I use updatepanel and updateprogress in my project. Whenever I add updatepanel to a page, then I should add updateprogress too.
Now I want to make a custom control that include both updatepanel and updateprogress.
If there are any controls like this, Can anyone give me its link. On other hands How to make a custom control likte that?
Raj Kaimal has a great example with downloadable source on his blog. I've used a variant of it for several projects and been very happy overall. It is a model update progress extender control.

I am aware that it is a well-known error. But the solutions available online are not working for me.
I have AJAX calendar extender inside an updatepanel.
When I do postback, it is trying to create the AJAX extendar controls twice, hence the problem.
Solutions available are saying to set debug=false, which makes the error disappear but duplicate controls are created on the page.
Each control is appearing twice.
What else I could try?
Thanks

Finally, I got it solved by moving controls into a separate update panel.
I had both GridView and Ajax extender controls in one update panel. The postback is happening when I clicked on gridview row.
Now I have GridView in one update panel and other controls in another update panel. That fixed it.
Hope it saves somebody's invaluable time
If you have this tag in your content or masterpage
<asp:ScriptManager ID="ScriptManager1" runat="server">
Add ScriptMode="Release" in the above tag.
We want to show Some fields of table in Detail view layout and want to update every fields individually. can we do this in asp.net
Use UpdatePanel and ScriptManager.
See here for details:Introduction to the UpdatePanel Control
Make use of AJAX that will do the task for you ...
You can make use of AJAX-Toolkit control UpdatePanel to do the partial update of your page. Also check : Implement ASP.NET AJAX with the UpdatePanel control
I have asp.net application and a TabContainer from AjaxControlToolkit on a form. There are 4 tabs, each containing UpdatePanel, hidden button and some custom .ascx (each with it's own javascript file). Buttons are triggers for panels to update the contents and they are triggered from the 'OnClientActiveTabChanged' event of the TabContainer.
This technique is described here and similiar here. It's pretty simple when looking at it.
The only problem I have is that the whole scenario works when used as a separate page but it doesn't seem to work when masterpage is around that page. Suddenly buttons act as full postback controls.
Do you have any idea what's the reason?
Assuming the buttons your referring to are on the master page, I think you'll want to register the master page buttons as update panel triggers.

I think that subject summs it pretty well...
I have created my custom validators that work great when I put them on page in design mode. However if I place them in a usercontrol, and then try to add this user control to the parent page via updatepanel, then my custom validators just won't trigger. They simply don't work.
Does anyone have any clue on what I have to do here?
.net 3.5
Custom validators trigger on postback.
My guess is that with the update panel, you're not posting back, hence the validator not firing.
I have a panel on an aspx page which contains an UpdatePanel.
This panel is wrapped with both a PopUpControl Extender as well as a DragPanel Extender.
Upon initial show everything works fine, the panel pops up and closes as expected and can be dragged around as well.
There is a linkbutton within the UpdatePanel which triggers a partial postback. I originally wanted to use an imagebutton but had a lot of trouble with that so ended up using the linkbutton which works.
Once the partial postback is complete I can no longer drag the panel around.
I would love to hear suggestions on how to fix this.
Has anyone else encountered this problem?
What did you do about it?
Do you know of any other way to accomplish this combination of features without employing other third party libraries?
Take a look at when the drag panel extender and popup control extender actually extend your panel.
Chances are those extenders work on an initialization event of the page. When the update panel fires and updates your page the original DOM element that was extended was replaced by the result of the update panel. Which means that you now have a control that is no longer extended.
I don't really know of an easy solution to this problem. What will probably work is if you can hook into an event after the update panel has updated the page and extend the panel again.
