Solved: 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

Attachments:-
1) & 2) screenshots (Click to view it in original size)
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!
