Downloading file problem with ajax

[Bharani Mani]

Hello,
          I have a ASP.NET AJAX tree control whose data need to be downloaded to a file from server. I have a splitter control which has the tree control and a button. OnClick of that button, I save the file to disk on the server and redirect to a different page and call Response.TransmitFile(name) to send the file to client;. It works fine on local server. But on remote server, IE security blocks the file from downloading. But I clicked on the information bar in IE and clicked Download File, the page is refreshed but the file is not downloaded. All data in tree control is lost.

Any suggestions or clues..

Thanks,
Bharani

I fixed the problem myself. I put that button's id in PostBackTrigger and the file is saved without any security warning.
