Response.BinaryWrite in RadAjaxPanel

[rmoynihan]

Hi,

I am creating a pdf programatically and then opening it in the browser.
I am doing this using

 response.BinaryWrite(pdfBytes);
 response.Flush();
 response.End();

It works fine when its not in a RadAjaxPanel but when it is inside the panel the document will not open.

Is there anyway to get it to work inside a RadAjaxPanel?

Thanks,

Ronan

Hello Ronan,

I recommend you either register your "export button" as a postback trigger or cancel AJAX on RequestStarted client-side event:
Exclude controls from ajaxifying
Export from ajaxified grid

I have the same problem with the Treeview, I am trying to let the end user to download a file through right click on Menu item, but the Browser didn't show the save dialog, here is the HTML CODE:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server"  Width="100%"
        LoadingPanelID="AjaxLoadingPanel2" OnRequestStart="onRequestStart">
  <telerik:RadSplitter ID="RadSplitter1" runat="server" ResizeMode="Proportional" OnClientLoad="resizeSplitter" OnRequestStart="onRequestStart" >
            <telerik:RadPane ID="RadPane1" runat="server" Width="20%" Scrolling="Y" OnRequestStart="onRequestStart">
                <table width="100%" cellpadding="0" cellspacing="0">
                    <tr>
                        <td>
                            <div style="height: 500px;">
                                <uctr:LSTreeView ID="uctrTreeView" runat="server" ParentPageName="translation"></uctr:LSTreeView>
                            </div>
                        </td>
                    </tr>
                </table>
            </telerik:RadPane>

Can you please Help, because i tried to disable Ajax on startRequest but this didn't work for me..

Hello Hanan,

Try the following:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function onRequestStart(sender, args)
        {
            if (args.get_eventTarget().indexOf("MyExportButton") >= 0)
                args.set_enableAjax(false);
        }
    </script>
</telerik:RadCodeBlock>
<hr />
<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" ClientEvents-OnRequestStart="onRequestStart">
    <telerik:RadTreeView ID="uctrTreeView" runat="server">
        <Nodes>
            <telerik:RadTreeNode>
                <NodeTemplate>
                    <asp:Button ID="MyExportButton" Text="Export" runat="server" />
                </NodeTemplate>
            </telerik:RadTreeNode>
        </Nodes>
    </telerik:RadTreeView>
</telerik:RadAjaxPanel>

I hope this helps.

I have a similar problem. I want Ajax Panel loading up while users are waiting to download the file. Is there a different workaround where ajax dont need to be disabled ?

Hello Apoorva,

Unfortunately it is not possible to export from radGrid without disabling the Ajax.
Instead of RadAjaxLoadingPanel I recommend you use RadProgressArea. For more information please examine the following links:
Using RadProgressArea
Custom Progress Monitoring

I hope this helps.
