Hi Andrew,
Thanks for using Syncfusion products.
In Silverlight GridDataControl there is no support for ITypedList and IBindingList Interface. There is a mistake in our online Document. We will correct this mistake, in our upcoming volume release of Volume 2. We will update you once we change the document.
Virtual Grid Control is the Cell Based control. Virtual Grid is mainly used for performance oriented application like trading etc. Here there is no support for Filtering, Sorting etc.
But you can perform Filtering, Sorting etc in GridDataControl, which is databound control.
Regarding Dynamic data, we are having the sample in the dashboard itself, please find the sample in the below location,
Sample: < $Installation-directory\EssentialStudio\9.1.0.20\WPF\Grid.WPF\Samples\3.5\GridDataControl\DataBinding\Dynamic Objects Demo\CS>
Regarding WCF RIA services, we have attached the sample for your reference, please find the sample in the below location,
