推荐答案

您只需要使用选择进行查询。就是这样。



当用户选择下拉列表时，获取SelectedValue并从TextBox中获取Text。然后相应地形成您的查询并使用ADO.NET在数据库上执行。接下来获取结果数据集并绑定到GridView。

You just need to make the query with the selections. That's it.

When user selects the dropdownlist, get the SelectedValue and from TextBox get the Text. Then form your query accordingly and execute on database with ADO.NET. Next get the resultant dataset and bind to the GridView.
