DataGridView.ColumnHeaderCellChanged Event


Occurs when the contents of a column header cell change.

 event System::Windows::Forms::DataGridViewColumnEventHandler ^ ColumnHeaderCellChanged;
public event System.Windows.Forms.DataGridViewColumnEventHandler ColumnHeaderCellChanged;
member this.ColumnHeaderCellChanged : System.Windows.Forms.DataGridViewColumnEventHandler 
Public Custom Event ColumnHeaderCellChanged As DataGridViewColumnEventHandler 

Event Type



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

private void DataGridView1_ColumnHeaderCellChanged(Object sender, DataGridViewColumnEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
MessageBox.Show(messageBoxCS.ToString(), "ColumnHeaderCellChanged Event" );
Private Sub DataGridView1_ColumnHeaderCellChanged(sender as Object, e as DataGridViewColumnEventArgs) _ 
     Handles DataGridView1.ColumnHeaderCellChanged

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

End Sub
