我想从dependencyproperty 更改TextBlock 的前景色。
但我不改变文本块颜色。
我的代码中不知道这个问题。
如何使用触发器更改 TextBlock 的前景色？
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>
代码:
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++;
}
最佳答案
也指定类型:
<Trigger Property="TextBlock.IsMouseOver" Value="true">
<Setter Property="TextBlock.Foreground" Value="Gray" />
</Trigger>
