  Android: the Maui FlexGrid control keeps its default colors (light) regardless the theme is changed from Light to Dark in the phone. How Can I fix this?
  
  Thanks,
  
  Louis

  Hi,

  C1 controls are independent of System Themes. You can apply AppThemeBinding accordingly to customize the view in Light or Dark mode.
  
  Please refer here: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/system-theme-changes?view=net-maui-7.0

  You can apply AppThemeBinding for Flexgrid too:

      <ContentPage.Resources>
          <!-- Dark Theme colors -->
          <Color x:Key="DarkRowBackGround">DarkGray</Color>
          <Color x:Key="DarkAltRowBackGround">LightGray</Color>
          <Color x:Key="DarkPrimaryColor">Black</Color>
          <Color x:Key="DarkForegroundColor">White</Color>
  
      </ContentPage.Resources>
      <StackLayout>
          <c1:FlexGrid x:Name="grid"
                       BackgroundColor="{AppThemeBinding Dark={StaticResource DarkPrimaryColor}}"
                       RowBackground="{AppThemeBinding Dark={StaticResource DarkRowBackGround}}"
                       AlternatingRowBackground="{AppThemeBinding Dark={StaticResource DarkAltRowBackGround}}"
                       RowForeground="{AppThemeBinding Dark={StaticResource DarkForegroundColor}}"
                       ColumnHeaderBackground="{AppThemeBinding Dark={StaticResource DarkPrimaryColor}}"
                       ColumnHeaderForeground="{AppThemeBinding Dark={StaticResource DarkForegroundColor}}"
                       />
      </StackLayout>
  

  Please refer the sample for full implementation: FlexGridMAUI.zip
  
  Refer the gif for the same:

  As compared to WPF or Winforms, we do not support Themes for C1 MAUI controls directly. However, we have raised an enhancement to support Themes.[Internal Tracking Id - C1XAML-31147]

  Best Regards,
