Hi Telerik,

We’re having a RadTileView control inside a RadSplit container. While loading the page containing these controls, we notice that CPU usage is hitting 100%. We stumbled upon this while investigating an intermittent WSOD issue. We were thinking if this possible performance issue (CPU usage 100%) could be the reason for WSOD. Could you please let us know if there is a fix for this performance issue? The sample code is placed below.

Thanks,

Sathya

Hello Sathya Prasaad,

The TileView used to have some bad performance problems, but with Q1.2011 (we've just released the official Beta) we've release entirely new TileView, which is performing times faster, it's also virtualized and is doing Render animations, instead of Layout ones. You can give a try with the new TileView. We'll release the official version in a few weeks.
Thank you for your feedback.

Kind regards,
Miro Miroslavov
