Public ReadOnly Property GroupByBox As GroupByBox
public GroupByBox GroupByBox {get;}
Remarks

The GroupBy Box is an interface element that gives you a way to dynamically group row data for display. When the GroupBy Box is visible, you can drag column headers into it using the mouse. The data will then be grouped according to the field you have specified. The grid creates a series of GroupBy rows whihc serve to aggregate data that has a common field value. You can then expand or collapse the GroupBy row to display or hide the data for a particular value.

For example, suppose you have a band in the grid that displays address information, including a field for City. If you drag the header of the City column into the GroupBy box, the grid will display a GroupBy row for every city that occurs in the rows of the band. You can expand the GroupBy row for a particular city to see all the data that relates to that city (i.e. all the data that has the name of the chosen city specified in its City field.)

The GroupBy Box object supports properties that give you control over the look of the GroupBy Box interface element (including an Appearance property.)

Example
Following code configures the look of group-by-box in the ultragrid. Group-by-box is where the user can drag and drop columns to group rows by those columns.
