不是呀，我说的是动态加入的验证控件不行，我要在代码页中加入asp.net中的验证控件，而且验证的控件也是在代码中动态生成的，我是这样加入的，可是不行，快救救我吧！！！！
//加入验证控件
       if (dt.Rows[i].ItemArray[cellCtr+11].ToString()=="int")
       {
         System.Web.UI.WebControls.RangeValidator rvValidate = new RangeValidator();
         rvValidate.ID="rv"+i+","+cellCtr;
         rvValidate.Type=ValidationDataType.Integer;
         rvValidate.ControlToValidate=textbox.ID;//指定需要验证的控件的ID。这个控件是在代码页中动态生成的。
         rvValidate.MaximumValue="10";
                              rvValidate.MinimumValue="1";
         rvValidate.ErrorMessage="aaaa";
         rvValidate.Display=ValidatorDisplay.Dynamic;
         tCell1.Controls.Add(rvValidate);
       }
TextBox tbAllocate = new TextBox();
tbAllocate.DataBinding += new EventHandler(this.BindDataAllocate);
tbAllocate.ID = strAllColumn;
tbAllocate.Width=70;
tbAllocate.BackColor=Color.LightGreen; Table Display=new Table();
//add a row
TableRow tr = new TableRow();
TableCell td = new TableCell();
td.Controls.Add(tbTarget);
tr.Controls.Add(td);
Display.Controls.Add(tr); container.Controls.Add(Display);
RangeValidator cvTarget=new RangeValidator();
cvTarget.Text="请输入数字(0-100000000)！";
cvTarget.Type=ValidationDataType.Integer;
cvTarget.MinimumValue="0";
cvTarget.MaximumValue ="100000000";
cvTarget.ControlToValidate=tbTarget.ID;
cvTarget.Display=ValidatorDisplay.None;
cvTarget.ErrorMessage="请输入数字(0-100000000)！";
container.Controls.Add(cvTarget);
自己看看，估计"tCell1.Controls.Add(rvValidate);"用得不对。
to worldtomev(烈火) ，  看不大懂，能否给予一定的解释。
1、生成一个需要验证的控件tbTarget。
TextBox tbTarget = new TextBox();
tbTarget.DataBinding += new EventHandler(this.BindDataTarget);
tbTarget.ID = strTargertColumn;
tbTarget.Width=70;
tbTarget.BackColor=Color.LightPink;
2、生成控件的容器Display并装入tbTarget。
Table Display=new Table();
//add a row
TableRow tr = new TableRow();
TableCell td = new TableCell();
td.Controls.Add(tbTarget);
tr.Controls.Add(td);
Display.Controls.Add(tr);
3、生成tbTarget的验证控件cvTarget并装入Display。（Control container）
container.Controls.Add(Display); //关键
RangeValidator cvTarget=new RangeValidator();
cvTarget.Text="请输入数字(0-100000000)！";
cvTarget.Type=ValidationDataType.Integer;
cvTarget.MinimumValue="0";
cvTarget.MaximumValue ="100000000";
cvTarget.ControlToValidate=tbTarget.ID;
cvTarget.Display=ValidatorDisplay.None;
cvTarget.ErrorMessage="请输入数字(0-100000000)！";
container.Controls.Add(cvTarget);

哎，还是不行，我把生成的需要验证的控件，和验证控件都放入了一个container中，但是需要验证的控件（一个textbox）竟然不显示了。代码如下
System.Web.UI.WebControls.TextBox textbox = new TextBox();
textbox.ID=i+","+cellCtr;
textbox.Width=55;
tCell1.Controls.Add(textbox);
     //加入验证控件
if (dt.Rows[i].ItemArray[cellCtr+11].ToString()=="int")
{
  Control container=new Control();
  container.Controls.Add(textbox);
  System.Web.UI.WebControls.RangeValidator rvValidate = new RangeValidator();
  rvValidate.Type=ValidationDataType.Integer;
  rvValidate.ControlToValidate=textbox.ID;
  rvValidate.MaximumValue="100000000";
                              rvValidate.MinimumValue="0";
  rvValidate.Display=ValidatorDisplay.Dynamic;
  rvValidate.ErrorMessage="请输入数字(0-100000000)！";
  container.Controls.Add(rvValidate);
}
