WPF resource not found
If I use the following in XAML I get an error:
<Style TargetType="TreeViewItem">
<Style.Triggers开发者_如何学JAVA>
<DataTrigger Binding="{Binding Selected}" Value="True">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightColor}}"/>
</DataTrigger>
</Style.Triggers>
</Style>
The error is:
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='#FF316AC5'
You meant HighlightColorKey
, not HighlightColor
. The key is used with DynamicResource
whereas the color is used only with {x:Static}
but won't be dynamic.
Looks like you were almost right, just the wrong keys!
<Style.Triggers>
<DataTrigger Binding="{Binding Selected}" Value="True">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
</DataTrigger>
</Style.Triggers>
