Grouping Data
When looking at a grid with large amounts of data, it may be useful to group the data in the grid in order to sort and summarize the data based on particular values or groupings.
Dragging a column into the grouping area with cause the grid to be grouped based on the values in this column. Each unique value will become a separate grouping. Subtotals, counts or averages for any summarized columns in the grid will be reported in the group header.
NOTE: Not all grids have the grouping turned on in the default layout. If you do not see the grouping area at the top of the grid, toggle the feature under the Layout menu on the grid toolbar.
