WPF：从code添加控件 [英] WPF: Add controls from code

问题描述

我已经习惯了Windows窗体而不是WPF。因为我认为WPF有我想在我的新项目中使用它很大的优势。

I'm used to Windows Forms but not to WPF. As I think that WPF has great advantages I'm trying to use it in my new projects.

我的问题是下一：
我有一个XML文件巫婆告诉我，我一定要添加到表单控件，但是这个XML可以改变，所以我需要：

My problem is the next: I have an Xml file witch tells me the controls I have to add to a form but this Xml could change so I need to:

1. 读取XML文件（解决了，没问题）


2. 创建与我已阅读数据的自定义WPF窗体。

这可能吗？或者我应该使用Windows窗体？

Is it possible? Or should I use Windows Forms?

推荐答案

是的，它是可能的。

WPF提供了无论是在XAML或code创建控件的几种方法。

WPF offers several ways of creating controls either in Xaml or in code.

有关你的情况，如果你需要动态地创建控件，你必须在code来创建它们。你可以创建你的控制，直接使用其构造为：

For your case if you need to dynamically create your controls, you'll have to create them in code. You can either create your control directly using their constructors as in:

        // Create a button.
        Button myButton= new Button();
        // Set properties.
        myButton.Content = "Click Me!";

        // Add created button to a previously created container.
        myStackPanel.Children.Add(myButton);

或者你可以创建你的控件作为一个字符串包含XAML和使用XamlReader来解析字符串，并创建所需的控制：

Or you could create your controls as a string containing xaml and use a XamlReader to parse the string and create the desired control:

        // Create a stringBuilder
        StringBuilder sb = new StringBuilder();

        // use xaml to declare a button as string containing xaml
        sb.Append(@"<Button xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' 
                            xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' ");
        sb.Append(@"Content='Click Me!' />");

        // Create a button using a XamlReader
        Button myButton = (Button)XamlReader.Parse(sb.ToString());

        // Add created button to previously created container.
        stackPanel.Children.Add(myButton);

现在您要使用这两种方法之一实际上取决于你。

Now for which one of the two methods you want to use really depends on you.
