DataGridView.ColumnContextMenuStripChanged Event


Occurs when the ContextMenuStrip property of a column changes.

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


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

private void DataGridView1_ColumnContextMenuStripChanged(Object sender, DataGridViewColumnEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
MessageBox.Show(messageBoxCS.ToString(), "ColumnContextMenuStripChanged Event" );
Private Sub DataGridView1_ColumnContextMenuStripChanged(sender as Object, e as DataGridViewColumnEventArgs) _ 
     Handles DataGridView1.ColumnContextMenuStripChanged

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

End Sub
