設置下拉列表的值OnRowEditing

我在GridView中有一個下拉列表。我不希望DDL中的值在編輯模式下與視圖模式下相同，當gridview進入編輯模式時，DDL set的值爲第一個值爲默認值。設置下拉列表的值OnRowEditing

我試圖在填充和綁定GridView的編輯模式之前獲取值，但後來我得到空（nFolderId）。當我在綁定後嘗試nFolderId片段時，我得到默認值（意思是第一個值）。

那麼我怎樣才能讓DDL值從視圖模式進入編輯模式呢？

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) 
{ 
    GridView1.EditIndex = e.NewEditIndex; 
    GridViewRow row = GridView1.Rows[e.NewEditIndex]; 
    var nFolderId = Convert.ToInt32(((DropDownList)row.FindControl("DropDownListFolders1")).SelectedValue); 
    FillGridView(); 
    GridView1.DataBind(); 
}

我的aspx：

<asp:GridView ID="GridView1" runat="server" OnRowEditing="GridView1_RowEditing" DataKeyNames="strPositionId,tmVaRPosition,nFoldersId" 
      AllowSorting="True" AutoGenerateColumns="False" SkinID="gridviewGridlinesSkin" OnRowCancelingEdit="GridView1_CancelingEdit" 
      OnRowUpdated="GridView1_RowUpdated" OnRowUpdating="GridView1_RowUpdating" OnRowDeleted="GridView1_RowDeleted" OnRowDeleting="GridView1_RowDeleting" 
      EmptyDataText="No positions found" OnRowDataBound="GridView1_RowDatabound"> 
      <Columns> 
       <asp:TemplateField> 
        <ItemTemplate>

     </asp:GridView>

問：那麼，在下拉菜單的外觀和在這兩種模式下同樣的經歷 - 視圖模式和編輯模式？ – deostroll

@deostroll在視圖模式下，它只是一個標籤*，顯示值 – MrProgram

設置了selectedValue的價值

<div> 
     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"  DataSourceID="SqlDataSource1" 
    onrowdeleting="GridView1_RowDeleting">

     <asp:BoundField DataField="dd" HeaderText="dd" SortExpression="dd" /> 
     <asp:TemplateField HeaderText="ddd" SortExpression="ddd">
