Telerik RadComboBox expanded far apart from the control !! (GUI Issue)

We are using Telerik Dropdownllist in one of our Asp.Net application.

Issue is that when we click on the dropdownlist which is on the bottom of the page, the expanded 'tray' of that raddropdownlist seems to detached from the dropdownlist and appears to the top of the page. Dropdownlist and expanded tray are far apart.

Attached screenshots which will be more clear for you regarding the scenario.

Any idea, what's going wrong here ?

Visual Studio 2008 / .Net Framework 3.5

3) Some of the relevant portion of this ASPX Page. You can see the <telerik:RadComboBox ID="uxRadComboAgent2"  there

If you could help us, it will be great!

When I add these properties for telerik dropdownlist ( OffsetX="-2" OffsetY="-657"  )
seems to be fixed. But it is not a permanent solution. If we scroll, again will have the same issue. tray will detach from dropdownlist. But not far away as it was before.

Telerik version I am using is 2008.2.826.35

Any permanent solution ?

Have you tried setting the EnableScreenBoundaryDetection property to "false" and ExpandDirection property to “Down"?
Rajkumar GsSoftware EngineerAuthor Commented:
Thanks for your suggestion.

When I set EnableScreenBoundaryDetection="false" for that Telerik Dropdownlist, a difference is there!
The expanded tray appeared some more near to the dropdownlist! But even now it is 'far away'.

Property named 'ExpandDirection' is not found for Telerik Dropdownlist. So instead I tried
ExpandAnimation-Type="OutBack"  - no result

Can you tell me which property will do the down animation ?

The ExpandDirection property is available since 2010.2.713

You can try to upgrade, the new version is 2010.2.826 or try it first with a trial version:

Thanks vadimc.

But upgradation of Telerik is beyond me. It's my company or client purchased this tool.

When I created a new page with the same Telerik Dropdownlist control, it is working fine without showing this 'misbehaviour'.

So I think something else may be the cause of this issue.
