我在资源文件中有style
:
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Colors.xaml"/>
</ResourceDictionary.MergedDictionaries>
<Style TargetType="TextBox" x:Key="StandardTextBox"/>
<Setter Property="Foreground" Value="{StaticResource Color1}"/>
</Style>
</ResourceDictionary>
(Colors.xaml包含我的brushes
)
我的代码使用style
:
ResourceDictionary TetxboxStyles = new ResourceDictionary();
TetxboxStyles.Source = (new Uri("TextboxStyles.xaml", UriKind.RelativeOrAbsolute));
Resources.MergedDictionaries.Add(TetxboxStyles);
tb_input.Style = (Style)Find("StandardTextBox");
这没有问题,但是当我通过代码而不是TextboxStyles-File动态添加Colors-Resource时它不起作用:
ResourceDictionary TetxboxStyles = new ResourceDictionary();
TetxboxStyles.Source = (new Uri("TextboxStyles.xaml", UriKind.RelativeOrAbsolute));
//Adding the Colors.xaml Resource
ResourceDictionary Colors = new ResourceDictionary();
brushes.Source = (new Uri("Colors.xaml", UriKind.RelativeOrAbsolute));
TetxboxStyles.MergedDictionaries.Add(Colors);
Resources.MergedDictionaries.Add(TetxboxStyles);
tb_input.Style = (Style)Find("StandardTextBox");
输出-错误:
System.Windows.Markup.XamlParseException
"{DependencyProperty.UnsetValue}"
答案 0 :(得分:0)
我将StaticResource
替换为DynamicResource
并且有效
