Video: Working with ASP.NET AJAX UpdatePanel Properties

This video tutorial demonstrates the affect the UpdatePanel's UpdateMode and ChildrenAsTriggers properties have on updating a panel's content.  The video starts out by discussing the UpdateMode property and shows why you may want to know about it when using multiple UpdatePanel controls on a single page.  It then discusses the ChildrenAsTriggers property and shows how you can prevent child controls from updating their parent UpdatePanel control.  Examples of nesting UpdatePanel controls to provide a master-details style view of data is also shown.

Thanks to Orcsweb for hosting my website (http://www.xmlforasp.net) and for giving me space to host videos!  If you're looking for a host I highly recommend them.  You won't find better service anywhere.

  • Hi,Dan Wahlin.
    I try to download the video for many times ,but it dosn't work.
    So, would you give me a new link for download it ?
    Thanks a lot.

  • Once you're on the page that hosts the video, right-click on the link under the video and select "Save Target As" in IE. FireFox will do the same thing but calls it "Save Link As".

  • Unless the network was temporarily down when you tried it, I'm not sure why you wouldn't be able to get to the page.  You might want to try it again because it's working OK and the page is accessible.  Here's the direct link to the page where the video is posted (same link as the one shown above):

  • I'm not sure unfortunately. Several thousand people have accessed it so I'm confident it's working properly, I'm just not sure why you wouldn't be able to get to it.
