是否可以扩展xaml setter？ [英] Is it possible to expand a xaml setter?

问题描述

大家好，



xaml样式是否可以从具有settertemplate的样式继承，继承所有现有触发器并将其扩展为另一个触发器？



示例样式：

 <  样式    x：键 < span class =code-keyword> =  BigButton    TargetType   =   {x：Type   RadioButton} >  
 <   Setter    属性  = 模板 >  
 <   Setter.Value  >  
 <   ControlTemplate     TargetType   =  {x：输入RadioButton} >  
 <   ControLTemplate.Triggers  >  
 <  触发器   属性  =  IsMouseOver   值  =  true >  
 <   Setter    属性  = 不透明度   值  =  1  /  >  
 <   / Trigger  >  
 <  触发   属性  =  IsPressed   值  =  true >  
 <   Setter    属性  = 背景   值  = 红色  /  >  
 <   / Trigger  >  
 <   / ControlTemplate.Triggers  >  
 <   / ControlTemplate  >  
 <   / Setter.Value  >  
 <   / Style  >  

我的大多数按钮都有这两个触发器的样式。

现在问我的问题。

如果我有以下新风格：

 <  样式    x：键  =  BigButton    TargetType   =   {x：Type   RadioButton}   基于   =  {StaticResource BigButton} >  
 <  < span class =code-leadattribute> Setter     Property   = 模板 >  
 <   Setter.Value  >  
 <   ControlTemplate     TargetType   =   {x：类型  RadioButton} >  
 <   ControlTemplate.Triggers  >  
 <  触发器   属性  =  IsEnabled   值  =  true < span class =code-keyword>>  
 <   Setter    属性  = 背景   值  = 白色  /  >  
 <   /触发 >  
 <   /ControlTemplate.Triggers  >  
 <   / ControlTemplate  >  
 <   / Setter.Value  >  
 <   / Style  >  

使用这种风格它会覆盖以前的模板设定器。

所以我的问题是：

有没有办法不覆盖以前的模板设定器而只是在新款式中添加触发器？



我希望你能提供帮助我。

解决方案

我认为这是不可能的。您可以尝试将其他触发器添加到Style.Triggers中，并且根本不要触摸Template属性。在你的样本中，它应该可以工作。

Hello everyone,

Is it possible for a xaml style to inherit from a style with the setter "template", inherit all existing triggers AND expand it with another trigger?

Example Style:

<Style x:Key="BigButton" TargetType={x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<ControLTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Opacity" Value="1"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Style>

Most of my Buttons have style with these two triggers.
So now to my question.
If I have following new Style:

<Style x:Key="BigButton" TargetType={x:Type RadioButton}" based on="{StaticResource BigButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType={x:Type RadioButton}">
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="true">
<Setter Property="Background" Value="White"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Style>

With this style it overwrites the previous Template Setter.
So my question is:
Is there a way to NOT overwrite the previous Template Setter and only add the trigger in the new Style?

I hope you can help me.
If there are missing information please write it

Greetings
Richard

Tried to get the triggers out of the controltemplate

解决方案

I think it's impossible. You can try to put additional triggers into Style.Triggers and don't touch Template property at all. In your sample it should work.
