I am using RadGrid (5.0.1.0) control on a custom page in MOSS with a master page. When I tried to add ExportToExcel in button click event the event would fire on the first click but on subsequent clicks nothing would happen – all postbacks were suppressed. I tracked the problem to this line of code in the master page:
<form runat="server" onsubmit="return _spFormOnSubmitWrapper();">
_spBodyOnLoadWrapper() doesn’t seem to reset some internal variables in partial post backs.
When I remove the onsubmit event the page seems to works fine (<form runat="server">).
I don’t want to remove it since it’s a standard MOSS master page and it might break some other functionality.
Is there a workaround for this?
Are master pages supported by teleric controls in MOSS?
My custom and master pages live in:
\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS

I have been researching this and I don't have good news. I think we've hit an IE browser limitation here. SharePoint uses a window.onbeforeunload event handler in order to force users to save pages when they try to navigate away from them, and having that handler breaks all script execution after a postback (the grid export operation).
I think the only way to work around this is to use my colleague Vlad's hack, outlined in this forum thread and export your grid in a new browser window. Or maybe you can do a Response.Redirect in your button click event handler and export from another page.
I hope this information helps.
All the best,
