Hello,

This video features the newly introduce (in .NET SP1) EntityDataSource declarative datasource control. I played a bit with the control against UltraWebGrid and indeed, currently we do not support it out of the box.

I played a bit with the new control and managed to make UltraWebGrid and EntityDataSource play nicely, you just need to disable to AllowPage and AllowSort properties of the EntityDataSource. This could either be a problem in the grid or most probably it is just me still trying to figure out how EntityDataSource works. In any case, I will talk to the development team and we willl make sure we fully support that.

Here is my code - is this applicable in your case?
