Gets a value indicating whether the control has been disposed of.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When this property returns true, the control is disposed of and can no longer be referenced as a valid Windows control. Even though the instance of a control is disposed of, it is still maintained in memory until it is removed from memory through garbage collection. When a control is disposed, you cannot call its RecreateHandle method.
