Error on opening appointment

[vasanthi r]

Hi,

We had installed Rad controls from the link (http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q1-2010-version-2010-1-309.aspx) and started working on the rad scheduler. Now we have upgraded it to the new version (http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q1-2010-sp2-version-2010-1-519.aspx).

When opening an appointment for the first time, we are getting  an alert message(attached with this thread). This happens only when opening the popup for the first time. Please help us resolve this issue.

Thanks,
Vasanthi

Hello Vasanthi,

The error seems to be caused by invalid markup on your page. You can verify this by disabling the RadAjaxManager or removing any UpdatePanels.

You can use the W3C Validator or this Firefox plug-in to check for invalid markup - unclosed tags and so on.

Kind regards,
