前台
<asp:GridView ID="gvEventDispatcher" runat="server" DataKeyNames="EventCategoryID,DispatcherID"
AutoGenerateColumns="False" onprerender="gvEventDispatcher_PreRender"
onrowdatabound="gvEventDispatcher_RowDataBound"
onrowcancelingedit="gvEventDispatcher_RowCancelingEdit"
onrowediting="gvEventDispatcher_RowEditing"
onrowupdating="gvEventDispatcher_RowUpdating"
onrowcommand="gvEventDispatcher_RowCommand"
onrowdeleting="gvEventDispatcher_RowDeleting" >
<Columns>
<asp:TemplateField HeaderText="EventName">
<ItemTemplate>
<asp:Label ID="lblEvent" Text='<%# Eval("EventName") %>' runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlEvent" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="DispatcherName">
<ItemTemplate>
<asp:Label ID="lblDispatcher" Text='<%# Eval("DispatcherName") %>' runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlDispatcher" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="FormatterName">
<ItemTemplate>
<asp:Label ID="lblFormatter" Text='<%# Eval("FormatterName") %>' runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlFormatter" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="true" ShowDeleteButton="true" HeaderText="操作" EditText="修改" DeleteText="删除"
UpdateText="保存" CancelText="取消" ControlStyle-CssClass="LinkButton" />
<%--<asp:HyperLinkField Text="详细" DataNavigateUrlFields="ID" Target="_blank" DataNavigateUrlFormatString="RegionFormulaManage.aspx?ID={0}" />--%>
</Columns>
</asp:GridView>

<asp:LinkButton ID="lbtnAdd" CssClass="LinkBtn" runat="server"
onclick="lbtnAdd_Click">Create a EventDispatcher Domain</asp:LinkButton>

后台

if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))
{

DropDownList ddlFormatters = (DropDownList)e.Row.FindControl("ddlFormatter");
foreach (string formatterName in EventService.GetAllFormatterName())
ddlFormatters.Items.Add(new ListItem(formatterName));
DropDownList ddlEvents = (DropDownList)e.Row.FindControl("ddlEvent");
foreach (string eventName in EventService.GetAllEventCategoryName())
ddlEvents.Items.Add(new ListItem(eventName));
DropDownList ddlDispatchers = (DropDownList)e.Row.FindControl("ddlDispatcher");
foreach (string dispatcherName in EventService.GetAllDispatcherName())
ddlDispatchers.Items.Add(new ListItem(dispatcherName));
}

点击gridview编辑，前2个显示为label，第3个是dropdownlist
而点击外面linkbutton新增，3个都为dropdownlist

应该怎么改，现在编辑和新增都是dropdownlist
