sql - 無効な列名の問題

Question

コードを動作させることができません。私はすべて同じ名前を持っていますが、「AwardName」が無効であるという同じエラーが表示されます。私のコードとスタックトレースを以下にリストします。この問題の助けをいただければ幸いです。

<asp:GridView ID="GridView1"
                runat="server"
                DataKeyNames="AwardName"
                DataSourceID="SqlDataSource1"
                Style="text-align: left"
                AutoGenerateColumns="false"
                GridLines="None"
                AllowPaging="true"
                ShowFooter="true">

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