A potentially dangerous Request.Form value was detected from the client (ctl00$cphMain$txCourseDescription="...ace="'MS Sans Serif&#...")

Question

My screen has a Telrik rad popup which populate on a button click(btnCourseDescription). I have taken a label to show html formated data and a textbox to work with code behind file. when I click on btnCourseDescription; Telrik's popup opens and and after submit it shows data on label and assign value to textbox using Javascript ... Here is my Javascript code...

<script type="text/javascript">
        function clientShow(sender, eventArgs)
        {
            //$find();
            var txtInput = document.getElementById("<%=lbCourseDescription.ClientID%>");
            sender.argument = txtInput.innerHTML;
        }

        function clientClose(sender, args)
        {
            if (args.get_argument() != null)
            {
                var lbInput = document.getElementById("<%=lbCourseDescription.ClientID%>");
                var txtInput = document.getElementById("<%=txCourseDescription.ClientID%>");
                lbInput.innerHTML = args.get_argument();
                txtInput.value = args.get_argument.htmlEncode();

            }
        }    
</script>

Now when I click on btnCourseDescription and and assign value using popup data submits successfully but when I want to update any other field means I am not updating HTML formatted data, HARDERROR occurs:

A potentially dangerous Request.Form value was detected from the client (ctl00$cphMain$txCourseDescription="...ace="'MS Sans Serif&#...").

Please suggest me what should I do?
