[Solved] Sys.WebForms.PageRequestManagerParserErrorException PostBack in RadAjaxManager

[William]

Goal is to have a form with RadAjaxManager, but with one Button
which posts back normally and writes out an Excel file via Response.Write(...)
So, RadAjaxManager just needs to let this button be implemented without any Ajaxification.

Already looked at
http://www.telerik.com/community/forums/thread/b311D-bddbka.aspx

What didn't work

• Added EnableEventValidation="false" to button
  <asp:Button ID="btnExportToExcel" runat="server" Text="Export to Excel" Width="96px" Enabled="False" EnableEventValidation="false" /></td>

• Added RadScriptManager1.RegisterPostBackControl(btnExportToExcel) to Page_Load
  
  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
         RadScriptManager1.RegisterPostBackControl(btnExportToExcel)
  End Sub

Using Telerik AJAX Manager v2008.1.515.20

All the Ajaxification works great.  If I set RadAjaxManager1.EnableAJAX = False, it also works fine.

Any suggestions to make this button fire without AJAX?

Hi William,

What are the AjaxSettings for the AjaxManager - does it ajaxify a container containing the button and thus prevents you from easily resolving this by simply not including the button in the AjaxSettings?
You can also disable ajax only for this specific button directly from the AjaxManager by hooking up to the client-side OnRequestStart event:

  <script type="text/javascript"> 
            function mngRequestStarted(ajaxManager, eventArgs) 
            { 
              if(eventArgs.EventTarget == "MyButton") 
              { 
                 eventArgs.set_enableAjax(false);
              } 
            } 
            </script>

Hope this helps.

Sincerely yours,
