关于Datagrid里的EditItemTemplate,该怎么处理

关于Datagrid里的EditItemTemplate
一个Datagrid

前台代码:

<Columns>
<asp:BoundColumn   DataField="Id">
</asp:BoundColumn>

<asp:TemplateColumn HeaderText="类型">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "TypeName").ToString()%>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList runat="server" ID="Dropdownlist2"   AutoPostBack="true"  OnSelectedIndexChanged="Dropdownlist2_SelectedIndexChanged" ></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateColumn>


<asp:BoundColumn DataField="ABC">
</asp:BoundColumn>

<asp:EditCommandColumn CancelText="取消" EditText="编辑" UpdateText="更新"></asp:EditCommandColumn>

</Columns>

后台代码:

protected void Dropdownlist2_SelectedIndexChanged(object sender, EventArgs e)
        {
            DropDownList ddl = (DropDownList)sender;
            TextBox strABC=????(我想找到DataField="ABC"这一列的TextBox)

        }

我想找到DataField="ABC"这一列的TextBox,请问这个问题应该如何解决?


[解决办法]
改为自定义模版。
