[英]Changing colour of text in a textblock via a trigger
Here is my Xaml 这是我的Xaml
<Window.Resources>
<sampleData:MainWindow x:Key="DataSource"/>
<DataTemplate x:Key="bobReferencer">
<TextBlock Text="{Binding Name}" >
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding HasErrors}" Value="true">
//what goes in here?
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
</DataTemplate>
</Window.Resources>
Codebehind (the one xaml references) 代码隐藏(一个XAML参考)
public class bob
{
public string Name
{
get;
set;
}
public bool HasErrors
{
get;
set;
}
}
Basically what i want to do is if the HasErrors is true then i want the Name to appear in Red via the trigger. 基本上我想做的是,如果HasErrors为true,那么我希望名称通过触发器以红色显示。 But my xaml is not properly formed.
但是我的xaml格式不正确。 Any suggestions on this?
有什么建议吗? I also looked into this link but didn't help much.
我也研究了此链接,但并没有太大帮助。
How can I change the Foreground color of a TextBlock with a Trigger? 如何使用触发器更改TextBlock的前景颜色?
You were almost there.. 你快到了..
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding HasErrors}" Value="true">
<Setter Property="Foreground" Value="Red"/>
</DataTrigger>
</Style.Triggers>
</Style>
在DataTrigger中添加设置器
<Setter Property="Foreground" Value="Red"/>
