Manager/Panel file download

[Reuven]

Am pulling my hair out on this...

By scenario is kind of complex, but I have a masterpage with a radajaxmanager, then a page with multiple use controls. In one of the controls, I have a button within a radgrid that I want to generate a download request:

Response.Clear()
Response.ContentType = "Application/msword"
Response.AddHeader("content-disposition", "attachment;filename=test.xml")
Response.Write(teststring)
Response.End()

Obviously, I need to disable AJAX for this postback...
In my grid, I have a GridTemplateColumm that has a btnGenerate
On the grid's ItemDataBound:
Dim sm As ScriptManager = ScriptManager.GetCurrent(Page)
sm.RegisterPostBackControl(CType(e.Item.FindControl("btnGenerate"), LinkButton))

But no matter what I try, when the Grid's ItemCommand is raised by the button, it remains an AJAX request.

Thanks,
Reuven
(I don't want to save the generated file nor run it through a handler to generate since it contains confidential data)

Hello Reuven,

You can cancel the AJAX request in the OnRequestStart client-side event. Here is how:

1. Attach the handler to RadAjaxManager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <ClientEvents OnRequestStart="requestStart" />

2. Put the JS code in the MasterPage

...
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<script type="text/javascript">
    function requestStart(sender, args)
    {
        if (args.get_eventTarget().indexOf("MY_BUTTON_ID") >= 0)
            args.set_enableAjax(false);
    }
</script>
...
