DataGridView.RowHeaderCellChanged 事件

定义

用户更改行标题单元格的内容时发生。

public:
 event System::Windows::Forms::DataGridViewRowEventHandler ^ RowHeaderCellChanged;
public event System.Windows.Forms.DataGridViewRowEventHandler RowHeaderCellChanged;
public event System.Windows.Forms.DataGridViewRowEventHandler? RowHeaderCellChanged;
member this.RowHeaderCellChanged : System.Windows.Forms.DataGridViewRowEventHandler 
Public Custom Event RowHeaderCellChanged 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 RowHeaderCellChanged 。 此报告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.ShowConsole.WriteLine 消息替换为 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 RowHeaderCellChanged 事件相关联。

private void DataGridView1_RowHeaderCellChanged(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(), "RowHeaderCellChanged Event" );
}
Private Sub DataGridView1_RowHeaderCellChanged(sender as Object, e as DataGridViewRowEventArgs) _ 
     Handles DataGridView1.RowHeaderCellChanged

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

End Sub
