The dropdown portion of combobox is overriding the textbox part in Visual Studio 2012, in browsers (tried IE and Chrome), while it is normal in Visual studio 2010
What settings need to be tweaked please
It seems like your OffsetY value has been changed. When this value is set to zero it should display the dropdown right below the box. To lower the dropdown, simply enter a positive number (try 10) and the dropdown should appear lower than before.
I have provided a demo that should help you understand the OffsetY component of the RadComboBox: OffsetY Demo
I checked all the comboboxes the offset Y value is 0 but making it 10 solves the problem - only that I will need to do this for all the comboboxes.
This doesn't happen if I use VS 2010
