This demo shows how to create a cross-tab report. To accomplish this, use the XRPivotGrid control (which can be added to any report band) and then bind it to a report's (or its own) datasource to display data in a matrix form.
Note that the XRPivotGrid control is shipped within XtraReports. So when you purchase XtraReports, you can create cross-tabs in your reports. However, to be able to add pivot grids to your Windows Forms and ASP.NET applications, you need to purchase the XtraPivotGrid Suite separately.
