如何为动态控件创建唯一的ID

Question

我一直在得到这个信息，并且没有任何帮助可以解决这个错误，我正在创建按钮的动态控件OnClick。但是收到此错误，发现多个具有相同ID的控件。 FindControl要求控件具有唯一的ID 。

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
        {
            string commandText = e.Argument.ToString().Trim();
            string[] splitdata = commandText.Split('&');
            commandText = splitdata[0];
            string controlName = splitdata[1];
            switch (controlName)
            {
                case "RadTextBox":
                    int cnt1 = FindOccurence("rtb") + 1;

                    TableCell txtlblRad = dCBL.GetWebUIControl("RadLabel", "", cnt1, cnt1, "Text Box:", "", 0,"");
                    TableCell txtRad = dCBL.GetWebUIControl("RadTextBox", "", cnt1, cnt1, "", "", 0,"");
                    TableRow txtRow = new TableRow();
                    txtRow.Cells.Add(txtlblRad);
                    txtRow.Cells.Add(txtRad);
                    Table1.Rows.Add(txtRow);
                    break;
