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 SelectedGridItemChanged 。 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 PropertyGrid1的 类型的PropertyGrid实例的项目中。 然后,确保事件处理程序与 SelectedGridItemChanged 事件相关联。

private void PropertyGrid1_SelectedGridItemChanged(Object sender, SelectedGridItemChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "NewSelection", e.NewSelection );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OldSelection", e.OldSelection );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SelectedGridItemChanged Event" );
}
Private Sub PropertyGrid1_SelectedGridItemChanged(sender as Object, e as SelectedGridItemChangedEventArgs) _ 
     Handles PropertyGrid1.SelectedGridItemChanged

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

End Sub
