为什么我的TextBlock / TextBox不应用基本样式的值？

问题描述

这是常见的，我写下面的东西像下面的样式数据输入表单，但我的问题是 TextBox 和 TextBlock 似乎没有实现在 BaseElementStyle 中的Setters。通常我需要分别定义它们。

It's not uncommon for me to write something like below for styling a data entry form, but my problem is that TextBox and TextBlock don't seem to implement the Setters that are in the BaseElementStyle. Usually I need to define them separately.

为什么是这样？有没有办法呢？

Why is this? And is there a way around it?

我猜这和它们通常用于其他控件模板的事实有关（例如TextBlock用于大多数控件

I am guessing it has to do with the fact they are usually used in other control templates (for example TextBlock is used in most controls and TextBox is used in DatePickers and ComboBoxes)

<Style x:Key="BaseElementStyle" TargetType="{x:Type FrameworkElement}">
    <Setter Property="Margin" Value="5" />
    <Setter Property="VerticalAlignment" Value="Center" />
</Style>
<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type Label}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type ComboBox}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type DatePicker}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type CheckBox}" BasedOn="{StaticResource BaseElementStyle}" />

推荐答案

我想建议两种可能的解决方法。看起来每个键和类型可以使用，但它们两个不能一起使用作为您的问题情况， x：Key =BaseElementStyleTargetType ={x：Type FrameworkElement}。

I would like to suggest the two possible workarounds. It seems that each of Key and Type can be used but both of them cannot be used together as your question case, x:Key="BaseElementStyle" TargetType="{x:Type FrameworkElement}".

1. 使用x：键

1. using x:Key

<Style x:Key="BaseElementStyle">
    <Setter Property="FrameworkElement.Margin" Value="5" />
    <Setter Property="FrameworkElement.VerticalAlignment" Value="Center" />
</Style>
<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type Label}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type ComboBox}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type DatePicker}" BasedOn="{StaticResource BaseElementStyle}" />
<Style TargetType="{x:Type CheckBox}" BasedOn="{StaticResource BaseElementStyle}" />

using x：Type

using x:Type

<Style TargetType="{x:Type FrameworkElement}">
    <Setter Property="Margin" Value="5" />
    <Setter Property="VerticalAlignment" Value="Center" />
</Style>
<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type Label}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type ComboBox}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type DatePicker}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type CheckBox}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
