C＃/ ASP.NET遍歷表

Question

我有一個由10行組成的表，每行包含3個字段（SKU，開始日期，結束日期）。我的目標是遍歷表格行並提取這些值。到目前爲止，我還沒有能夠提出一個可行的解決方案。下面是我到目前爲止有：

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// 
} 

代碼，表格佈局：

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

     <asp:TableHeaderRow id="Table1HeaderRow" 
      BackColor="GradientActiveCaption" 
      runat="server"> 
      <asp:TableHeaderCell 
       Scope="Column" 
       Text="Product SKU" /> 
      <asp:TableHeaderCell

       Text="Start Day/Time" /> 
      <asp:TableHeaderCell

Answer 1

做到這一點，而不是....

  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); 

         } 
        } 
       } 
      } 

你應該找到行內的控制'cells'control collection instead of the rows'control collection
