Hello,
I have the following problem with RadComboBoxes and Internet Explorer 8:
On a form I have about 12 RadComboBoxes, Skin Windows7.
When I open this form, the form loads almost completely but the form remains in a unresponsive state. It is not possible to do anything on the form. The cursor shape shows as an hourglass. At the same time, the iexplorer process consumes near 100% processor time. IE8 Javascript profiler says that a script of an embedded Telerik JavaScript resource needs a lot of time.
After about 10s the form is usable and user can make input click on buttons, etc..
The problem remains even the combo boxes are not bound or filled with any items.
When I replace the RadComboBoxes with ASP:DropDownList controls the problem disappears.
We want to use the RadComboBoxes, because we need LoadOnDemand, AutoComplete and virtual scrolling.
With IE6, IE7 and Firefox 3.x, 4 there is no such problem at all.
The version of the Telerik.Web.UI dll is 2010.2.929.35.
Is this a known issue? Do we need a more current version of Telerik controls? Is there a workaround?
All hints and solutions are welcome.
Regards
Rolf Cerff

Hello Rolf Cerff,
I would suggest you to upgrade to the more recent version of the RadControls for ASP.NET AJAX.
Greetings,

Hello Helen,
we've installed the Q3 2010 version of RadControls for ASP.NET AJAX. The problem disappeared. What I found is: there is also an performance issue when loading my page with an open Internet Explorer Developer bar.
Thank you and regards
Rolf Cerff
