Asp.net使用数据绑定表达式与int

Question

我有一个名为Quotation的表，其中一列名为Gross_Total，类型为Int。当我使用Bind方法将它绑定到gridview colunm时，如下所示：

<asp:TemplateField HeaderText="Price">
    <ItemTemplate>
        <asp:Label ID="lblPrice" runat="server" Text='<%# Bind("Gross_Total") %>'></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

我得到一个很长的运行时错误：

  

DataBinding：'＆lt;＆gt; f__AnonymousType015 [[System.Int32，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.Int32，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，   版本= 4.0.0.0，文化=中立，   PublicKeyToken = b77a5c561934e089]，[System.String，mscorlib，   版本= 4.0.0.0，文化=中立，   公钥= b77a5c561934e089]，[System.Nullable1 [[System.Int32，   mscorlib，版本= 4.0.0.0，文化=中性，   PublicKeyToken = b77a5c561934e089]]，mscorlib，Version = 4.0.0.0，   文化=中性，   公钥= b77a5c561934e089]，[System.Nullable`1 [[System.Int32，   mscorlib，版本= 4.0.0.0，文化=中性，   PublicKeyToken = b77a5c561934e089]]，mscorlib，Version = 4.0.0.0，   Culture = neutral，Pu ...'不包含具有名称的属性   'Gross_Total'。

我的数据绑定方法：

 if (!IsPostBack)
    {
        MajesticEntities majesticentities = new MajesticEntities();
        var query = majesticentities.Quotations
                    .Select(quote => new
                    {
                        quote.Id,
                        quote.Bank,
                        quote.Customer.First_name,
                        quote.Customer.Surname,
                        quote.CPR,
                        quote.Car.Maker,
                        quote.Car.Type,
                        quote.Down_Payment,
                        quote.Gross_Total,
                        quote.Balance,
                        quote.Installments,
                        quote.Bank_Employee,
                        quote.Status_Bank,
                        quote.Notes_Bank,
                        quote.Status_Invoice,
                        quote.Notes_Invoice
                    });
        gridSample.DataSource = query.ToList();
        gridSample.DataBind();

        var query2 = from b in majesticentities.Banks
                     select b.Name;
        DropDownListBanks.DataSource = query2.ToList();
        DropDownListBanks.DataBind();
    }
