народ, помогите!!!! Вобщем такая ситуация:
1) динмаческий создаю Gridview (их количество заранее не известно и может варироваться)
2) создаю столбцы и вбиваю их в грид
3) столбцы можно сортировать
4) грид нормально выводится на экран со всеми данными

У меня все и вся создается только динамически, из статического только PlaceHolder

проблема:
страничка обновляется, но строки не сортируются...  подскажите что и как? я сам пока новичок в этом деле..Плиииииз!!!
 
Вот код:

    protected void APRFAssessment_Sorting(object sender, GridViewSortEventArgs e)
    {
   
        e.SortDirection = SortDirection.Descending;
    
      }

       
    protected void Page_Load (object sender, EventArgs e)
    {
        
          //-setting connecton to
