DataGridView.OnCellMouseDown(DataGridViewCellMouseEventArgs) DataGridView.OnCellMouseDown(DataGridViewCellMouseEventArgs) DataGridView.OnCellMouseDown(DataGridViewCellMouseEventArgs) DataGridView.OnCellMouseDown(DataGridViewCellMouseEventArgs) Method

Definition

Raises the CellMouseDown event.

protected:
 virtual void OnCellMouseDown(System::Windows::Forms::DataGridViewCellMouseEventArgs ^ e);
protected virtual void OnCellMouseDown (System.Windows.Forms.DataGridViewCellMouseEventArgs e);
abstract member OnCellMouseDown : System.Windows.Forms.DataGridViewCellMouseEventArgs -> unit
override this.OnCellMouseDown : System.Windows.Forms.DataGridViewCellMouseEventArgs -> unit
Protected Overridable Sub OnCellMouseDown (e As DataGridViewCellMouseEventArgs)

Parameters

Exceptions

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

-or-

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 ThrowException property to true.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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