드롭 다운 목록의 값 설정 OnRowEditing

Question

gridview 내부에 드롭 다운 목록이 있습니다. DDL의 값을 편집 모드에서보기 모드와 동일하게하지 않을 것입니다. 그리드 뷰가 편집 모드가되면 DDL 세트의 값이 기본값이됩니다.

필자는 채우기 전에 gridview를 편집 모드로 바인딩하려고했지만 null (nFolderId)을 얻습니다. 바인딩 후 nFolderId 스니 j을 시도하면 기본값 (첫 x 째 값)을 얻게됩니다.

그렇다면보기 모드에서 편집 모드로 유지하기 위해 DDL 값을 얻으려면 어떻게해야합니까? 내 영문

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(); 
}
