Question

我有一个由10行组成的表，每行包含3个字段（SKU，开始日期，结束日期）。我的目标是遍历表行并提取这些值。到目前为止，我还没有找到一个有效的解决方案。以下是我到目前为止：

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//
}

表格布局代码：

<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  
                Scope="column" 
                Text="Start Day/Time" />
            <asp:TableHeaderCell 
                Scope="Column" 
                Text="End Day/Time" />

这样做......

           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);

                         }
                    }
                }
            }

您应该在行'单元'控件集合中找到您的控件，而不是行的控件集合
