Javascript error on Mouseover a disabled radcombobox in a usercontrol, which act as an edit template of radgrid

[ankool]

Hi,

I am getting javacript errors while hovering over disabled radcomboboxes in a user control. I am using this usercontrol to display when I load radgrid edit template.
I am enabling and disabling combos based on values in edited row in pageload of usercontrol.ascx.cs and on moving the mouse over the disabled combos, I get error "Value must be a DOM element"

I did searched in telerik forums and located a post discussing similar issue and following solution was suggested there,

<script type="text/javascript" language="Javascript">
        var oldDomEvent = Sys.UI.DomEvent;
        Sys.UI.DomEvent = function(rawEvent) {
            if (rawEvent.srcElement && typeof (rawEvent.srcElement.getClientRects) == "undefined") return;
            var evt = new oldDomEvent(rawEvent); for (var o in evt) this[o] = evt[o];
        }
        for (var o in oldDomEvent) Sys.UI.DomEvent[o] = oldDomEvent[o];
    </script>

 This solution do prevent error on mouse hover but throws other javascript errors ( error with browser event handlers or similar) when I perform update or close usercontrol or click on edit command of another row.
Therefore , I need a better and stable solution than the script above to fix my error when I hover over disabled radcomboboxes.

Thanks

Hello ankool,

Indeed using the patch in this complex case is the way to work around the bug (which is essentially a browser bug).

I will try finding the cause of the new errors you are describing so that we fix them as well. Can you please provide me with the code of a page using the patch and showing the errors?

Kind regards,
Simon
