ASP.NET でこのエラーが発生しています。そして、それは進行中のようです。あることを修正すると、別のエラーが発生します。ここで尋ねたこの以前の問題がありました: Issue with inserts and updates。今一番の答えで、コードを修正するのに役立つ多くのことを言われました。ただし、「DataKeyNames="ID"」を挿入した後、このエラーが発生すると言われました...理由がわかりません
ここで、グリッドビューに注意してください。私は を持っています"DataKeyNames="ID"。これは次にリンクされ<asp:BoundField DataField="ID" Visible="false" />
ます。スタック トレースは次のとおりです。
