sliding panel bar not closing

[Paul]

I have a sliding panel bar setup on my pages. Every time I click on the button to open it, the panel bar slides open, but it throws this error, "Object doesn't support property or method 'stopTransition'", and I can not close the panel bar.  I thought may be I did something wrong so I created a page and copied the example here, http://demos.telerik.com/aspnet-ajax/panelbar/examples/applicationscenarios/slidingpanelbar/defaultvb.aspx . When I tried running that it also threw the error and behaved the same way.

The version I am using is the latest one : 2016.2.607.45 .

There is another project that I have that has the sliding panel bar and that is working. The only difference with that project is that its running 2014.2.724.45. So what is the issue?

I found out that it works if I add the rad skin manager. Why would I need to add that?

Hello Paul,

Thank you for the provided information. We logged this as a bug in the controls from Q3 2014 onward and will do our best to fix it as soon as possible.

The presence of the SkinManager's SkinChooser can be used as a temporary workaround, until an official fix is available. If you don't want it visible on you page you can hide it with the following CSS rule, but it must be enabled (ShowChooser="true"):

#SkinChooser {
    display: none;
}

You can track the bug's status on our Feedback Portal.

As a token of gratitude for reporting the issue and providing additional information that helped us isolate it I updated your Telerik points.
