Questions tagged [updatepanel]

UpdatePanel is an ASP.NET AJAX control which allows page content to be updated asynchronously.

When adding an UpdatePanel control to your page, you can achieve a partial-page update of your page on a postback. Only the content in the UpdatePanel is refreshed, the other parts of the page remain unchanged. Use triggers for refreshing when it fires.
