Question

我想做的事情看起来很简单，但是我花了很多时间没有任何结果.. = / 我想有一个WPF窗口，它带有一些具有某些属性的对象，并用它来弹出一些项目。具体而言，收到的对象如此定义：

public class ParameterForGraphicOptions
{
    public List<VariablesOptions> Variables { get; set; }
    public List<string> Simulations { get; set; }
    public List<string> ShowSimulations { get; set; }
}
public class VariablesOptions
{
    public string Name { get; set; }
    public bool Show { get; set; }
    public bool Average { get; set; }
    public bool Var { get; set; }
}

我想用Simulations和ShowSimulations填充2个ListBox，还有另一个列表连接到Variables Name和3复选框，当你更改列表中的选定项时，它们会改变它们的值.Windows代码（.cs）如下：

public GraphicOptions(ParameterForGraphicOptions pfgo) //NAME OF THE WINDOW
{
    InitializeComponent();                     //STD CALL
    this.DataContext = pfgo;                   //CONNECTING THE DATA CONTEXT
}

用于绑定的XAML代码是：

<Window x:Class="GUI.GraphicOptions"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="GraphicOptions" Height="450" Width="350">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="25" />
            <RowDefinition Height="150"/>
            <RowDefinition Height="25" />
            <RowDefinition Height="150"/>
            <RowDefinition Height="25"/>
            <RowDefinition Height="25" />
            <RowDefinition Height="11*" />
        </Grid.RowDefinitions>
        <Label Grid.Row="0">Simulation in Progress</Label>
        <Label Margin="188,0,0,0">Simulation to Show</Label>
        <ListBox Grid.Row="1" Height="150" HorizontalAlignment="Left" Name="Simulations" VerticalAlignment="Top" Width="140" />  
        <ListBox Grid.Row="1" Height="150" HorizontalAlignment="Left" Margin="188,0,0,0" Name="SimulationsToShow" VerticalAlignment="Top" Width="140" />
        <Label Grid.Row="2">Variables to Show</Label>

        <ListBox Grid.Column="0" Grid.Row="3" DataContext="{Binding Variables.Name}" Height="150" HorizontalAlignment="Left" Name="Variables" VerticalAlignment="Top" Width="140"  Grid.RowSpan="2" />
        <CheckBox Grid.Row="3" Content="Show" IsChecked="{Binding Variables.Show}"  Height="20" HorizontalAlignment="Left" Name="Show" VerticalAlignment="Top" Width="76" Margin="163,5,0,0" />
        <CheckBox Grid.Row="3" Content="Average" IsChecked="{Binding Variables.Average}"  Height="25"  HorizontalAlignment="Left" Name="Average" VerticalAlignment="Top" Width="76" Margin="174,54,0,0" Checked="Average_Checked" />
        <CheckBox Grid.Row="3" Content="Var" IsChecked="{Binding Variables.Var}" Height="25"  HorizontalAlignment="Left" Name="Variance" VerticalAlignment="Top" Width="76" Margin="163,31,0,0" />
        <CheckBox Content="Refresh Graphic During Computation" Grid.Row="5" Height="25" HorizontalAlignment="Left" Name="Continuos" VerticalAlignment="Top" Width="220" />
        <Button Content="Save" Grid.Row="5" Height="23" HorizontalAlignment="Left" Margin="253,1,0,0" Name="Save" VerticalAlignment="Top" Width="75" Click="Save_Click" />
        <Button Content="->" Grid.Row="1" Height="35" HorizontalAlignment="Left" Margin="145,30,0,0" Name="OneSimulation" VerticalAlignment="Top" Width="35" />
        <Button Content="=>" Grid.Row="1" Height="35" HorizontalAlignment="Left" Margin="145,65,0,0" Name="AllSimulation" VerticalAlignment="Top" Width="35" />
    </Grid>
</Window>

我尝试过多种方式，但总是只绑定一个项目，所以我无法理解这个库如何工作.. 非常感谢4所有人：P

问题是：我发布的代码中是否有任何错误？

P.S。：对不起我的英语：P

不要将单个控件绑定到多个项目。绑定一个选定的项目。

这是一个正确的解决方案：

<ListBox x:Name="vars" ItemsSource="{Binding Variables}" DisplayMemberPath="Name" />
<CheckBox IsChecked="{Binding SelectedItem.Show, ElementName=vars, Mode=TwoWay}" />
<CheckBox IsChecked="{Binding SelectedItem.Average, ElementName=vars, Mode=TwoWay}" />
<CheckBox IsChecked="{Binding SelectedItem.Var, ElementName=vars, Mode=TwoWay}" />

DataBinding在WPF GUI和几个ListBox / CheckBox之间
