CommandArgument DataBinding问题

Question

我有一个sql数据集网格视图表，它显示来自数据库的值。我试图将命令指向SQL中的compName变量(如下面的代码所示)，但我始终得到以下错误：

"DataBinding：'System.Data.DataRowView‘不包含名为’compName‘的属性。“

我的C#代码：

protected void searchTheDB()
{
    string s = "SELECT compName As 'Company/Organization Name', btcAddr As 'Bitcoin Address', Premium_User as 'Premium User'," + 
    "upvote as 'Upvotes',downvote As 'Downvotes' FROM clientDataTable WHERE compName LIKE '%" + searchBox.Text + "%'";

    try
    {
        SqlConnection forSearch = new SqlConnection(connectionString);
        SqlDataAdapter search = new SqlDataAdapter(s, forSearch);
        DataSet dB = new DataSet();
        search.Fill(dB);
        searchGridView.DataSource = dB;
        searchGridView.DataBind();
        searchBox.Text = String.Empty;
    }
    catch (SqlException exp)
    {
        throw new InvalidOperationException("Sorry, the website is experiencing difficulties, please try again, error: ", exp);
    }
}

asp.net代码：

<asp:GridView ID="searchGridView" runat="server" CellPadding="10" ForeColor="#333333" GridLines="None" Height="161px" Width="935px" CellSpacing="5" HorizontalAlign="Justify" BorderStyle="Solid" OnRowCommand="searchGridView_RowCommand">
                     <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
                     <Columns>
                         <asp:TemplateField>
                              <ItemTemplate>
                              <asp:Button ID="DownButton" runat="server" CommandName="Upvote" CommandArgument='<%#Eval("compName")%>' Text="Upvote"> </asp:Button>
                              <asp:Button ID="UpButton" runat="server" CommandName="Downvote" CommandArgument='<%#Eval("compName")%>' Text="Downvote"> </asp:Button>
                              </ItemTemplate>
                         </asp:TemplateField>
                     </Columns>

                     <EditRowStyle BackColor="#999999" />
                     <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
                     <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
                     <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
                     <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
                     <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
                     <SortedAscendingCellStyle BackColor="#E9E7E2" />
                     <SortedAscendingHeaderStyle BackColor="#506C8C" />
                     <SortedDescendingCellStyle BackColor="#FFFDF8" />
                     <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
                 </asp:GridView>

非常感谢你的帮助！

请注意查询的外观：

SELECT compName As 'Company/Organization Name'

结果集中没有名为compName的列，只有Company/Organization Name。因此，数据集对象对compName一无所知。因此，理论上您的数据绑定应该如下所示：

CommandArgument='<%#Eval("Company/Organization Name")%>'

然而，在实践中，我并不完全确定这样的列名是否能正常工作，因为空间(不那么关心)和正斜杠(更关心)。因此，我会考虑简化列别名，甚至完全删除它们--您将不会将它们用于数据绑定以外的其他任何事情，对吗？
