DataGridViewButtonCell.OnMouseDown Method (DataGridViewCellMouseEventArgs)


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

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected override void OnMouseDown(
	DataGridViewCellMouseEventArgs e

If activated by depressing the left mouse button, this method updates the cell's user interface (UI).

This method is similar to the Control.OnMouseDown method. It is called in the same circumstances in which a Control.MouseDown event is raised, but it does not actually raise the event.

Notes to Inheritors:

When overriding OnMouseDown in a derived class, be sure to call the base class's OnMouseDown method so that registered delegates receive the event.
