将下拉列表添加到edittemplate，如下所示

add drop down list to edittemplate as following

<asp:Gridview AutoGenerateColumns="false" ID="gv" OnRowEditing="Row_Edit" ...................>
<Columns>
 ------------------------
 ------------------------
 <asp:TemplateField>
  <ItemTemplate>
  // add label to show data
  </ItemTemplate>
  <EditTemplate>
    <asp:DropdownList ID="ddl" runat="server">
    <asp:ListItem Text="Select" Value="0" />
    </asp:DropdownList>
   </EditTemplate>
</asp:TemplateField>
</Columns>
</asp:Gridview>
