Question

我得到了这个代码生成的表（我知道它看起来很糟糕，但它只是作为测试）：

 protected void Gen_Load(object sender, EventArgs e)
        {
            List<string> ParamList = new List<string>();
            ParamList.Add("Perforation");
            ParamList.Add("Top of perforation");
            ParamList.Add("Bottom of perforation");
            ParamList.Add("Well radius");
            for (int i = 0; i < 4; i++)
            {
                TableRow row1=new TableRow();
                TableCell cell1=new TableCell();
                cell1.BorderColor=System.Drawing.Color.DarkGray;
                cell1.BorderWidth=2;
                cell1.Font.Size = 11;
                cell1.Text=ParamList.ElementAt(i);
                TableCell cell2 = new TableCell();
                cell2.BorderColor=System.Drawing.Color.DarkGray;
                cell2.BorderWidth=2;
                cell2.Width = 200;
                TextBox text1 = new TextBox();
                text1.ID = "txtb_1" + i;
                text1.Width = cell2.Width;
                text1.Height = cell2.Height;
                cell2.Controls.Add(text1);
                TableCell cell3 = new TableCell();
                cell3.BorderColor=System.Drawing.Color.DarkGray;
                cell3.BorderWidth=2;
                cell3.Width = 200;
                DropDownList dlist = new DropDownList();
                dlist.ID = "dlist_1" + i;
                ListItem li1 = new ListItem("m");
                ListItem li2 = new ListItem("ft");
              //  if (i != 0)
               // {
                    dlist.Items.Add(li1);
                    dlist.Items.Add(li2);
             //   }
                dlist.Width = cell3.Width;
                dlist.Height = cell3.Height;
                cell3.Controls.Add(dlist);
                row1.Cells.Add(cell1);
                row1.Cells.Add(cell2);
                row1.Cells.Add(cell3);
                row1.ID = "id" + i;
                ParamTable.Rows.Add(row1);
            }
        }

那么如何从dropdownlist和textbox元素中获取数据呢？我假设我可以以某种方式使用元素ID来调用它们，但我找不到任何示例。

UPD： aspx

          <asp:Table CssClass="span9"  style="margin-top:2px; margin-bottom:5px;"   ID="ParamTable" runat="server">
                   <asp:TableHeaderRow >
                                <asp:TableHeaderCell  Font-Size="Medium" BorderColor="DarkGray" BorderWidth="2px"  >Parameters</asp:TableHeaderCell>
                                <asp:TableHeaderCell  Font-Size="Medium" BorderColor="DarkGray" BorderWidth="2px" >Value</asp:TableHeaderCell>
                                <asp:TableHeaderCell  Font-Size="Medium" BorderColor="DarkGray" BorderWidth="2px" >Units</asp:TableHeaderCell>
                    </asp:TableHeaderRow>
                   <asp:TableRow >
              </asp:TableRow>
           </asp:Table>

请参阅以下代码以获取每行的值：

for (int i = 0; i < ParamTable.Rows.Count; i++)
{
    var textBoxValue = ((TextBox)ParamTable.Rows[i].Cells[1].FindControl("txtb_1" + i)).Text;
    var dropDownValue = ((DropDownList)ParamTable.Rows[i].Cells[2].FindControl("dlist_1" + i)).SelectedItem.Text;
}

注意：我不会在任何列表中存储值。您可以根据您的要求使用POCO / Property类。

<强>更新

从aspx中删除<asp:TableRow ></asp:TableRow>并更新forloop，如下所述：

for (int i = 0; i < ParamTable.Rows.Count - 1; i++)
{
    var textBoxValue = ((TextBox)ParamTable.Rows[i].Cells[1].FindControl("txtb_1" + i)).Text;
    var dropDownValue = ((DropDownList)ParamTable.Rows[i].Cells[2].FindControl("dlist_1" + i)).SelectedItem.Text;
}
