DataGridView.ColumnNameChanged Event

Definition

Occurs when the value of the Name property for a column changes.

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

Event Type

Examples

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

private void DataGridView1_ColumnNameChanged(Object sender, DataGridViewColumnEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnNameChanged Event" );
}
Private Sub DataGridView1_ColumnNameChanged(sender as Object, e as DataGridViewColumnEventArgs) _ 
     Handles DataGridView1.ColumnNameChanged

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

End Sub
