Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The client area starts at the (0, 0) location and extends to the (x, y) location.
Typically, you should not set the ClientSize of the control.Notes to Inheritors
When overriding in a derived class, be sure to call the base class's method so that the ClientSize property is adjusted.
For more information about drawing on controls, see Rendering a Windows Forms Control.
The following code example overrides the method to ensure that the control remains square. This example requires that you have a class that is either directly or indirectly derived from the Control class.
