Property Value

Type	Default	Description
FilterPopupMode	**Default**	A FilterPopupMode value that specifies the display mode for the column’s filter dropdown list.

Available values:

Name	Description
Default	The actual display mode is determined by the TreeList’s OptionsFilter.ColumnFilterPopupMode (TreeListOptionsFilter.ColumnFilterPopupMode) property. If the TreeList’s OptionsFilter.ColumnFilterPopupMode property is set to Classic: for columns displaying date-time values, this option is equivalent to the Date option; for other columns, this option is equivalent to the List option. If the TreeList’s OptionsFilter.ColumnFilterPopupMode property is set to Default (which is the initial value): the column filter dropdown style is determined by the WindowsFormsSettings.ColumnFilterPopupMode global setting. If the WindowsFormsSettings.ColumnFilterPopupMode property is also set to Default (which is the initial value): the Excel filter dropdown style is applied.
List	The filter dropdown is represented as a regular list of filter items. Clicking an item invokes a corresponding action, and automatically closes the dropdown.
CheckedList	The filter dropdown is represented as a checked list of filter items. In this mode, an end-user can select more than one item simultaneously. When the dropdown window is closed by clicking the OK button, the control will display those records that contain the checked values.
Date	This mode is in effect for columns displaying date-time values. The filter dropdown contains a calendar, plus check boxes that allow used date intervals to be selected. If there is no underlying data that would fall into a specific date range, the corresponding check box is hidden.
Excel	The tabbed UI, inspired by MS Excel, that displays column values and provides filtering options most suitable for the column’s data type.
