Help with AJAX updatepanel?

brett

I have an AJAX updatepanel in an aspx page. Inside the updatepanel is
a placeholder control, which loads various ascx files. This all works
fine. One of the ascx files also has an updatepanel in it. In the
updatepanel is an ASP.NET image button that does a postback. So, it
looks like this:

aspx.updatepane l.Add(LoadContr ol(ascx control))
--ascx.updatepane l
--imagebutton

After this ascx control loads, I click the image button and nothing
happens. However, from the 2nd click on, it works fine. Another ascx
controls loads and then the one in question loads again. The same
behavior occurs. The first click doesn't work but all after it does.
I also put a breakpoint in the image button click method. It only
hits on the 2nd click and after.

Any ideas why this happens?

Thanks,
Brett

I am having exactly the same AJAX problem. I have a few textboxes and
dropdownlists that are bound to the database.
After the user enters a customer ID and hit the [Retrieve Customer
Info] button, the application retrieves customer info and populates
these said controls.

But, the very first time the user enters the customer ID and clicks
the retrieve button, the controls don't get populated, they get
populated from the 2nd click on.

What's the problem? AJAX bug? I am using the beta version of AJAX.

AJAX using UpdatePanel and without it in the same code

by: =?Utf-8?B?T2xlZw==?= | last post by:

Hi, I'm wondering if anybody using ajax extensions where UpdatePanel tag is used in addition to existing ajax implementation where UpdatePanel wasn't used yet. So, there is already a web project where ajax is used, but not with UpdatePanel. (without extensions) Would I be able to use UpdatePanel tag along with the current implementation? Or there is a contradiction in older and newer ajax styles? It's all .NET 2.0 environment. Thanks,

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
