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

'Declaration
Public Event RowHeadersWidthChanged As EventHandler

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RowHeadersWidthChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. Then ensure that the event handler is associated with the RowHeadersWidthChanged event.

Private Sub DataGridView1_RowHeadersWidthChanged(sender as Object, e as EventArgs) _ 
     Handles DataGridView1.RowHeadersWidthChanged

   MessageBox.Show("You are in the DataGridView.RowHeadersWidthChanged event.")

End Sub
