Remarks
To prohibit using pop-up filter menus and the filter panel, set the AllowFilter property to false. To override this setting for a particular column, use the TreeListColumn.OptionsFilter.AllowFilter property (see TreeListOptionsColumnFilter.AllowFilter).
If filtering is disabled for users, you can still apply filters in code:
- by setting the TreeList.ActiveFilterString and TreeList.ActiveFilterCriteria properties;
- by calling the TreeList.AddFilter method overloads;
- by handling the TreeList.FilterNode event.
