The OnMouseEnter method sets the ButtonState to Pushed if the left mouse button is pressed when the pointer enters the cell and visual styles are enabled for headers. For more information about visual styles for headers, see the DataGridView.EnableHeadersVisualStyles property.
This method is similar to the DataGridView.OnCellMouseEnter method. It is called in the same circumstances in which a DataGridView.CellMouseEnter event is raised, but it does not actually raise the event.
When overriding OnMouseEnter(Int32) in a derived class, be sure to call the base class's OnMouseEnter(Int32) method.
