Positioning problem in VIsta when Aero Theme is enabled
- by Adeel Rehman
Hi,
I have a Windows form which has tab pages. On a Tab Page, I have a Combo Box. When I click the combobox a drop down opens up just below the combo box to give the impression of a drop down. The drop down is a windows form and this is how I set its position
Popup.Location = control.PointToScreen(parentcontrol.PointToClient(new System.Drawing.Point(0, control.Height)));
Popup = drop down that opens below the combo box (Windows Form)
control = my combo box (Combo Box)
parentcontrol = the windows form on which the control is present (Parent Form)
Problem:- The X coordinate is not plotted correctly on the screen with Aero theme enabled. This works perfectly fine on XP (with some variance in y due to tablelayout panel i assume). But when i use the same code on Vista with Aero theme enabled the x-cordinate wanders away about 20-30 pixels. If I Turn Aero theme off on Vista, it works fine. I have found the X and Y coordiantes calculated in both cases are the same. But the way Vista draws these coordinates on the screen (when aero theme is enabled) is different.
Is there any solution to this problem?
Thanks,
Adeel Rehman.
