Assembly: System.Windows.Forms (in system.windows.forms.dll)
When possible, the dimensions of the control will be maintained. If this is not possible due to the screen layout, the control may be resized. To ensure that the control resizes neatly, you should implement docking and anchoring, and possibly any resize event-handler update code. If the user performs an action that causes the drop down to close, the control will be hidden and disposed by garbage collection if there is no other stored reference to the control.
