Raises the NewRowNeeded event.
protected:
virtual void OnNewRowNeeded(System::Windows::Forms::DataGridViewRowEventArgs ^ e);protected virtual void OnNewRowNeeded (System.Windows.Forms.DataGridViewRowEventArgs e);abstract member OnNewRowNeeded : System.Windows.Forms.DataGridViewRowEventArgs -> unit
override this.OnNewRowNeeded : System.Windows.Forms.DataGridViewRowEventArgs -> unitProtected Overridable Sub OnNewRowNeeded (e As DataGridViewRowEventArgs)Parameters
A DataGridViewRowEventArgs that contains the event data.
Exceptions
The row indicated by the Row property of e does not belong to this DataGridView control.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnNewRowNeeded 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 OnNewRowNeeded(DataGridViewRowEventArgs) in a derived class, be sure to call the base class's OnNewRowNeeded(DataGridViewRowEventArgs) method so that registered delegates receive the event.
