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

'Declaration
Public Event RowDividerHeightChanged As DataGridViewRowEventHandler

The divider height is modified by setting the DividerHeight property.

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 RowDividerHeightChanged 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 RowDividerHeightChanged event.

Private Sub DataGridView1_RowDividerHeightChanged(sender as Object, e as DataGridViewRowEventArgs) _ 
     Handles DataGridView1.RowDividerHeightChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Row", e.Row)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowDividerHeightChanged Event")

End Sub
