Question

我收到错误DataBinding：“'System.Data.DataRowView'在以下代码中的一个查询中不包含名为'p'的属性”。它在这一行显示错误：

  <asp:Label ID="lblPharmName" runat="server" Text='<%# String.Format("{0} {1}", Eval("p.Pharm_fname"), Eval("p.Pharm_lname")) %>'>
                </asp:Label>

以下是代码。但我怀疑使用的查询。任何建议将在查找导致错误返回的原因时受到赞赏。谢谢

Answer 1

这些

Eval("p.Pharm_fname"), Eval("p.Pharm_lname")

您的选择

中不存在

p.Pharm_fname + ' ' + p.Pharm_lname AS 'PharmName'

您需要更新您的Eval以评估PharmName或SQL以包含p.Pharm_fname和p.Pharm_lname并删除Eval中的别名引用。

DataBinding：'System.Data.DataRowView'不包含名为'p'的属性
