How to make a WPF resource be recalculated when a trigger's run?

问题 In short: I've got a Style . It uses TemplateBinding a fair bit to make it parametrized instead of repeating myself over and over again. However, when a trigger for that style gets used and a resource gets used in a setter in that trigger, it just doesn't show up! Not even the default value gets shown. Here's a small program that replicates this issue: TestDictionary.xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft

I want to change the color of a WPF control depending on the state of a bool, in this case the state of a checkbox. This works fine as long as I'm working with StaticResources: My control <TextBox Name="WarnStatusBox" TextWrapping="Wrap" Style="{DynamicResource StatusTextBox}" Width="72" Height="50" Background="{Binding ElementName=WarnStatusSource, Path=IsChecked, Converter={StaticResource BoolToWarningConverter}, ConverterParameter={RelativeSource self}}">Status</TextBox> My converter: [ValueConversion(typeof(bool), typeof(Brush))] public class BoolToWarningConverter : IValueConverter {

Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/> What I want : <Setter ... Value="{DynamicResource {x:Static MyColors.Color1}}"/> Resource Keys can be anything, so you can use a Color as a key and value at the same time: public static class MyColors { static MyColors() { App.Current.Resources.Add(MyHighlightColorKey, MyHighlightColorKey); } public static readonly Color MyHighlightColorKey = Color.FromArgb(255, 0, 88, 0); } The static
