列名称无效

Question

无法让我的代码工作。我有所有相同的名字，我仍然得到相同的错误告诉我“AwardName”无效。我列出下面的代码和堆栈跟踪。任何有关此问题的帮助将不胜感激。

<asp:GridView ID="GridView1"
                runat="server"
                DataKeyNames="AwardName"

                GridLines="None"
                AllowPaging="true"
                ShowFooter="true">

            </asp:GridView>

sqldatasource代码：

SelectCommand="SELECT [AwardName],[Recepient] FROM [Awards]"
            InsertCommand="INSERT INTO [Awards] ([AwardName], [Recepient]) 
                                  VALUES (@AwardName, @Recepient)">
