Question

我有一个字典集合，我需要将它绑定到Silverlight ListBox。我无法使用Key值绑定到ListBox。下面是示例代码..我得到空记录代码背后的字典..

Dictionary<DayOfWeek, List<Book>> bookItem = new Dictionary<DayOfWeek, List<Book>>();
<ListBox x:Name="ListValues" ItemsSource="{Binding bookItem}">

                                        <ListBox.ItemTemplate>
                                            <DataTemplate>
                                          <StackPanel Orientation="Horizontal">

                     <TextBlock  Text="{Binding BookName[Tuesday]}"></TextBlock>
                             <TextBlock Text="{Binding BookDesc[Tuesday]}"></TextBlock>
                                                </StackPanel>
                                            </DataTemplate>
                                        </ListBox.ItemTemplate>
                                    </ListBox>

IDictionary.GetEnumerator返回KeyValuePair<TKey, TValue>的集合。因此，为了绑定到您的对象，您需要使用KeyValuePair上的属性。以下是如何显示数据的示例。

<DataTemplate>
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
    </Grid>
    <!-- Display the day of week in the first column -->
    <TextBlock Text="{Binding Current.Key}"/>

    <!-- Display the books in the second column -->
    <GridView Grid.Column="1" ItemsSource="{Binding Current.Value}" />
</DataTemplate>
