DataGridViewHeaderCell.OnMouseEnter(Int32) Method


Called when the mouse pointer enters the cell.

 override void OnMouseEnter(int rowIndex);
protected override void OnMouseEnter (int rowIndex);
override this.OnMouseEnter : int -> unit
Protected Overrides Sub OnMouseEnter (rowIndex As Integer)



The index of the row containing the cell.


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.

Notes to Inheritors

When overriding OnMouseEnter(Int32) in a derived class, be sure to call the base class's OnMouseEnter(Int32) method.
