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++;
}
Specify the type too:
<Trigger Property="TextBlock.IsMouseOver" Value="true">
<Setter Property="TextBlock.Foreground" Value="Gray" />
</Trigger>
This Way will help you:
<Style x:Key="SimpleLabel" TargetType="{x:Type Label}">
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Grid>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="{DynamicResource DisabledBackgroundBrush}" TargetName="Border"/>
<Setter Property="BorderBrush" Value="{DynamicResource DisabledBackgroundBrush}" TargetName="Border"/>
<Setter Property="Foreground" Value="{DynamicResource DisabledForegroundBrush}"/>
</Trigger>
<Trigger Property="TextBlock.IsMouseOver" Value="true">
<Setter Property="TextBlock.Foreground" Value="Gray" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
