如何在 UWP C# 中将网格添加到 ControlTemplate

问题描述

我想在 UWP 应用程序中使用 C# 向 ControlTemplate 添加网格

I want add grid to ControlTemplate using C# in UWP application

例如我有如下 XAML 代码:

For example I have XAML code like:

<ControlTemplate TargetType="HyperlinkButton">
<Grid Name="RootGrid">
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup Name="CommonStates">
            <VisualState Name="Normal"/>
            <VisualState Name="PointerOver">
                <Storyboard>
                </Storyboard>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
    <ContentPresenter Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" Content="{TemplateBinding Content}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>

我想从 C# 中做到这一点，ControlTemplate 没有 Child 或 Children

And i want to do it from C# like, ControlTemplate not have Child or Children

Grid grid1 = new Grid();
ControlTemplate cTempl = new ControlTemplate();
cTempl.child.add(grid1);

推荐答案

我不确定您为什么需要更改后面的 ControlTemplate 代码，但不建议这样做.根据ControlTemplate 的说明 类:

I'm not sure why you need to change the ControlTemplate code behind, but this is not recommended. According to the remarks of the ControlTemplate class:

控件模板提供组成控件实例的视觉效果和部件，因为它出现在应用程序的 UI 中.在运行时，模板已被应用，因此所有从模板创建的部分现在都是控件的真正部分.

该模板已在运行时应用，在定义 ControlTemplate 时实际上只使用两个属性:TargetType 和隐式 XAML.如果您确实想将其设置为代码，您可以尝试使用 XamlReader 用于解析 XAML，例如:

The template has already be applied at run time and there are really only two properties you use when defining a ControlTemplate: the TargetType, and the implicit XAML. If you do want to set it code behind, you may try to use XamlReader for parsing XAML, for example:

const string xaml = "<ControlTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"><Rectangle Stroke=\"Red\" StrokeThickness=\"3\" /></ControlTemplate>";
ControlTemplate сt=(ControlTemplate)XamlReader.Load(xaml);

同样，不推荐这样做.想想你为什么需要这个功能.您可以直接在 XAML 中更改它，或创建自定义控件以使用 OnApplyTemplate 方法设置您自己的 ControlTemplate.

Again, this is not recommended. Think about why you need this feature. You could directly change it in XAML, or create a custom control to set your own ControlTemplate with OnApplyTemplate method.
