OnKeyDown Method

DataGridViewButtonCell.OnKeyDown Method

Called when a character key is pressed while the focus is on the cell.

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

protected override void OnKeyDown(
	KeyEventArgs e,
	int rowIndex
)

Parameters

e
Type: System.Windows.Forms.KeyEventArgs

A KeyEventArgs that contains the event data.

rowIndex
Type: System.Int32

The row index of the current cell, or -1 if the cell is not owned by a row.

When activated by the SPACE key, this method updates the cell's user interface (UI).

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

Notes to Inheritors

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