这个跟页面一样啊:
<EditItemTemplate>
<asp:TextBox ID="txtBloodTypeName" runat="server" Text='<%# Eval("BloodTypeName") %>'
CssClass="textbox"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ControlToValidate="txtBloodTypeName"
Display="none" ErrorMessage="血型名称栏位,必须填写!" ValidationGroup="vg_Edit"></asp:RequiredFieldValidator>
</EditItemTemplate>
