Hi,
After update to today's release of Q2 2010, we're seeing the following binding expression error when the grid is loaded.
Our XAML does not do any binding to the ValidationTooltip's TooltipContent as the message states. We rolled back to Q1's SP2 release and the error goes away when rendering the same XAML.
Is this a known issue?
Thanks,
Carlos

Hi Carlos Santos,
It is known issue related to the data validation our controls support for Silverlight. There should be no problems running this code and no visual glitches will appear due to this error. Also we will fix this as soon as possible so hopefully fixes will be released with the next internal build. For now I would recommend you to just ignore these errors as they appear only in Debug mode in the Output window.
I am very sorry for the inconvenience.
All the best,

Thanks,
It'd be great if you could post when the internal build has this resolved. I agree that the errors can be ignored since they just go to the output window, but when there's a few rows in the grid, all the messages make it harder to spot all other messages not related to this issue.
Thanks again,
Carlos
