Header Filter
Row headers can display Excel-style filter buttons. Clicking a filter button invokes the header filter popup window that enables you to apply filter criteria against this row.
The header filter supports the following modes:
ListandCheckedList— Available for all grid columns.DateRangeCalendarandDateRangePicker— Available for date columns only.NumericRangePicker— Available for numeric columns only.
The mode is specified at the row level using the SettingsHeaderFilter.Mode property.
