C# WPF基于同一列表的两个组合框

我对使用WPF相当陌生，我希望实现以下简单场景：

我有两个组合框，cmbSite和cmbLogFiles，我有一个

列表

，其定义如下：

class LogFileDirectory 
{
    public List<System.IO.FileInfo> Files { get; private set; }
    public string Name { get; private set; }
    public string Path { get; private set; }

    private LogFileDirectory() { }
    public LogFileDirectory(string name, string path)
    {
        this.Name = name;
        this.Path = path;
        this.Files = new List<System.IO.FileInfo>();
        if (System.IO.Directory.Exists(this.Path))
        {
            foreach (string file in System.IO.Directory.GetFiles(this.Path, "*.log", System.IO.SearchOption.TopDirectoryOnly))
                this.Files.Add(new System.IO.FileInfo(file));
        }

    }
}

我希望cmbLogFiles绑定到当前所选cmbSite的同一

列表

上的文件属性，并过滤到cmbSite当前所选值的条目LogFileDirectory对象，但我真的不太确定如何在不在cmbSite的ClickEvent处理程序中写入代码的情况下执行此操作（根据我的WPF研究，这似乎是错误的方法）并将cmbLogFiles重新绑定到select cmbSite LogFileDirectory。

根据@Chris在上面的评论中指出的线程，解决方法很简单

<ComboBox Name="cmbLogFiles" Width="140" ItemsSource="{Binding SelectedItem.Files, ElementName=cmbSite}" />

然后是解析器窗口的后续XAML：

<Window x:Class="Zapora.UI.Parser"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Log File Parser" Height="350" Width="525">
    <StackPanel Orientation="Horizontal" Height="26" VerticalAlignment="Top">
        <Label Content="Web Site:"/>
        <ComboBox  Name="cmbSite" Width="180" ItemsSource="{Binding WebServerLogFileDirectories}" DisplayMemberPath="Name" SelectedValuePath="Path"/>
        <Label Content="Files Available:"/>
        <ComboBox Name="cmbLogFiles" Width="140" ItemsSource="{Binding SelectedItem.Files, ElementName=cmbSite}" />
    </StackPanel>
</Window>

这应该让你开始：@Chris这比我想象的简单多了。谢谢你的提示。

parserView = new Parser();
parserView.DataContext = new LogFileInfo("deathstar");

<Window x:Class="Zapora.UI.Parser"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Log File Parser" Height="350" Width="525">
    <StackPanel Orientation="Horizontal" Height="26" VerticalAlignment="Top">
        <Label Content="Web Site:"/>
        <ComboBox  Name="cmbSite" Width="180" ItemsSource="{Binding WebServerLogFileDirectories}" DisplayMemberPath="Name" SelectedValuePath="Path"/>
        <Label Content="Files Available:"/>
        <ComboBox Name="cmbLogFiles" Width="140" ItemsSource="{Binding SelectedItem.Files, ElementName=cmbSite}" />
    </StackPanel>
</Window>
