WPF的模版

此例子来自《深入浅出WPF》，刘铁猛。

VS2010

源码1：不使用Bingding

源码2：使用Binding

下面展示一些代码：

主窗体XAML代码：

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="350" Width="623" ResizeMode="NoResize">
    <Window.Resources>
        <local:AutomakerToLogoPathConverter x:Key="a2l"></local:AutomakerToLogoPathConverter>
        <local:NameToPhotoPathConverter x:Key="n2p"></local:NameToPhotoPathConverter>
        
        <DataTemplate x:Key="carDetailViewTemplate">
            <Border BorderBrush="Black" BorderThickness="1" CornerRadius="6">
                <StackPanel Margin="5">
                    <Image Width="400" Height="250" Source="{Binding Name,Converter={StaticResource n2p}}"></Image>
                    <StackPanel Orientation="Horizontal" Margin="5,0">
                        <TextBlock Text="Name:" FontWeight="Bold" FontSize="20"></TextBlock>
                        <TextBlock Text="{Binding Name}" FontSize="20" Margin="5,0"></TextBlock>
                    </StackPanel>
                    <StackPanel Orientation="Horizontal" Margin="5,0">
                        <TextBlock Text="Automaker:" FontWeight="Bold"></TextBlock>
                        <TextBlock Text="{Binding Automaker}" Margin="5,0"></TextBlock>
                        <TextBlock Text="Year:" FontWeight="Bold"></TextBlock>
                        <TextBlock Text="{Binding Year}" Margin="5,0"></TextBlock>
                        <TextBlock Text="Top Speed:" FontWeight="Bold"></TextBlock>
                        <TextBlock Text="{Binding TopSpeed}" Margin="5,0"></TextBlock>
                    </StackPanel>
                </StackPanel>
            </Border>
        </DataTemplate>
        <DataTemplate x:Key="carListItemViewTemplate">
            <Grid Margin="2">
                <StackPanel Orientation="Horizontal">
                    <Image Source="{Binding Automaker,Converter={StaticResource a2l}}" Grid.RowSpan="3" Width="64" Height="64"></Image>
                    <StackPanel Margin="5,10">
                        <TextBlock Text="{Binding Name}" FontSize="16" FontWeight="Bold"></TextBlock>
                        <TextBlock Text="{Binding Year}" FontSize="14"></TextBlock>
                    </StackPanel>
                </StackPanel>
            </Grid>
        </DataTemplate>
    </Window.Resources>
    <StackPanel Orientation="Horizontal" Margin="5">
        <UserControl ContentTemplate="{StaticResource carDetailViewTemplate}" Content="{Binding SelectedItem,ElementName=listBoxCars}"></UserControl>
        <ListBox x:Name="listBoxCars" Width="180" Margin="5,0" ItemTemplate="{StaticResource carListItemViewTemplate}"></ListBox>
    </StackPanel>
</Window>

主窗体XAML文件的后台：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            InitialCarList();
        }

        private void InitialCarList()
        {
            List<Car> carList = new List<Car>() 
            {
                new Car(){Automaker="VolksWagen",Name="Beetle",Year="1990",TopSpeed="320"},
                new Car(){Automaker="VolksWagen",Name="Golf GTI",Year="1988",TopSpeed="220"},
                new Car(){Automaker="VolksWagen",Name="Jetta",Year="2002",TopSpeed="220"},
                new Car(){Automaker="VolksWagen",Name="Pheaton",Year="2005",TopSpeed="180"}
            };
            listBoxCars.ItemsSource = carList;
        }
    }
}

实体Car类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            InitialCarList();
        }

        private void InitialCarList()
        {
            List<Car> carList = new List<Car>() 
            {
                new Car(){Automaker="VolksWagen",Name="Beetle",Year="1990",TopSpeed="320"},
                new Car(){Automaker="VolksWagen",Name="Golf GTI",Year="1988",TopSpeed="220"},
                new Car(){Automaker="VolksWagen",Name="Jetta",Year="2002",TopSpeed="220"},
                new Car(){Automaker="VolksWagen",Name="Pheaton",Year="2005",TopSpeed="180"}
            };
            listBoxCars.ItemsSource = carList;
        }
    }
}

下面是两个Converter：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Data;
using System.Windows.Media.Imaging;

namespace WpfApplication1
{
    class AutomakerToLogoPathConverter:IValueConverter
    {
        #region IValueConverter 成员

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            string uriStr = string.Format(@"/Resources/Logos/{0}.jpg",(string)value);
            return new BitmapImage(new Uri(uriStr, UriKind.Relative));
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }

        #endregion
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Data;
using System.Windows.Media.Imaging;

namespace WpfApplication1
{
    class NameToPhotoPathConverter:IValueConverter
    {
        #region IValueConverter 成员

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            string uriStr = string.Format(@"/Resources/Images/{0}.jpg",(string)value);
            return new BitmapImage(new Uri(uriStr, UriKind.Relative));
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }

        #endregion
    }
}
