Exception Details: System.Web.HttpException: Multiple controls with the same ID 'ctl00' were found. Trace requires that controls have unique IDs.

In .aspx file I am having one table 
  <asp:Table ID="mytable" runat="server" HorizontalAlign="Center" Width="100%" CellPadding="4"
                                        CellSpacing="0" BorderStyle="None">
                                    </asp:Table>

for the above table I am dynamically adding the RadGrid with properties in the class file.Refer the code below

 public class Home : MyHtmlControls
    {
     private RadGrid HVRGrid111 = new RadGrid();

private void GetClassicRadgrid(ref HtmlTableCell MyCell)
        {
        

            DataSet myobjdr = new DataSet();
            DataSet myds = new DataSet();
            string _DelviewUrl;
            string _EditUrl;
            string delJavaScriptStr;
            string _hprlnkUrl;


            GridBoundColumn mybound = new GridBoundColumn();
            GridTemplateColumn myTemplate;
            GridHyperLinkColumn myHyperLink = new GridHyperLinkColumn();

            try
            {
                delJavaScriptStr = "<script language=\"javascript\">\n";
                delJavaScriptStr += "<!--\n";
                delJavaScriptStr += "function Delete_" + _TableName + "(option,option1,option2,option3,option4,option5,option6,option7,option8)\n";
                delJavaScriptStr += "{\n";

                delJavaScriptStr += "var del = window.confirm('Are You Sure you want to delete ?');\n";
                delJavaScriptStr += "if (del)\n";
                delJavaScriptStr += "{\n";
                delJavaScriptStr += "openwin1('Delete.aspx?dbmode=del&tblid=' + option + '&Mode=' + option1 + '&UrlPath=' + option2 + '&uMode=' + option4 + '&uColid='+ option5 + '&uid='+ option6 + '&id=' + option3 + '&uTabid=' + option7+'&rMode='+option8,'400','200','no');\n";
                delJavaScriptStr += "}\n";

            {
                PutErrorPage(ref MyCell, "Error While Creating View !!!!<br>" + ex.ToString());

}
