IWindowsFormsEditorService.DropDownControl Method

Displays the specified control in a drop down area below a value field of the property grid that provides this service.

The drop down list Control to open.


The EditValue method of a UITypeEditor can call this method to display a specified control in a drop down area over the property grid hosting the editor which uses this service.

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 handling 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.
