Still searching for the proper way to pull a color for the theme - xaml syntax

That worked, thanks!

To ask a followup, (and if gets out of scope for DevExpresses responsibility), when I use VS2019 Dark and VS2019 light, the title bar forecolor is white in both. However, when I use this key:

<Setter Property="Foreground" Value="{dxi:ThemeResource {dxt:ThemedWindowThemeKey ResourceKey=WindowTitleForeground}}" />

It renders black?

Hello,

Thank you for the update.

When I tried your code snippet in a sample project, the element that uses the theme resource changes according to the theme, and the title bar foreground changes too. See the attached project and screencast.

Could you elaborate on your ultimate goal? In addition, please share a sample project to illustrate your current implementation. This way, we will be in a better position to find a suitable solution.

I look forward to your response.

Regards,
Marc

Hi,

To start, if you think of any of my strategy or plans are ill-informed or dumb, please let me know :) I am trying to do the best I can to both learn wpf (I am a veteran winforms dev). I am hoping ofr suggestions

I am leading a UI team in create a suite of applications. As part of that, we want to set several visual styles and themes to maintain consistency across our products.

1. We have settled on vs2019 light\dark as our base theme. It is set like at application startup (or when you toggle light\dark modes

C#
ApplicationThemeHelper.ApplicationThemeName = Theme.VS2019DarkName;

2. We are using styles to customize our control (slightly) on top of that. For instance, we have a button style that adds 5px rounded corners. We have a style for GroupBoxes that round the corners, increase the font size, etc.
3. Since we're using FontAwesome as our icon library (this is outside of my control), we are using those for icon glyphs in many locations. For example, here is a FontAwesome remove and browse button. In my opening post, these are the buttons I am referring to. I'd like to say "The remove button is the same color gray that devex uses as the X when you add a 'clear' button inside a buttonedit.
   

I suppose I could just hard-code the color values, but that seems less responsible (in case we ever want to change our theme). Additionally, I don't know how to (in xaml) apply different styles based off my theme.

If this information isn't enough, i can provide a smaller sample. I'm doing some weekend work, and don't wanna do it at the moment unless what i've provided isn't useful

Here's some example styles i've created so far

XAML
<Style
    x:Key="StyleCheckEdit"
    BasedOn="{StaticResource _StyleEditorBase}"
    TargetType="dxe:CheckEdit">
    <Setter Property="HorizontalAlignment" Value="Left" />
 </Style>

 <Style
    x:Key="StyleDateEdit"
    BasedOn="{StaticResource _StyleEditorBase}"
    TargetType="dxe:DateEdit">
    <Setter Property="Mask" Value="G" />
    <Setter Property="MaskUseAsDisplayFormat" Value="True" />
    <Setter Property="MinValue" Value="1900-01-01" />
    <Setter Property="MaxValue" Value="2100-01-01" />
 </Style>

 <Style
    x:Key="StyleDateAndTimeEdit"
    BasedOn="{StaticResource StyleDateEdit}"
    TargetType="dxe:DateEdit">
    <Setter Property="StyleSettings">
       <Setter.Value>
          <dxe:DateEditNavigatorWithTimePickerStyleSettings />
       </Setter.Value>
    </Setter>
 </Style>

 <Style x:Key="StyleHorizontalRule" TargetType="Rectangle">
    <Setter Property="Height" Value="1" />
    <Setter Property="VerticalAlignment" Value="Center" />
    <!--  Dark Gray  -->
    <Setter Property="Fill" Value="{dxi:ThemeResource {dxt:ThemedWindowThemeKey ResourceKey=WindowActiveContentBorderBrush}}" />
    <Setter Property="Margin" Value="{StaticResource LongLeftRightMargin}" />
 </Style>
