DataGridView.ColumnHeadersBorderStyleChanged Event

public:
 event EventHandler ^ ColumnHeadersBorderStyleChanged;

public event EventHandler ColumnHeadersBorderStyleChanged;

public event EventHandler? ColumnHeadersBorderStyleChanged;

member this.ColumnHeadersBorderStyleChanged : EventHandler 

Public Custom Event ColumnHeadersBorderStyleChanged As EventHandler 

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ColumnHeadersBorderStyleChanged 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 ColumnHeadersBorderStyleChanged event.

private void DataGridView1_ColumnHeadersBorderStyleChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the DataGridView.ColumnHeadersBorderStyleChanged event.");
}

Private Sub DataGridView1_ColumnHeadersBorderStyleChanged(sender as Object, e as EventArgs) _ 
     Handles DataGridView1.ColumnHeadersBorderStyleChanged

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

End Sub
