在WPF中将ComboBox绑定到XML [英] ComboBox Binding to XML in WPF

问题描述

我知道这个问题已经死了，但是我尝试了很多发现的建议答案，当我在VS2013中启动WPF时，组合框仍然没有出现。来了我有一个名为People.xml的XML文档，其格式如下...

I know this question has been asked to death, but I have tried lots of the suggested answers I have found and the Combo Box is still not populating when I start the WPF in VS2013. Here it goes. I have an XML document called People.xml that is formatted like so...

<?xml version="1.0" encoding="utf-8"?>
<People>
  <Person>
    <personName>John Doe</personName>
    <personEmail>[e-mail]</personEmail>
    <personReports>List of reports they get go here.</personReports>
</Person>

在应用程序的App.xml部分中，我将此作为资源：

In App.xml portion of the application I have this as a resource:

<XmlDataProvider x:Key="People" Source="\DataSources\People.xml" XPath="People" IsInitialLoadEnabled="True" />

然后，在组合框的XAML中，我将其列出为：

Then, in the XAML for the combo box, I have it listed as this:

<ComboBox x:Name="employeeNameBox" IsReadOnly="False" HorizontalAlignment="Left" IsEditable="True" ItemsSource="{Binding Source={StaticResource People}, XPath=./Person/personName}">

我要了解的是用XML中的所有personName元素填充组合框

What I am trying to get at is populate the combo box with all of the personName elements in the XML doc.

再次，我尝试了几种不同的方法来尝试加载此方法，并且组合框始终显示为空。一般来说，我对数据绑定结构和WPF还是比较陌生的，所以我能得到的任何帮助都会很棒。

Again, I have tried several different ways to try and get this to load, and the combo box always comes up empty. I am relatively new to the data binding structures and WPF's in general, so any help I could get would be great.

谢谢！

推荐答案

对我来说，最简单的方法是 XmlSerializer 。

As for me, simpliest way is XmlSerializer.

public class Person
{
    public string personName;
    public string personEmail;
    public string personReports;
}

public class People
{
    [XmlElement("Person")]
    public List<Person> Persons;
}

加载数据：

var people = (People)new XmlSerializer(typeof(People)).Deserialize(stream);
employeeNameBox.ItemsSource = people.Persons;

组合框代码：

<ComboBox x:Name="employeeNameBox" IsReadOnly="False" HorizontalAlignment="Left" IsEditable="True" DisplayMemberPath="personName">
