我有一个像这样的XAML DataTemplate应用于ListBoxItems。注意底部附近的网格。我想要做的是根据文本的值更改绑定文本的颜色,如'Status:ERROR',其中'ERROR'为红色。
<DataTemplate x:Key="ItemTemplate">
<Border BorderBrush="Gray" BorderThickness="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="3*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Rectangle Grid.Row="0" Grid.Column="0">
<Rectangle.Fill>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Color="#FFA9A9A9" Offset="1.0"/>
<GradientStop Color="#FFF4F4F5" Offset="0.0"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<Label Content="{Binding Name}" FontSize="22" Grid.Row="0" Grid.Column="0" VerticalAlignment="Center"/>
<Rectangle Grid.Row="1" Grid.Column="0" Grid.RowSpan="3">
<Rectangle.Fill>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<GradientStop Color="#FFF0F0F1" Offset="1.0"/>
<GradientStop Color="#FFF4F4F5" Offset="0.0"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<Grid Grid.Row="1" Grid.Column="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label Content="Status:"/>
<Label Content="{Binding Status}" Grid.Column="1"/>
</Grid>
<Label Content="{Binding Bookmark}" ContentStringFormat="Last Bookmark: {0}" Grid.Row="3" Grid.Column="0"/>
</Grid>
</Border>
</DataTemplate>
如何从后面的代码(C#)更改绑定状态<Label>
中的文本文本的颜色?
(或者,如果不是来自代码,那么XAML中的状态如何?状态可以有3个文本值(排队,运行和错误),每个值都与指定的颜色(蓝色,绿色和红色)匹配)
答案 0 :(得分:0)
根据@SLaks提示,我能够得出完整的答案。这是给其他人的:
这:
<Grid Grid.Row="1" Grid.Column="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label Content="Status:"/>
<Label Content="{Binding Status}" Grid.Column="1"/>
</Grid>
成为这个:
<Grid Grid.Row="1" Grid.Column="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label Content="Status:"/>
<Label Content="{Binding Status}" Grid.Column="1">
<Label.Style>
<Style TargetType="Label">
<Style.Triggers>
<DataTrigger Binding="{Binding Status}" Value="RUNNING">
<Setter Property="Label.Foreground" Value="Green"></Setter>
</DataTrigger>
<DataTrigger Binding="{Binding Status}" Value="ERROR">
<Setter Property="Label.Foreground" Value="Red"></Setter>
</DataTrigger>
<DataTrigger Binding="{Binding Status}" Value="QUEUED">
<Setter Property="Label.Foreground" Value="Blue"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</Label.Style>
</Label>
</Grid>
