Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
For a horizontal Splitter control (a Splitter control docked to the top or bottom of a container), this value is the height of the resizable control. For a vertical Splitter control (a Splitter control docked to the left or right of a container), this value is the width of the resizable control. You can use the property in an event handler for the SplitterMoved or SplitterMoving events to determine the size of the control that the Splitter control is docked to and limit its width to a specified maximum width (or height if a horizontally docked Splitter control).
