DataBinding: 'System.Data.DataRowView' does not contain a property with the name

问题:

I am getting this weird error... the primary key in my database is 'DocumentID' so I know that is not the issue. I am trying to get the select,edit & delete gridview buttons to work but I need the datakeynames to be set correctly for them to be available to use. any ideas?

<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]" /> 

Here is the stack trace...

回答1:

Well, you haven't selected the documentid column and hence it's not present in either datatable or dataview which you are binding to grid OR referencing that column through datatable.

Change your query to

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

It seems that your sqldatasource does not return the DocumentId column.

Maybe you should change the datasource definition to this:

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