如何激活按钮上的SqlDataSource点击，我有两个sql数据源，2个文本框，两个按钮和一个网格视图
我想将1 sqldatasource绑定到一个按钮点击，另一个按钮绑定到另一个按钮，例如。
GridView2.DataSource =SqlDataSource2;
GridView2.DataBind();
除了它不起作用，它不会输出任何东西。当我测试查询它工作得很好

答案 0 :(得分：0)
那是因为您将AutoGenerateColumns设置为false并且您没有明确地绑定列，所以如果您想自动绑定它，请将其设置为true： -
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="True"
