DataGridView.RowContextMenuStripChanged 事件

定义

ContextMenuStrip 属性更改时发生。

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

事件类型

示例

下面的代码示例演示了此成员的用法。 在此示例中,事件处理程序报告事件的发生情况 RowContextMenuStripChanged 。 此报表可帮助你了解事件发生的时间,并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件,请考虑将 MessageBox.Show 替换为 Console.WriteLine 或将消息追加到多行 TextBox

若要运行示例代码,请将其粘贴到包含名为 DataGridView1的 类型的DataGridView实例的项目中。 然后,确保事件处理程序与 RowContextMenuStripChanged 事件相关联。

private void DataGridView1_RowContextMenuStripChanged(Object sender, DataGridViewRowEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Row", e.Row );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowContextMenuStripChanged Event" );
}
Private Sub DataGridView1_RowContextMenuStripChanged(sender as Object, e as DataGridViewRowEventArgs) _ 
     Handles DataGridView1.RowContextMenuStripChanged

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

End Sub
