToPdfButton="true" ShowExportToExcelButton="true" ShowExportToCsvButton="true" ShowExportToWordButton="true" ></CommandItemSettings>
                        <Columns>
.........

and i've a radajaxmanager :

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <ClientEvents OnRequestStart="onRequestStart" />
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="ReservationsGrid">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="ReservationsGrid" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

with this script  function :

<script type="text/javascript">
    function onRequestStart(sender, args) {

        if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0 ||
                args.get_eventTarget().indexOf("ExportToPdfButton") >= 0 ||
            args.get_eventTarget().indexOf("ExportToWordButton") >= 0 ||
                args.get_eventTarget().indexOf("ExportToCsvButton") >= 0) {
            args.set_enableAjax(false);

        }
    }
</script>

my code behind is :

protected void ReservationsGrid_ItemCommand(object sender, GridCommandEventArgs e)
 {
     switch (e.CommandName)
     {
         case RadGrid.ExportToPdfCommandName:

             ConfigureExport();
             ReservationsGrid.MasterTableView.ExportToPdf();
             break;

         case RadGrid.ExportToExcelCommandName:
             ConfigureExport();
             ReservationsGrid.MasterTableView.ExportToExcel();
             break;

         case RadGrid.ExportToCsvCommandName:
             ConfigureExport();
             ReservationsGrid.MasterTableView.ExportToCSV();
             break;

         case RadGrid.ExportToWordCommandName:
             ConfigureExport();
             ReservationsGrid.MasterTableView.ExportToCSV();
             break;

         default:break;
     }

 }

 public void ConfigureExport()
 {
     ReservationsGrid.ExportSettings.ExportOnlyData = true;
     ReservationsGrid.ExportSettings.IgnorePaging = true;
     ReservationsGrid.ExportSettings.OpenInNewWindow = true;
 }

thanks in advance .

Hi,

Please make sure that the clientside event 'onRequestStart' is firing. You could receive a blank PDF file if the StaticHeaders/Scrolling are enabled.

Thanks,
Princy.

Hello Roukaya,

I was not able to reproduce the issue. Could you please provide your OnPdfExporting and OnGridExporting event contents? Additionally I prepared a small sample based on your code and attached it to this thread. Give it a try and let me know how it differs from your real setup.

Greetings,

Kostadin and Princy thank you ..

even telerik demo (Exporting grid to pdf) get blank file ..
