我正在使用XAML获取每个包含属性列表的产品列表。当我输入静态文本时,我有XAML功能,但是当我尝试使用对象属性时,没有任何显示。
这是我的XAML:
<ListView ItemsSource="{Binding Products}">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Name}" FontSize="32" Margin="5" />
<GridView Grid.Column="1" ItemsSource="{Binding Attributes}">
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="HorizontalAlignment" Value="Stretch"/>
</Style>
</GridView.ItemContainerStyle>
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Key}" Foreground="White" Height="Auto"/>
<TextBlock Text="{Binding Value}" Foreground="White" Height="Auto"/>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
<Grid Grid.Column="2">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Text="Here is some selling point about product 1." FontSize="14" Margin="5" />
<StackPanel Grid.Row="1" Orientation="Horizontal">
<TextBlock Margin="5" FontSize="14" Text="1/4 oz: $150" />
<TextBlock Margin="5" FontSize="14" Text="1/2 oz: $250" />
<TextBlock Margin="5" FontSize="14" Text="1 oz: $450" />
</StackPanel>
</Grid>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
<Style TargetType="ListView">
<Setter Property="HorizontalAlignment" Value="Stretch"/>
</Style>
</ListView>
这是我的对象定义:
public class Product
{
public string Name { get; set; }
public string SellingPoint { get; set; }
public List<KeyValuePair<string, string>> Attributes { get; set; }
public Scale Scale { get; set; }
public UnitOfMeasure UoM { get; set; }
}
我最初只是尝试使用字典作为属性,但发现字典没有XAML绑定。另一篇文章建议我使用List&gt;代替。我知道我绑定到属性很好,因为当我使用静态文本时,为我创建的模拟对象显示正确数量的属性(每个产品2个KeyValuePairs)。
答案 0 :(得分:2)
也许这不是你要求的,但你可以为属性创建自己的类,例如:
public class Attribute
{
public string Name {get;set;}
public string Value {get;set;}
}
然后,您可以将List<Attribute>
用作Product
类中的属性,而不是List<KeyValuePair<string, string>>
。
您的XAML将如下所示:
<GridView Grid.Column="1" ItemsSource="{Binding Attributes}">
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="HorizontalAlignment" Value="Stretch"/>
</Style>
</GridView.ItemContainerStyle>
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}" Foreground="White" Height="Auto"/>
<TextBlock Text="{Binding Value}" Foreground="White" Height="Auto"/>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
