When using RadCombobBox in an update panel the RadCombobBox freezes and the others control won't make any partial post back.
This happens also with RadAjaxPanel and only in Visual Studio 2010 beta2.
When removing the RadComboBox everything works as expected.

In VS2008 works as expected.

Ex.

The error is simple to remake.
If you want i can send you the entire application.

By the way, i put in my webconfig file <pages clientIDMode= "AutoID"></pages> , without this the update panel won't work on content pages with or without RadComboBox.

But the error is the same without tthe clientIDMode set.

Thank you.

Hello alexandrupaul,

Could you use a debugger to see exactly where in the code the exception is thrown?

Kind regards,

i can't understand much of this :)
this is the function where it happens
_removeDropDown:function(){var c=this.get_dropDownElement().parentNode; 
c.parentNode.removeChild(c); 
if(this._disposeChildElements&&typeof(Sys.WebForms)!="undefined"){Sys.WebForms.PageRequestManager.getInstance()._destroyTree(c); 
}if(!$telerik.isSafari){c.outerHTML=null
}this._dropDownElement=null


if(this._disposeChildElements&&typeof(Sys.WebForms)!="undefined")
{
                Sys.WebForms.PageRequestManager.getInstance()._destroyTree(c);
}

i have added watch on c and Sys.WebForms.PageRequestManager.getInstance() and both are defined.

i think the _destroyTree function is not defined.

when i add a watch on the entire " Sys.WebForms.PageRequestManager.getInstance()._destroyTree(c); " throws Object doesn't support this property or method.

I tried applying the content of the Default.aspx file you so kindly provided in the zip file.  Unfortunately, after uncommenting the section and copying it to the page that experienced the problem, it had no effect.

 Would be too long to go into details, as I'm not even sure what's causing it yet...
Was mainly checking if this issue is somehow back...

The short version:
- a few controls in a panel (a radcombo among them).
- using javascript and appendChild to move the panel to a tablecell onclick.
- then moving the panel back out after a small async postback...

It used to work very well, did some upgrades, many changes, telerik updates included, and suddenly I realize (user report) that it's not working so well anymore... Not sure how to debug it. The javascript errors go from [above mentionned] to uncomprehensible errors in MS ajax code...

Hello Nicolaï,

As I understand - there have been a lot of changes in your project and that is why you face some difficulties researching the issue.
Let me suggest you create one simplified page with one RadComboBox on it and start adding your custom logic step by step.
After every step - please run the page and try to reproduce the issue.
Once you reproduce it - you will be able to detect what causes it.
