    I am recieving a flicker in firefox when i click to expand the parent item.  The sub menu items show for a split second at the bottom of the panel bar and then it expands.  Has anyone else ran into this.  I am populating the whole menu from code behind.  Also in safari, the text is not clickable, only the little white area in front of the text is clickable.  I appreciate all your help in advance.

    Hi Joshua,

    About the first problem - do you use the Default skin? If so, could you try it with another skin -for an example Outlook and tell us how it goes.

    About the second problem - we are not able to reproduce the problem in Safari at our side. Could you reproduce it with one of our examples? Also, could you tell us the version of the browser you use?

    Kind regards,

    Rosi,

    Joshua and I work together and have narrowed the issue down.  We tried a few different skins to see if that was part of the issue.  When we switched to the "Telerik" skin, it caused the flicker to go away in Firefox on Windows, but the issue still exists in Firefox on the Mac.  If we remove the expand navigation it seems to work fine, but when expand navigation is set to anything, it shows the flicker before it starts the animation.

    If you put an expand navigation type on your "http://www.telerik.com/DEMOS/ASPNET/Prometheus/Panelbar/Examples/Functionality/Hierarchical/DefaultCS.aspx" demo, you should see the issue in Firefox on the Mac.

    Max OX 10.3.9
    Firefox 2.0.0.14

    Thanks,
    John

    Rosi,

    Thanks for your last reply.  We opened a support ticket yesterday and tried the latest build and it still doesn't work.  Here is the URL to a development version of the current project we are working on where you can see the problem.

    http://kohls.beckerdesign.net/Content.aspx

    If you view it on Mac OS 10.3 or higher using Firefox 2.0 or higher, you will see the PanelBar flicker before it starts the animation.

    I have built our project against the source code and have narrowed the problem down a little, but haven't been able to fix it.

    In RadPanelItem.js in the "_displayChildren" function, when the following line is set and the object is set to visible, it forces the panel bar to open briefly before it start the animation.  This causes it to flicker in Firefox.

    aniamtionContainer.style.height = "auto";

    If the height is not set to "auto" the PanelBar doesn't animate smoothly, but it doesn't have the flicker problem.

    Hi John,

    We have tried to reproduce the problem, but it seemed that it worked as expected at our side. Please see the attached movie. Could you please provide us with steps to reproduce the flickering?

    Rosi,

    I got the example screen movie you sent showing it working fine on your end.  It turns out to be an issue with which version of OS 10 you are running.  I tried it on a machine with OS 10.5 and it works fine with the latest build you sent.  On machines with OS 10.3 it doesn't work.  OS 10.3 is over 3 years old, so don't worry about it anymore.  We should be good to go.

    Thanks for you help, I really appreciate it.  Your quick responses to the issues we are seeing is great.  I am really glad we chose your controls over ComponentArt.

    John
