Toolkit(http://silverlight.codeplex.com/)中有一个不错的控件：HubTile。
但这个控件只能用于173*173的Tile，如果想放其他尺寸的的就麻烦一些了（一行并排3个显示的Tile）

下面是实现可重定义tile大小的完整代码

步骤1：写一个Converner类，用于缩放double类型的数值

需要命名空间：

using System.Globalization;
using System.Windows.Data;

  1. <span style="font-size:18px;">    public class DoubleScaleConverner : IValueConverter
  2. {
  3. public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
  4. {
  5. if (value is double && targetType == typeof(double))
  6. {
  7. double dbOrig = (double)value;
  8. if (parameter is string)
  9. {
  10. double dbParam;
  11. if (double.TryParse((parameter as string), out dbParam))
  12. {
  13. return Math.Round(dbOrig * dbParam);
  14. }
  15. }
  16. }
  17. return value;
  18. }
  19. public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
  20. {
  21. return null;
  22. }
  23. }</span>

2. ResourceDictionary文件中，将converner声明出来
  1. <span style="font-size:18px;">xmlns:my="clr-namespace:HubTileTest"
  2. an>
  1. <span style="font-size:18px;">    <my:DoubleScaleConverner x:Key="doubleScaleConverner" /></span>

3. 用blend生成hubtile的style，并做修改成这样
  1. <span style="font-size:18px;"><Style x:Key="customHubTileStyle" TargetType="toolkit:HubTile">
  2. <Style.Setters>
  3. <Setter Property="Height" Value="173"/>
  4. <Setter Property="Width" Value="173"/>
  5. <Setter Property="Background" Value="{StaticResource PhoneAccentBrush}"/>
  6. <Setter Property="Foreground" Value="#FFFFFFFF"/>
  7. <Setter Property="Template">
  8. <Setter.Value>
  9. <ControlTemplate TargetType="toolkit:HubTile">
  10. <StackPanel x:Name="Viewport"
  11. Height="{TemplateBinding Height}" Width="{TemplateBinding Width}">
  12. <StackPanel.Resources>
  13. <CubicEase EasingMode="EaseOut" x:Key="HubTileEaseOut"/>
  14. </StackPanel.Resources>

4. 如果要使用一个136*136的tile，这样写个样式就行了
  1. <span style="font-size:18px;">    <Style x:Key="smallTileStyle" TargetType="toolkit:HubTile" BasedOn="{StaticResource customHubTileStyle}">
  2. <Setter Property="Height" Value="136" />
  3. <Setter Property="Width" Value="136" />
  4. <Setter Property="Background" Value="Purple" />
  5. </Style></span>
