Problem
I want to change foreground color of a TextBlock from dependencyproperty. But I don't change textblock color. I don't know this problem in my code. How can I change the foreground color of a TextBlock with a Trigger? XAML: ``` <TextBlock Name="TestBlock" Text="Test color" > <TextBlock.Style> <Style TargetType="TextBlock"> <Style.Triggers> <Trigger Property ="IsMouseOver" Value="True"> <Setter Property= "Foreground" Value="Gray"/> </Trigger> <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="0"> <Setter Property="Foreground" Value="Red" /> </DataTrigger> <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="1"> <Setter Property="Foreground" Value="Blue" /> </DataTrigger> <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="2"> <Setter Property="Foreground" Value="Green" /> </DataTrigger> <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="3"> <Setter Property="Foreground" Value="Black" /> </DataTrigger> </Style.Triggers> </Style> </TextBlock.Style> </TextBlock> ``` CODE: ``` public static DependencyProperty TestColorModeProperty = DependencyProperty.Register("TestColorMode", typeof(int), typeof(UpdateProgressItem)); public int TestColorMode { get { return (int)GetValue(TestColorModeProperty); } set { SetValue(TestColorModeProperty, value); } } .... private void button1_Click(object sender, RoutedEventArgs e) { TestColorMode++; } ```
