Hi,
I'm using version 2010.2.827.1040 and I'm encountering a strange behavior when using the #DATAITEM functionality in the tooltip format. When the dataserie has more than 199 points the #DATAITEM is not "rendered", the tooltip is contains "#DATAITEM.MyProperty....". Is this somekind of limitation?
Regards,
Steven Hillaert

Hello Steven,
The reason for this issue is called Sampling. The Chart combines it's items to avoid unclear visual representation (2 or more items shown for a single pixel), so that they are limited to a certain number (200 by default). You can read more about Sampling here - http://www.telerik.com/help/silverlight/radchart-features-sampling.html.
To be able to show "#DATAITEM.MyProperty...." in Tooltip for > 200 items you should disable Sampling by setting SamplingTreshold to 0.
