We are excited to be delivering the DXPivotGrid for Silverlight in the next upcoming release. The Silverlight version of the Pivot Grid is built using the same code base that DXPivotGrid for WPF is built on so we have a rich set of features and proven code base.
The screen shot below shows two versions of the DXPivotGrid for Silverlight, you can see many features including the ability to display the Prefilter so end users have a rich mechanism to display just the data they are interested in.
Let me know what you think and how you may use this new version of the Pivot Grid.
