在Aspx页中的代码:
<
EditItemTemplate
>
< asp:DropDownList ID = " DropDownList1 " runat = " server " >
< asp:ListItem Value = " 男 " > 男 </ asp:ListItem >
< asp:ListItem Value = " 女 " > 女 </ asp:ListItem >
</ asp:DropDownList >
</ EditItemTemplate >
< asp:DropDownList ID = " DropDownList1 " runat = " server " >
< asp:ListItem Value = " 男 " > 男 </ asp:ListItem >
< asp:ListItem Value = " 女 " > 女 </ asp:ListItem >
</ asp:DropDownList >
</ EditItemTemplate >
