In this sample, you can view the raw items of any pivot table cell by double-clicking the cell. The drill-through dialog holds the row headers, column headers, and values information of the clicked cell. Initially drill-through information is displayed for bound fields and you can include the remaining raw items details using the column chooser option in the dialog. This feature can be enabled by setting the allowDrillThrough as true. Injecting Module: The pivot grid widget features are segregated into individual modules. To enable drill-through, inject the DrillThroughService module into the @NgModule.providers section.
