Hello
I have upgraded from classic PanelBar to PanelBar for asp.net ajax. My panelbar is populated server side and seems to be served as proper html with all correct css classes, but in IE7 the PanelBar is first rendered as a simple un-styled html list, and then quickly (<1 second) re-rendered with correct style (I have tried Vista, Black etc). In firefox this does not happen.
The panelbar is very simple, no postbacks, no ajax, just items with links and default collapse/expand behavior.
I suspect the "new" asp.net ajax style init code that looks like this:
Sys.Application.add_init(function() {
$create(Telerik.Web.UI.RadPanelBar,.... etc
Sys.Application.initialize();
What can I do to get the "old" quick no-nonsense behavior back?

Hi Christian Jensen,
We cannot reproduce such behavior in our online demos. Are you doing anything different?

Hello
I have a "shared" ComponentArt calendar control (used in datepicker popups) on all pages (actually on the master page) because I do a lot of partial page updates and need to know that there is a calendar control on the page.
If I remove that control the flickering stops (or at least is so fast that it can be accepted (there is still a "white flash" of un-styled rendering))
If I use the radcalendar DatePicker(with its nice build-in shared calendar capability) instead of the ComponentArt one, can I count on that the fickering goes away?

Hi Christian Jensen,
There are no known "flickering" issues caused by RadCalendar. You can give it a try. Also make sure your <head> tag has its runat="server" attribute set. If it does CSS files will be registered in the <head> tag which would eliminate any potential flickering due to delayed CSS loading/

Thank you, flickering is gone.
My head tag had was not a server tag, so the rad controls could not "register css reference".
I added runat="server" and a RadCodeBlock around my existing script tags in the head. (nice with a help text in the execption message!)
