Question

我正在创建一个WPF应用程序，允许用户进行测验然后提交他们的答案并在另一个页面/ xaml / window中检查结果。我的第一页显示了ListView中的问题列表和单个“提交”按钮。我的ListView中的问题是从我创建的名为“Question”的类中绑定的。它有7个属性，即：number，problem，choice1，choice2，choice3，choice4和correct_answer。 ListView中不显示属性“correct_answer”。如果用户提交他们的答案并查看结果，我希望能够在另一个包含在TreeView中的xaml中显示具有正确答案的相同问题列表。我的第二页显示了测验的分数和结果。喜欢检查正确答案的用户可以扩展TreeView。

QuizWindow.xaml

    <ListView Grid.Row="2" Name="list_question" ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"></RowDefinition>
                        <RowDefinition Height="Auto"></RowDefinition>
                        <RowDefinition Height="Auto"></RowDefinition>
                    </Grid.RowDefinitions>

                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto"></ColumnDefinition>
                        <ColumnDefinition Width="Auto"></ColumnDefinition>
                    </Grid.ColumnDefinitions>

                    <Label Content="{Binding number}"></Label>
                    <Label Grid.Column="1" Content="{Binding problem}"></Label>

                    <RadioButton Grid.Row="1" Content="{Binding choice1}"></RadioButton>
                    <RadioButton Grid.Row="2" Content="{Binding choice2}"></RadioButton>
                    <RadioButton Grid.Row="1" Grid.Column="1" Content="{Binding choice3}"></RadioButton>
                    <RadioButton Grid.Row="2" Grid.Column="1" Content="{Binding choice4}"></RadioButton>
                </Grid>   
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

    <Button Grid.Row="3" Content="Submit" Name="btn_submit" Click="btn_submit_Click"></Button>

按钮点击事件以查看考试结果。 QuizWindow.xaml.cs

    private void btn_submit_Click(object sender, RoutedEventArgs e)
    {
        ResultWindow resultWindow = new ResultWindow();
        resultWindow.Show();
        this.Close();
    }

ResultWindow.xaml

    <TreeView Grid.Row="2" ItemsSource="{Binding}">
        <TreeViewItem Header="Review">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"></RowDefinition>
                    <RowDefinition Height="Auto"></RowDefinition>
                    <RowDefinition Height="Auto"></RowDefinition>
                </Grid.RowDefinitions>

                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"></ColumnDefinition>
                    <ColumnDefinition Width="Auto"></ColumnDefinition>
                </Grid.ColumnDefinitions>

                <Label Content="{Binding number}"></Label>
                <Label Grid.Column="1" Content="{Binding problem}"></Label>

                <RadioButton Grid.Row="1" Content="{Binding choice1}"></RadioButton>
                <RadioButton Grid.Row="2" Content="{Binding choice2}"></RadioButton>
                <RadioButton Grid.Row="1" Grid.Column="1" Content="{Binding choice3}"></RadioButton>
                <RadioButton Grid.Row="2" Grid.Column="1" Content="{Binding choice4}"></RadioButton>
            </Grid>
        </TreeViewItem>
    </TreeView>

不确定这是否是最佳解决方案，但您可以传递列表＆lt;＆gt;进入结果窗口的构造函数

在QuizWindow.xaml.cs

中

private void btn_submit_Click(object sender, RoutedEventArgs e)
{
    ResultWindow resultWindow = new ResultWindow(/*pass list in here*/);
    resultWindow.Show();
    this.Close();
}

ResultWindow.xaml.cs中的

（伪代码）

class ResultsWindow : Window
{

public ResultWindow(list<> answers)
{
    InitializeComponent();             

    //note: in resultwindow.xaml add name = "some_name" to treeview
    some_name.datacontext = answers_list;       

}

修改

MainWindow.xaml中的

<Window x:Class="passlist.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <StackPanel> <Button Content="pass" Click="Button_Click"/> <ListBox Name="listbox1" ItemsSource="{Binding}"/> </StackPanel> </Grid> </Window>
MainWindow.xaml.cs中的

/// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { List<string> strings; public MainWindow() { InitializeComponent(); strings = new List<string>(); strings.Add("this"); strings.Add("that"); listbox1.DataContext = strings; } private void Button_Click(object sender, RoutedEventArgs e) { passto pt = new passto(strings); if (!pt.ShowDialog() ?? false) { MessageBox.Show("woohooo"); } } }

在passto.xaml
中
<Window x:Class="passlist.passto" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="passto" Height="300" Width="300"> <Grid> <ListBox Name="passlist" ItemsSource="{Binding}"/> </Grid> </Window>

在passto.xaml.cs
中
/// <summary> /// Interaction logic for passto.xaml /// </summary> public partial class passto : Window { public passto(List<string> plist) { InitializeComponent(); passlist.DataContext = plist; } }

此代码直接从我用来测试答案的项目中复制。
