我试图将项目从我的组合框(绑定到模型对象的列表)传递到我的按钮。我的问题是,我是Caliburn.Micro+WPF新手,不太确定如何订阅/传递所需的值到我的按钮(比如将PropertyName的字符串发送到按钮(string PropertyName))

视图模型代码:

class ShellViewModel : Screen
{
    private DataModel _fileInFolder;
    private BindableCollection<DataModel> _data;

    public ShellViewModel()
    {
       // .GetData() preforms the objects'  initialization
        DataModel dataOutput = new DataModel();
        Data = new BindableCollection<DataModel>(dataOutput.GetData());
    }


    public BindableCollection<DataModel> Data 
    {
        get
        {
            return _data;
        }

        set
        {
            _data = value;
            NotifyOfPropertyChange(() => Data);
        }
    } 

    public DataModel FileInFolder
    {
        get { return _fileInFolder; }
        set 
        { 
            _fileInFolder = value;

            NotifyOfPropertyChange(() => FileInFolder);

        }
    }

   //This is where the items will be passed to.
  
  public void OpenFile()
  {
       
  }

}

{

公共ShellViewModel()
{
//.GetData()执行对象的初始化
DataModel dataOutput=新的DataModel();

}

}
}
XAML代码:

<Grid>
    <!-- Folders -->
    <ComboBox ItemsSource="{Binding Data}" SelectedItem="{Binding FileInFolder}"
     HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="250">
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Folders}"/>
            </DataTemplate>
        </ComboBox.ItemTemplate>
    </ComboBox>
    <!-- Files -->
    <ComboBox x:Name="FileInFolder_Files"
    HorizontalAlignment="Left" Margin="280,10,0,0" VerticalAlignment="Top" Width="250"/>
    <!-- Open File -->
    <Button x:Name="OpenFile" 
    Content="Open File" HorizontalAlignment="Left" Margin="560,10,0,0" VerticalAlignment="Top" Width="90">
       
    </Button>

</Grid>


抱歉,如果我的描述含糊不清/缺少更多说明,我是这里的新用户

FileInFolder是组合的选定项

OpenFile在同一个类中,因此可以引用FileInFolder

public void OpenFile()
{
     var whatever = FileInFolder.SomeProperty;
   // etc
}
您可能需要在那里进行一些空检查
