Header Filter

• Jul 27, 2022

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 are available for all grid columns; DateRangeCalendar and DateRangePicker modes are available for date columns only, NumericRangePicker mode is available for numeric columns only.

The mode is specified at the column level using the SettingsHeaderFilter.Mode property.

Refer to the Header Filter topic for more information.
