public virtual float ScaleHeight { get; set; }
A value representing the height.
Gets or sets the height of the client area of the control. If you assign a value to this property, the actual height of the control does not change, but the current height is expressed using the value that you provide. This lets you use a custom coordinate system. For example, you can set the ScaleWidth and ScaleHeight both to 100; then express all coordinates as percentage offsets.
