DataGridView.OnCellMouseDown Method (DataGridViewCellMouseEventArgs)


Raises the CellMouseDown event.

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

protected virtual void OnCellMouseDown(
	DataGridViewCellMouseEventArgs e

Exception Condition

The value of the ColumnIndex property of e is greater than the number of columns in the control minus one.


The value of the RowIndex property of e is greater than the number of rows in the control minus one.


This action would commit a cell value or enter edit mode, but an error in the data source prevents the action and either there is no handler for the DataError event or the handler has set the DataGridViewDataErrorEventArgs.ThrowException property to true.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnCellMouseDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

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