Tooltip on radgrid row

[Luca]

I try to load a tooltip after click on a radgrid row, and the first time I click all works fine, but if I close the tooltip and click another row, I'm getting a javascript error

.cs code

        protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)
        {
            this.UpdateToolTip(args.Value, args.UpdatePanel);
        }

        private void UpdateToolTip(string elementID, UpdatePanel panel)
        {
            Control ctrl = Page.LoadControl("CustomerInfo.ascx");

            panel.ContentTemplateContainer.Controls.Add(ctrl);
            CustomerInfo details = (CustomerInfo)ctrl;
            details.ProductID = "test";
        }

no idea ?!

[Luca]

found the problem myself...

if the radgrid is within an <asp:UpdatePanel> instead a <telerik:RadAjaxPanel> the javascript raise the error posted.
