C#/ASP.NET Iterate Through Table

Question

У меня есть таблица, состоящая из 10 строк, каждая строка содержит 3 поля (SKU, Дата начала, Дата окончания). Моя цель - перебирать строки таблицы и извлекать эти значения. До сих пор я не мог найти рабочего решения. Ниже то, что я до сих пор:

protected void btnVerify_Click(object sender, EventArgs e) 
{ 
    //START LOOP THROUGH TABLE ROWS// 
    foreach (TableRow row in Table1.Rows) 
    { 
    foreach (Control ctrl in row.Controls) 
    { 
     //CONTROL IS TEXBOXT: EXTRACT VALUES// 
     if (ctrl is TextBox) 
     { 
     TextBox txt = (TextBox)ctrl; 
     Label lbl = new Label(); 
     lbl.Text = txt.Text; 
     PlaceHolder1.Controls.Add(lbl);    
     }  
    }     
    } 
    //END LOOP THROUGH TABLE ROWS// 
} 

код для сервировки:

<asp:Table id="Table1" runat="server" 
     CellPadding="3" 
     CellSpacing="0" 
     GridLines="both" 
     Caption="Sample Table" Width="640px">

Сделайте это вместо того, чтобы ....

  foreach (TableRow row in tbl.Rows) 
      { 
       foreach (Table cell in row.Cells) 
       { 
        foreach (Control ctrl in cell.Controls) 
        { 
         //CONTROL IS TEXBOXT: EXTRACT VALUES// 
         if (ctrl is TextBox) 
         { 
          TextBox txt = (TextBox)ctrl; 
         Label lbl = new Label(); 
         lbl.Text = txt.Text; 
         PlaceHolder1.Controls.Add(lbl); 

         } 
        } 
       } 
      } 

Вы должны найти элементы управления внутри строк 'cell' вместо коллекции контрольных строк строк
