一起学Windows Phone7开发(十三.八 ListBox控件)

      在Phone7中去掉了listview控件，就只有这个listbox控件，不过这个控件功能非常强大，完全可以实现listview的功能。 因为这个控件也相当于一个容器，可以通过ListItem来组合多个控件而得到不同功能的list。

Xaml:

<ListBox Grid.Row="1" Height="567" HorizontalAlignment="Left" Margin="12,53,0,0" Name="listBox1" VerticalAlignment="Top" Width="460">

            <ListBox.ItemTemplate>

                <DataTemplate>

                    <StackPanel Orientation="Horizontal">

                        <Image Source="{Binding ImgSource}" Width="130" Height="130"/>

                        <TextBlock Text="{Binding Name}" Foreground="Yellow" FontSize="25"/>

                    </StackPanel>

                </DataTemplate>

            </ListBox.ItemTemplate>

        </ListBox>

//{Binding ImgSource}：动态绑定图片资源。

//{Binding Name}：动态绑定text文字。

源代码：

ImageList item1 = new ImageList();

    item1.ImgSource = new BitmapImage(new Uri("Images/Chrysanthemum.jpg", UriKind.Relative));

    item1.Name = "Chrysanthemum.jpg";

    list.Add(item1);

 

     ImageList item2 = new ImageList();

     item2.ImgSource = new BitmapImage(new Uri("Images/Desert.jpg", UriKind.Relative));

     item2.Name = "Desert.jpg";

     list.Add(item2);

 

    ImageList item3 = new ImageList();

    item3.ImgSource = new BitmapImage(new Uri("Images/Hydrangeas.jpg", UriKind.Relative));

    item3.Name = "Hydrangeas.jpg";

    list.Add(item3);

 

    listBox1.ItemsSource = list;

<ListBox Height="605" HorizontalAlignment="Left" Margin="10,6,0,0" Name="listBox1" VerticalAlignment="Top" Width="460" >

      <ListBox.ItemTemplate>

           <DataTemplate>

              <StackPanel Orientation="Horizontal">

                 <Button  Content="{Binding ColorName}" Click="Button_Click"/>

                 <TextBlock  x:Name="tb" Text="{Binding ColorName}" FontSize="35"/>

               </StackPanel>

           </DataTemplate>

       </ListBox.ItemTemplate>

 </ListBox>

void MainPage_Loaded(object sender, RoutedEventArgs e)

        {

            ColorItem color = new ColorItem();

            color.ColorName = "Red";

            color.ColorValue = Colors.Red;

            list.Add(color);

 

            ColorItem color1 = new ColorItem();

            color1.ColorName = "Green";

            color1.ColorValue = Colors.Green;

            list.Add(color1);

 

            ColorItem color2 = new ColorItem();

            color2.ColorName = "Blue";

            color2.ColorValue = Colors.Blue;

            list.Add(color2);

 

            this.listBox1.ItemsSource = list;

        }

 

        private void Button_Click(object sender, RoutedEventArgs e)

        {

            string button = (sender as Button).Content as string;

          

             int index = 0;

             string color = string.Empty;

             for(index=0; index<list.Count; index++)

             {

                if(button == list[index].ColorName)

                {

                    color = list[index].ColorName;

                    break;

                }

 

             }

            

             ListBoxItem lbi = this.listBox1.ItemContainerGenerator.ContainerFromIndex(index) as ListBoxItem;

             TextBlock tb = FindFirstVisualChild<TextBlock>(lbi, "tb");

             tb.Foreground = new SolidColorBrush(list[index].ColorValue);

             

            }
