推荐答案

虽然您没有将其标记为ASP.NET，但基于问题内容，​​它看起来像是一个ASP.NET问题。



现在，你问的是Grid中的Cascading下拉列表。您需要具有Cascading Dropdown，然后根据下拉值对Grid数据进行过滤。以下将有所帮助：

在ASP.NET GridView中实现Cascading DropDownList [< a href =http://www.dotnetcurry.com/ShowArticle.aspx?ID=221target =_ blanktitle =New Window> ^ ]

使用GridView中的数据库示例的Ajax级联DropDownList [ ^ ]

Though you have not tagged it as ASP.NET, based on the question content it does look like an ASP.NET question.

Now, what you ask is a Cascading dropdown in Grid. You need to have Cascading Dropdown in place and then based on the dropdown values a filter on Grid data. Following will help:
