DataGridViewHeaderCell.OnMouseDown(DataGridViewCellMouseEventArgs) DataGridViewHeaderCell.OnMouseDown(DataGridViewCellMouseEventArgs) DataGridViewHeaderCell.OnMouseDown(DataGridViewCellMouseEventArgs) DataGridViewHeaderCell.OnMouseDown(DataGridViewCellMouseEventArgs) Method

Definition

Called when the mouse button is held down while the pointer is on a cell.

protected:
 override void OnMouseDown(System::Windows::Forms::DataGridViewCellMouseEventArgs ^ e);
protected override void OnMouseDown (System.Windows.Forms.DataGridViewCellMouseEventArgs e);
override this.OnMouseDown : System.Windows.Forms.DataGridViewCellMouseEventArgs -> unit
Protected Overrides Sub OnMouseDown (e As DataGridViewCellMouseEventArgs)

Parameters

Remarks

The OnMouseDown method sets the ButtonState to Pushed if the cell is clicked with the left mouse button 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.OnCellMouseDown method. It is called in the same circumstances in which a DataGridView.CellMouseDown event is raised, but it does not actually raise the event.

Notes to Inheritors

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