The table below lists the main properties affecting element appearance.
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.
Note: These settings are not in effect in the following cases:
Custom Draw Event
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).
