如何创建只存在于ResourceDictionary上下文中的样式

如何创建一个只存在于ResourceDictionary上下文中,而不存在于包含该ResourceDictionary的控件上下文中的样式?
例如,我希望能够有一个像这样的ResourceDictionary:
<!-- ControlTemplates.xaml -->
<ResourceDictionary>
<!-- Private Local styles used to set up the publicly usable templates -->
<Style x:Key="TextBoxes" TargetType="TextBox">
<Setter Property="TextWrapping" Value="Wrap" />
</Style>
<!-- End of Private Local Stuff -->
<!-- Public Dictionary Resources Follow -->
<ControlTemplate x:Key="CustomTextBox">
<TextBox Style="{StaticResource TextBoxes}" />
</ControlTemplate>
</ResourceDictionary>
然后在其他控件或窗口中,我希望能够输入:
<Window>
<Window.Resources>
<ResourceDictionary Source="ControlTemplates.xaml">
</Window.Resources>
<Grid>
<!-- This Should Work -->
<CustomControl Template="{StaticResources CustomTextBox}">
<!-- This Should NOT Work! -->
<TextBox Template="{StaticResources TextBoxes}">
</Grid>
</Window>
一种非常接近您正在寻找的方法是将"私有"样式从ControlTemplates.xaml
移动到自己的ResourceDictionary
,然后在controltemplate .xaml:
ControlTemplates.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<!-- By referencing the ResourceDictionary from within the ControlTemplate's
resources it will only be available for the ControlTemplate and not for those
who reference ControlTemplates.xaml -->
<ControlTemplate x:Key="CustomTextBox">
<ControlTemplate.Resources>
<ResourceDictionary Source="ControlTemplatePrivateStyles.xaml" />
</ControlTemplate.Resources>
<TextBox Style="{StaticResource TextBoxes}" Text="Some text" />
</ControlTemplate>
</ResourceDictionary>
ControlTemplatePrivateStyles.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="TextBoxes" TargetType="TextBox">
<Setter Property="TextWrapping" Value="Wrap" />
</Style>
</ResourceDictionary>
那么窗口的xaml将看起来像这样:
<Window x:Class="ResourceDictionaryPrivateStyle.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:ResourceDictionaryPrivateStyle="clr-namespace:ResourceDictionaryPrivateStyle"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary Source="ControlTemplates.xaml" />
</Window.Resources>
<StackPanel>
<!-- This works -->
<ResourceDictionaryPrivateStyle:CustomControl Template="{StaticResource CustomTextBox}" />
<!-- This does not work, unless you explicitly reference ControlTemplatesPrivateStyles.xaml here in the window-->
<TextBox Text="Text" Style="{StaticResource TextBoxes}" />
</StackPanel>
</Window>
这样你就不能使用"private"样式,除非你显式地引用该资源字典。它们不能仅仅通过引用ControlTemplates来访问。Xaml资源字典。
