自定義控件與PropertyGrid不兼容

我有一個實現自定義ToolStripItem的類。在設計時嘗試將項目添加到ContextMenuStrip之前，似乎一切都很順利。如果我嘗試直接從ContextMenuStrip添加自定義控件，則PropertyGrid會凍結並且不會讓我修改Checked或Text屬性。但是如果我進入ContextMenuStrip PropertyGrid並通過Items(...)屬性添加我的自定義控件，我可以在該對話框中很好地修改自定義控件。我不確定如果我在某個地方遺漏了某個屬性，如果它存在底層代碼的問題。這裏是CustomToolStripItem類的一個副本。正如你所看到的，它是一個非常簡單的課程。自定義控件與PropertyGrid不兼容
