Hi All, I have a MVC application and I am using a rich text box control in a textarea control. I have bind the page with the Model and fetching the data from the class properties. here is the textarea control to use the Text Editor

<textarea class="rchTxtAr limit-max-char-500" name="txtAddArActResponsibilty" id="txtAddArActResponsibilty"
                    rows="10" cols="90"></textarea

I am serializing the form and then post the form to save the data

var data = $("#myform").serialize();

$jUnt.ajax({
           url: "/mycontroller/SaveData",
            method: 'post',
	    type: 'html',
            data:data,
	    success: function (data) {}
            });

A potentially dangerous Request.Form value was detected from the client in...

Hi
following code worked for me even without [ValidateInput(false)]

/*------------------------------View---------------------------------*/

XML

<script src="../../Scripts/jquery-1.4.4.js" type="text/javascript"></script>

    <script>

        function onSubmit() {

            debugger;

            var data = $("#myform").serialize();



            $.ajax({

                type: "POST",

                url: "http://localhost:49941/Home/SaveData",

                data: "data=" + data,

                success: function (msg) {

                    alert("Data Saved: " + msg);

                }

            });

        }

    </script>

    <form action="SaveData.aspx" method="get" id="myform" onsubmit="return false">

    <textarea name="txtAddArActResponsibilty" id="txtAddArActResponsibilty" rows="10">

        cols="90"&gt;</textarea>

    <button value="Submit Data" type="button" onclick="javascript:onSubmit()">

        Submit Data

    </button>

    </form>

/*------------------------------Controller--------------------------------*/
[AcceptVerbs(HttpVerbs.Get)]

        public ActionResult SaveData()

        {

            return View();

        }



        [AcceptVerbs(HttpVerbs.Post)]

        public ActionResult SaveData(string data)

        {

            return View();

        }

$("#myform").serialize(); code will encode all our data so no need to write [ValidateInput(false)]

please modify your code according to the above code
