Recommended updatepanel usage in ASP.NET AJAX ?

1 New Member
In ASP.NET AJAX we can use the update panel control to update the partial page.
but if there are number of controls present on web form and many of them are dependent on another controls event i.e. the data is shown in them if certain event occurs of another control (e.g. cascading updates)

Then what should be the strategy of using updatepanel.
a)Can we use single update panel for all control ?specify reason?
b) For each control seperate updatepanel?spe cify reason?

Thanks.

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.updatepanel.Add(LoadControl(ascx control)) --ascx.updatepanel --imagebutton

Is anyone finding that cookies added to the Response.Cookies collection within pages which contain an UpdatePanel do not exist in the Request.Cookies collection when the page is posted back ? These should be complete page postbacks not partial postbacks, because the postback in question is not triggerred by a control inside the UpdatePanel (nor is it a trigger control for an UpdatePanel), but, not knowing all the details of how AJAX...

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,

Hello, On a webpage, create an UpdatePanel with two DropDownLists. Set AutoPostBack of DropDownList1 to true. In the SelectedIndexChanged method, refill DropDownList2 and set the focus to DropDownList1 using the ScriptManager SetFocus method. Use the Visual Studio debugger. Set a breakpoint on in the (!IsPostBack) part of the PageLoad method. Start the web application and continue after the breakpoint has been reached.

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,...
