Please take a look at the pic below, as you can see, I have resized my page to fit within the windows, however, the horizontal scroller (as I have marked red), still show up like that (looks like my page is so so horizontally large), it makes my Visual Studio become hang sometime, due to the fact the page is so "large". Please help me how to fix it.
* I noticed that it's happen whenever I drop in any RadComboBox in the page. (The problem is gone after I remove ALL the RadComboBox on the page). Is it a bug within RadComboBox
