若要运行示例代码, 请将其粘贴到包含名为PropertyGrid PropertyGrid1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type PropertyGrid named PropertyGrid1. 然后, 确保事件处理程序与SelectedGridItemChanged事件相关联。Then ensure that the event handler is associated with the SelectedGridItemChanged event.

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)
