Dynamic updatepanel not updating

control is a server control that helps you develop Web pages with complex client behavior that makes a Web page appear more interactive to the end user.

Writing code that coordinates between server and client to update only specified parts of a Web page usually requires in-depth knowledge of ECMAScript (Java Script).

In this post, I will show you how to load different user control in Update Panel from different menu item click.

I have found a lot of request in Ajax Forum and some of them are having misconception about this.

I am using a Modal Popup Extender with a Panel for udpating some values, and upon pressing the OK button on the popup, I need the Update Panel to update.

The Panel and the OK button control are in the Update Panel in the file, so as far as I know, it should cause an update. Instead, I have tried adding a hidden button, which lies as the first element in the Update Panel. Update(); **Old attempt of udpating** Button1_Click(date Modal OKButton, new Event Args()); Why does this not work?

Thanks, Atanu Children As Triggers has been true all along.

In this case you do load it before postback data are handled and user control comes loaded to Page_load event.If update a value with a popup, no change happens until the hidden button is pushed (this I have tried with the button visible). I have also tried adding the date Modal OKButton to the collection of triggers for the Update Panel - this does nothing as well. -Rasmus From the client-side click, you can refresh the Update Panel, see Also, see this post: this helps, -Damien I certainly agree with you that, when children makes a post back the update panel should update.

However, its server-side processing model has several drawbacks inherent in the technology, many of which can be addressed by the new features included in the Microsoft ASP. These extensions enable many new rich client features, including partial rendering of pages without requiring a full page refresh, the ability to access Web Services via client script (including the ASP. This whitepaper also assumes that you will be working with Visual Studio 2008, not Visual Web Developer Express, and will provide walkthroughs according to the user interface of Visual Studio (although code listings will be entirely compatible regardless of development environment).
