很急用，大家帮帮忙！！
 

解决方案 »

  1.   

    SqlDataSource1这个控件不存在。
      

  2.   

    那怎么办，添加SqlDataSource1也不行啊
      

  3.   


    类型的控件的 ID。未能找到 ID 为“SqlDataSource1”的控件。 你看你的代码页面没有SqlDataSource1这个没有就拖一个sqldatasource1进来 设置好sql语句即可。
      

  4.   

    实例
    <asp:SqlDataSource  ID="SqlDataSource1" Runat="server"
      SelectCommand="SELECT * FROM [Customers]"
      ConnectionString="<%$ ConnectionStrings:AppConnectionString1  %>">
     </asp:SqlDataSource>你看看后台代码给哪个控件设置了参数datasourceID="sqldatasource1"了。
