为什么绑定的textbox控件不显示内容

Question

for (int i = 1; i <= 10; i++)
            {
                Ibasecn_System_Commission commission = Ibasecn_System_CommissionManager.GetCommissionByCommissionId(i);
                string txtbase = "txtBase" + Convert.ToString(i);
                string txttop = "txtTop" + Convert.ToString(i);
                string txtdeduct = "txtDeduct" + Convert.ToString(i);
                TextBox txtBase = new TextBox();
                TextBox txtTop = new TextBox();
                TextBox txtDeduct = new TextBox();
                txtBase.ID = txtbase;
                txtBase.Text = Convert.ToString(commission.Commission_Base);
                txtTop.ID = txttop;
                txtTop.Text = Convert.ToString(commission.Commission_Top);
                txtDeduct.ID = txtdeduct;
                txtDeduct.Text = Convert.ToString(commission.Commission_Deduct);
            }用断点运行过，有值，也分别对应上了，可就是浏览的时候，页面上的控件内容全是空的，这是为什么啊？

Answer 1

txtDeduct.ID = txtdeduct; 关闭这句看看有没有值
txtDeduct.Text = Convert.ToString(commission.Commission_Deduct);
