如何在 UWP C# 中将网格添加到 ControlTemplate [英] How to Add Grid to ControlTemplate in UWP C#

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.

Control templates provide the visuals and parts that make up an instance of a control as it appears in an app's UI. At run time, the template has already been applied, and so all the parts that were created out of the template are now truly parts of the control.

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.
