Updatepanel onupdating event

NET AJAX framework will intercept the postback and fire a partial postback instead.For purposes of demonstration, I’m going to add that to the On Click event of the container div: Now, clicking anywhere in the Update Panel will trigger a partial postback, targeting the Update Panel.

While it works much like __do Post Back, as long as the ASP.NET AJAX client framework is present, you should not call it directly. A blog isn't a blog without comments, but do try to stay on topic.The original __do Post Back method performs identically, but is more robust since it gracefully degrades to full postbacks when the ASP.

My IDs were mismatched from trying to shorten parts of the code for better display here.I’ve noticed a lot of discussion lately regarding methods to refresh an Update Panel via client script. While it does work, I never have been able to get past the kludgey nature of that solution. Many will advise you to use a hidden button control inside the Update Panel, manipulated via button.click(), to trigger a partial postback of the Update Panel.

However, on the client side, the most common solutions I’ve been seeing just don’t feel right.That’s a slightly modified version of the standard Update Panel Date Time example.Instead of the more commonly used Button_Click trigger, notice that the Update Panel’s On Load event is handled in code-behind.Anytime Update Panel1 is loaded or reloaded in a postback, Label1 will be updated to reflect the current date and time.Luckily, there’s an easy method for triggering a postback targeted at the Update Panel: __do Post Back().As long as the event target of a __do Post Back() call is an async trigger of an Update Panel, the ASP.
