Column headers can display Excel-style filter buttons. Clicking a filter button invokes the header filter popup window that allows you to apply filter criteria to this column.
The header filter can operate in one of four modes: List and CheckedList modes (for all grid columns); DateRangeCalendar and DateRangePicker modes (for date columns only).
The mode is specified at the column level using the GridDataColumnHeaderFilterSettings.Mode property.
Refer to the Header Filter topic for more information.
The table below lists the main members that affect element appearance and functionality.
