Column headers can display Excel-style filter buttons. Clicking a filter button invokes the header filter popup window, which enables you to apply filter criteria against this column.
The header filter can operate in one of four modes: List and CheckedList modes are available for all grid columns; DateRangeCalendar and DateRangePicker modes are available for date columns only.
Use the GridDataColumnHeaderFilterSettings.Mode property to specify the mode at the column level.
Refer to the following topic for more information: Header Filter.
