I'm using the RadRotator to display some news headlines. I use the rotator inside a UserControl.
When I include the UserControl in a nromal aspx page, everything works perfect.
But if I use the userControl as a Sherepoint SmartPart, then I experience very slow performance with the rotator. I tried to open the page with iexplore and firefox, and in both cases the browser takes 60% of my dual core CPU while displaiyng the page.
Is there a workaround for this?
Please let me know how I can solve the performance problem.

Could you please test the standard asp:repeater control in such scenario? I am asking you this, because RadRotator uses the same databinding mechanism as the standard repeater and behaves just like one.
If you don't have such problems with the repeater control but you continue to experience them with RadRotator, please provide more information about your exact setup.
All the best,

Check out Telerik Trainer, the state of the art learning tool for Telerik products.
I use the RadRotator in the following setup:
telerik:RadRotator ID="RadRotator1" runat="server" RotatorType="AutomaticAdvance"
ScrollDirection="Up" ScrollDuration="4000" FrameDuration="0"
Height="335" ItemWidth="100%" Width="215" InitialItemIndex="-1" OnClientLoad="ScrollRotator"
I want to achieve something a continuous movement for the rotator.
In the item template I have just a link and two text fields which use databinding.
It still uses 60% of my cpu in firefox. In Iexplore it's ok, it uses only 10-15%.
The thing that uses the cpu excessively is the animation - while the page is shown, the rotator is continuously animated.
Could you, please, guide me to solve this problem?
Feel free to contact me or my manager, Olivier Mangelschots(firstname.lastname@example.org), for more details.
I would like to add another issue that I have.
When I use the UserControl containing the RadRotator as a SharePoint SmartPart, the page that contains the control reloads every 5 seconds.
Thank you for the additional information, however it is still not enough for us to provide you with an appropriate answer. Could you please confirm that you have tested your scenario with a standard repeater control instead of RadRotator? If you did, please let us know what the results were.
Also I would like to ask you to open a support ticket and send us the HTML dump of the page that is causing the problem. This could help us to track down the reason for the behavior that you experience.

Thanks for the quick reply.
I tested using a Repeater, and everything seems to be ok in this scenario.
But ofcourse, one thing is missing when using a Repeater: the animation.
And I believe this is what is causing the problem.
I will open a new support case and attach the html for the page.
