Telerik.Web.UI.RadToolTip.prototype undefined

[TD78]

Hello
I have a problem with RadToolTip position on Chrome. I found a solution:
Telerik.Web.UI.RadToolTip.prototype._getPosRelativeToMouse = function (targetBounds) {...}
but I get an error js: 'prototype is undefined'.
Why?
Thank you

Hi Donato,

Please, make sure that the given overwrite is placed inside the form tag, just before its closing:

    ...
    <form id="form1" runat="server">
        <script type="text/javascript">
            Telerik.Web.UI.RadToolTip.prototype._getPosRelativeToMouse = function (targetBounds) {...}
        </script>
    </form>
</body>
</html>

Hi Vessy
Now I receive this error: 'TypeError: Telerik.Web.UI.RadToolTip is undefined' :-(

Hi Donato,

Can you verify that there are Telerik controls added on the page and the Telerik.Web.UI.dll is referenced to the project? If so, please, share the exact setup you have so we can examine it further.

Looking forward your reply,

Hi Vessy
Thanks for your reply
Telerik.Web.UI is referenced in the project.
What information do you want to know? I haven't create the project and I don't know where find setup information
Thanks

Hi Donato,

The following article contains details information about all settings and references that have to be added to a project so you can use the Telerik controls. You can go through the steps from it comparing them with you actual setup in order to see if all requirements are met:
