Filter Button

• Jun 25, 2020

Filter buttons are displayed within column headers and can be clicked to activate filter dropdown lists. Such lists enable end-users to specify data filtering conditions.

The table below lists the main properties affecting element appearance.

Style	The GridOptionsView.HeaderFilterButtonShowMode property allows you to choose whether the filter buttons will be displayed as smart tags or in the traditional way - as regular buttons.
Appearance	GridViewAppearances.ColumnFilterButton, GridViewAppearances.ColumnFilterButtonActive Note: These settings are not in effect in the following cases: when the View is painted using a Windows XP or Office2003 theme (see the BaseView.PaintStyleName property); the filter buttons are painted as smart tags (see the GridOptionsView.HeaderFilterButtonShowMode property).
Custom Draw Event	GridView.CustomDrawColumnHeader
Icon and Icon Settings	Since all DevExpress controls use images and settings from the currently applied skin, to modify the button icon you need to create a custom Skin. You can do this in the WinForms Skin Editor. The name of a skin element responsible for the Filter Button is “Smart Filter” (the “Grid - Column Headers - Filtering” category).
Availability	A View’s GridOptionsCustomization.AllowFilter option and a column’s OptionsColumnFilter.AllowFilter option.
