请问如何根据条件，动态的生成Datagrid中模板列的控件类型

[hyvgs]

怎么样才能根据页面信息，将模板列中的TEXTBOX换成DROPDOWNLIST
<asp:TemplateColumn> <ItemTemplate> <asp:TextBox id="txt_cj" Runat="server" text=''></asp:TextBox> </ItemTemplate>
</asp:TemplateColumn>

小弟是新手，请各位帮帮忙，急~~！谢谢

you have to do it in ItemDataBound event handler, but here is a simpler solution:

<asp:TemplateColumn>
<ItemTemplate> <asp:TextBox id="txt_cj" Runat="server" text='' Visible='<%# SomeCondition%>'></asp:TextBox>
<asp:DropDownList id="ddl" Runat="server" Visible='<%# !SomeCondition %>'></asp:DropDownList>
</ItemTemplate>
</asp:TemplateColumn>

replace "SomeCondition" with some expression which might be of the format of
(bool)DataBinder.Eval(Container.DataItem,"SomeColumn")

如何在ItemDataBound event handler里写代码，而且我需要的条件不在数据数据源中怎么办？
