Javascript Error after using Script Manager- : The message received from the server could not be parsed
<p>I am opening a ShowModalDialog on a button OnClientClick event and the javascript for it is:-</p>

<pre><code>&lt;script language="javascript" type="text/javascript"&gt;
        function openmodalWinLunch() {
            var variable1 = "Lunch";
            window.showModalDialog("ClockPopUP.aspx?code=" + variable1, "dialogWidth:290px;dialogHeight:270px,");
        }
</code></pre>

<p></p>

<p>On the Clock.aspx page i have a asp button on which i had written code :-</p>

<pre><code>protected void btnStop_Click(object sender, EventArgs e)
    {
        _nonProduction = new NonProduction();
        if (Session["LastNonProdTimeID"] == null)
        {
        }
        else
        {
            int NonProdTimeEntryID = Convert.ToInt32(Session["LastNonProdTimeID"]);
            //Updating the TimeSpent 
            isTimeSpentUpdated = _nonProduction.UpdateTimeSpentInDB(NonProdTimeEntryID);
            if (isTimeSpentUpdated == true)
            {

                string timespent = Convert.ToString(_nonProduction.GetTimeSpent(NonProdTimeEntryID));
                //string msg = "Total time consumed  in " +HiddenTaskname.Value.ToString()+": " + timespent.ToString() + " Minutes";
                Response.Write("&lt;script language='javascript'&gt;window.close();&lt;/script&gt;");
                Response.End();

            }
            else
            {
            }
        }



    }
</code></pre>

<p>Preveously every thing is working fine and this code is working as per my requirement. Just i had added Scriptmanager on the Clock.aspx as i m showing a clock which shows the elapsed time to the user. After that when i m clicking on the btn_Stop on CLock.aspx page i am getting this error message:-"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed."</p>

<p>Please guide me that how i solve this issue.</p>

<p>I found that what is the root cause of this error. It is happening because i m using Resonse.Write and other information is  <a href="http://weblogs.asp.net/leftslipper/archive/2007/02/26/sys-webforms-pagerequestmanagerparsererrorexception-what-it-is-and-how-to-avoid-it.aspx" rel="nofollow">Here</a></p>

<p>Guide me that how i fix this as i want to close the webpage after button click event.</p>
