XAML等效代码 [英] XAML equivalent code

问题描述

我的标签类型的用户控件中有一个属性.
问题是，如果我想从主机应用程序xaml设置此标签的属性值，那么如何实现它.无法找到正确的语法.

Hi,
I have a property in my user control of type Label.
Problem is if I want to set the value of the properties of this label from a host application xaml then how can it be achieved. Not able to find the correct syntax.

public Label TestProperty
        {
            get { return lblValue; }
            set { lblValue = value; }
        }

在后面的代码中，我们可以将该值作为
访问

in the code behind we can access this value as

object.TestProperty.FontSize = 25;

如何从主机应用程序xaml中设置相同的值.

how can I set the same value from the host application xaml.

推荐答案

您应将其实现为 ^ ]

You should implement this as a Dependency Property[^]

我相信以下内容会有所帮助.我相信您需要的是DependencyObject.然后DependencyObject 可以具有DependencyProperties:

I beleive the following will help. What you need I beleive is a DependencyObject. The DependencyObject can then have DependencyProperties:

I looked into this before, and could not figure how to solve your problem. I just bypassed the problem by creating specific properties.
