An implicit style could be added: <Style TargetType="telerik:FilteringControl" BasedOn="{StaticResource FilteringControlStyle}"> <Setter Property="Background" Value="{telerik:FluentResource ResourceKey=AlternativeBrush}" /> </Style>
As for the RadGlyph's properties, they are indeed Dependency Properties, so the warnings should not prevent it from working. However, we will investigate it further.
The fix for the backgrounds of the FilteringControls in RadGridView and RadVirtualGrid is available with the 2018 SP2.
I saw something that this was fixed, any estimate when it will be released? And as a Service Pack or Hot fix?
We don't use the implicit themes. It appears that not all the implicit theme files work. For instance, whenever a file has a RadGlyphStyle, it doesn't like the: <Setter Property="Font" Value="TelerikWebUI"/> <Setter Property="FontSize" Value="16"/> <Setter Property="VerticalAlignment" Value="Center"/> <Setter Property="HorizontalAlignment" Value="Center"/> It says that they are not dependency properties....
