I'm using version 2010.1.309.35 of the RadControls.
Using reflector in the method RenderTable of RadComboBox I can see:
the str is afterwards assigned to the style of the table.
The problem is that in neither line that sets the width there is no ; at the end of the width. After "display:none" is also added and I would get something like width:60pxdisplay:none. (And I dont know why the display:none)
Anyway my problem is that in the browser the width is something like 177px and I don't know where that comes from.
