<script type="text/javascript">
function AddData()
{
// code over here
}
</script>

<asp:ScriptManager ID="ScriptManager1" runat="server">
       </asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
         <asp:ImageButton ID="btnAdd" runat="server" ImageUrl="~/Images/Add.gif" OnClientClick="AddData(); return false;" />
         </ContentTemplate>
</asp:UpdatePanel>

The error is :

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

Hi Sagar,

This can be due to several issues. May be due to incorrect syntax, or undefined variables or unsupported mehods etc. Share your code inside the AddData() function.

Happy Coding
:)

try like this. It`s Working fine for me. Ithing In your logic you have errors

XML

<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown">
        </asp:scriptmanager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate >
    <asp:ImageButton ID="ImageButton1" runat="server" Height="50px" Width ="50px"  OnClientClick ="add(); return false;" ImageUrl ="~/images/images.jpeg"/>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>

    </asp:UpdatePanel>

Javascript:

C#

function add()
   {
   alert ('You Clicked image button');
   }
