DataBinding：'System.Data.DataRowView'不包含名稱爲

的屬性我得到這個奇怪的錯誤...我的數據庫中的主鍵是'DocumentID'，所以我知道這不是問題。我試圖獲得選擇，編輯&刪除gridview按鈕的工作，但我需要datakeynames設置正確，他們可供使用。有任何想法嗎？DataBinding：'System.Data.DataRowView'不包含名稱爲

<asp:GridView ID="GridView1" runat="server" DataSourceID="sdsDocuments" EnableModelValidation="True" 
     SelectedIndex="0" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" DataKeyNames="DocumentID, DocumentTitle, DocumentBody"> 
     <Columns> 
      <asp:BoundField DataField="DocumentID" HeaderText="DocumentID" ReadOnly="True" SortExpression="ID" /> 
      <asp:BoundField DataField="DocumentTitle" HeaderText="DocumentTitle" SortExpression="Title" /> 
      <asp:BoundField DataField="DocumentBody" HeaderText="DocumentBody" SortExpression="Body" /> 
      <asp:CommandField ShowSelectButton="True" ShowDeleteButton="True" /> 
     </Columns> 
    </asp:GridView> 
    <asp:SqlDataSource ID="sdsDocuments" runat="server" ConnectionString="<%$ ConnectionStrings:blcDocumentationConnectionString %>" 
     SelectCommand="SELECT [DocumentTitle], [DocumentBody] FROM [tblDocument]" />

這裏是堆棧跟蹤...

嗯，你沒有選擇的documentid列，因此它不存在於任何數據表或數據視圖，您綁定到網格或引用該列通過數據表。

查詢更改爲

SelectCommand="SELECT [DocumentID],[DocumentTitle], [DocumentBody] FROM [tblDocument]" />

看來你的SqlDataSource不返回DocumentId列。

也許你應該對數據源定義改成這樣：

<asp:SqlDataSource ID="sdsDocuments" runat="server" ConnectionString="<%$ ConnectionStrings:blcDocumentationConnectionString %>" 
    SelectCommand="SELECT [DocumentID], [DocumentTitle], [DocumentBody] FROM [tblDocument]" />
