Question

请看下面的图片，它显示了DataGridView的智能标记。

DataGridView Smart Tags http://img199.imageshack.us/img199/5871/post517531249536112.jpg

现在我正在创建一个新组件，我希望它支持在智能标记中显示一些属性。如何将属性添加到智能标记？

Answer 1

我使用http://msdn.microsoft.com/en-us/library/default.aspx?q=smart+tag+windows+forms+designer。

结果，我找到了Walkthrough: Adding Smart Tags to a Windows Forms Component。

进行相同搜索的任何人都会找到相同的文章。

更新：该链接不再有效。我刚尝试搜索"smart tag windows forms designer"，发现"Walkthrough: Adding Smart Tags to a Windows Forms Component"是第一次搜索。 Google中的相同搜索显示"How to: Attach Smart Tags to a Windows Forms Component"为第一次点击，但显示与第二次点击相同的漫游。

您可以使用以下代码在自定义控件中查看示例代码。
