Hi Tariq,
We are working out the logics in the Grid Data Control for implementing raw Collection View Grouping. Work is under progress, and I will have you notified once we have this.
For using the Filters, Please download the latest version from the following link,
http://www.syncfusion.com/downloads/latestversion/default.aspxWe currently support simple Excel-like Combo filters.
Syncfusion does not make use of any of the N-Math libraries. CenterSpace Software is a partner that we list on this web page, but we do not use their software in the Syncfusion libraries that we ship.

Thanks,
Fahad
