Using the context menu
The context menu of the grid is aimed at facilitating your work with data: you can perform a variety of operations using the context menu items.
Right-click the grid to open the context menu, and select the Show Group Box item if you wish to group the grid data, or the Print Grid item to activate the Print Preview mode.
If necessary, you can select the Column Summary... context menu item to open the Column Summary dialog which allows you to view and edit the summary for each particular column.
