DataGridView.OnMouseDown(MouseEventArgs) DataGridView.OnMouseDown(MouseEventArgs) DataGridView.OnMouseDown(MouseEventArgs) DataGridView.OnMouseDown(MouseEventArgs) Method

Definition

Raises the MouseDown event.

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

Parameters

Exceptions

The control is configured to enter edit mode when it receives focus, but initialization of the editing cell value failed and either there is no handler for the DataError event or the handler has set the ThrowException property to true. The exception object can typically be cast to type FormatException.

Remarks

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

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