Hi Charlie,

The short answer here is the xamGrid is used to show the data of any IEnumerable. In other words tabular data. In the terms of SQL you can use the control to show the contents of a table.

The xamPivotGrid is a control that is showing analyzed data. In terms of SQL you can use this control to show data from Analysis services. Attaching different datasources you can use the control for reading data from MSAS, Oracle, SAP or to analyse your tabular data and convert it to OLAP with using the FlatDataSource

The long answer you can find in the documentation of these controls:
