在用户控制页面的列表视图中访问动态创建的表的文本框

我正在使用asp.net和C#创建web模板。在我的用户控制页面中，我必须在列表视图中动态创建表。我只是从XML文件中读取数据，然后检索每个表的名称、列数和行数。在创建表格时，我会为每个单元格指定名称和id。在这个动态表中，一旦用户单击每行的编辑按钮，该行的所有单元格都将变为textbox。则用户可以改变该CCD_ 2的数据，但在我的更新功能中，我无法通过CCD_ 4访问这些CCD_。以下是我在ItemDataBound函数中创建的动态表代码：

System.Data.DataRowView rowView = e.Item.DataItem as System.Data.DataRowView;
TableRow tr_DataBound = new TableRow();
TableCell tc_DataBound = new TableCell();
for (int i = 1; i <= pkCounter + nonPkCounter; i++)
            {
                //tc_DataBound = new TableCell();
                tc_DataBound = new TableCell();
                TextBox tb = new TextBox();
                //(TextBox)e.Item.FindControl("td_EditTemp" + i);
                tb.Width = 110;
                tb.Text = rowView[i - 1].ToString();
                tb.ID = "td_EditTemp" + i;
                tc_DataBound.Controls.Add(tb);
                tc_DataBound.CssClass = "th_ItemTemplate";
                tr_DataBound.Cells.Add(tc_DataBound);
            }
        tr_DataBound.Cells.Add(tc_DataBound);
        Table table_Lv_ItemTemplate = (Table)e.Item.FindControl("Table_Lv_ItemTemplate");
        table_Lv_ItemTemplate.Rows.Add(tr_DataBound);

我的listview代码是：

<asp:ListView ID="lv_Uc_Module" runat="server"
                    onitemediting="lv_Uc_Module_ItemEditing" 
                    onitemcanceling="lv_Uc_Module_ItemCanceling"

                            </asp:TableRow>
                        </ItemTemplate>
                    </asp:ListView>

我在代码后面的更新函数中使用以下方法来访问textbox:上更改的数据

TextBox tb = (lv_Uc_Module.Items[e].FindControl("td_EditTemp" + i + "_" + e)) as TextBox;

你能指导我如何访问这些textboxes数据吗
感谢您的考虑。
