Как скрыть TextBox в GridView с TemplateField

Question

Вот мой Coding

Я хотел бы скрыть «txtQtyOrder10», если состояние после нажатия на кнопку поиска. когда я пытаюсь получить доступ из файла part.aspx.cs, появляется сообщение об ошибке msg.

У меня нет идеи, как получить доступ к текстовым полям для скрытия.

Вот некоторая кодировка для ссылки на то, что я пытаюсь сделать.

Любая помощь будет оценена.

Только вы можете скрыть или отобразить элементы управления внутри сетки В RowDataBound или любом случае сетки.

Попробуйте этот код ниже:

protected void gvOutput_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 

     try 
     { 

      if (e.Row.RowType == DataControlRowType.DataRow) 
      { 

      //get radio button value selected by user (default is all) 
      if (rdAll.Checked) 
       search.SearchType = rdAll.Value; 
      else if (rdBelowTrigger.Checked) 
       search.SearchType = rdBelowTrigger.Value; 
      else if (rdAboveTrigger.Checked) 
       search.SearchType = rdAboveTrigger.Value; 
      else if (rdBelowSafety.Checked) 
       search.SearchType = rdBelowSafety.Value; 
      else if (rdBelowXWeeksWPO.Checked) 
       search.SearchType = rdBelowXWeeksWPO.Value 

       //Hide the Textbox 
       TextBox txtQtyOrder10 = (TextBox)e.Row.FindControl("txtQtyOrder10"); 
       txtQtyOrder10.Visible = false; 

      } 
     } 
     catch (Exception ex) 
     { 
      LoggingComponent.Instance.LogMessage(bo.Enums.LoggingType.Error, DateTime.Now, ex.Message, bo.Enums.Module.Order, "gvProductsAdded_RowDataBound", bo.Enums.ApplicationLevel.FrontEnd, "Error en los Productos a Despachar"); 
      DisplayMessage(GetGlobalResourceObject("Messages", "UnknowError").ToString(), bo.Enums.MessageType.Error); 
     } 


    } 

Я надеюсь, что поможет вам.
