DataGridView.ColumnContextMenuStripChanged 事件

定义

在列的 ContextMenuStrip 属性更改时发生。Occurs when the ContextMenuStrip property of a column changes.

public:
 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 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中,事件处理程序报告 @no__t 的事件发生。In the example, an event handler reports on the occurrence of the ColumnContextMenuStripChanged event. 此报表可帮助你了解何时发生事件,并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件,请考虑将 @no__t 0 替换为 Console.WriteLine,或将消息附加到多行 TextBoxTo 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.

若要运行示例代码,请将其粘贴到包含名为 @no__t DataGridView 类型实例的项目中。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然后,确保事件处理程序与 @no__t 0 事件关联。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 );
messageBoxCS.AppendLine();
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)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ColumnContextMenuStripChanged Event")

End Sub
