Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The method forces a handle to be created for the control and its child controls. This method is used when you need a handle immediately for manipulation of the control or its children; simply calling a control's constructor does not create the Handle.
does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children.
