绑定图标取决于枚举在WPF树视图

我在树状文本框，我想将我的枚举：绑定图标取决于枚举在WPF树视图

<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=AcceptationStatusGlobalFlag}" /> 

public enum AcceptationStatusGlobalFlag 
    { 
     NotReady = 0, 
     Ready = 1, 
     AcceptedByAdmin=2 
    }

到图标。将有3个图标，让说ready.jpg，notready.jpg和AcceptedByAdmin.jpg

国家及地区设有台球AcceptationStatusGlobalFlag和两个我想要显示此枚举/图标

  <TreeView Name="structureTree" SelectedItemChanged="structureTree_SelectedItemChanged" Grid.Row="0" Grid.Column="0" ItemsSource="{Binding}" Height="413" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Visible" Width="Auto" PreviewMouseRightButtonUp="structureTree_PreviewMouseRightButtonUp" FontFamily="Verdana" FontSize="12"> 
       <TreeView.Resources> 
        <HierarchicalDataTemplate DataType="{x:Type ServiceMy:Country}" 
           ItemsSource="{Binding Path=ListOfRegions}"> 
         <StackPanel Orientation="Horizontal"> 
          <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=Name}"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text=" H:"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=NumberOfHotels}"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text=" "/> 
          <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text=" FG:"/> 
          <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=AcceptationStatusGlobalFlag}" /> 
       <!--<Button Name="BTNAddRegion" Height="20" Content="+" Click="BTNAddRegion_Click"></Button>--> 
      </StackPanel> 
        </HierarchicalDataTemplate> 
        <HierarchicalDataTemplate DataType="{x:Type ServiceMy:Region}" 
           ItemsSource="{Binding Path=ListOfProvinces}"> 
         <StackPanel Orientation="Horizontal"> 
          <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=Name}"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text=" H:"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=NumberOfHotels}"/> 
       <TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text=" "/> 
       <!--<Button Name="BTNAddProvince" Height="20" Content="+" Click="BTNAddProvince_Click"></Button>--> 
      </StackPanel> 


        </DataTemplate> 

       </TreeView.Resources> 
      </TreeView> 
     </GroupBox> 

    </StackPanel>

对于无转换器的解决方案，请参阅：ht tp：//stackoverflow.com/questions/2787725/how-to-display-different-enum-icons-using-xaml-only/41150128#41150128 – 2016-12-14 19:00:28

创建Value Converter

它需要你的枚举值，并返回相应的图标的文件名。

[ValueConversion(typeof(AcceptationStatusGlobalFlag), typeof(string))] 
public class AcceptationStatusGlobalFlagToIconFilenameConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     switch ((AcceptationStatusGlobalFlag)value) 
     { 
      case AcceptationStatusGlobalFlag.Ready: 
       return "ready.jpg"; 
      case AcceptationStatusGlobalFlag.NotReady: 
       return "notready.jpg"; 
      case AcceptationStatusGlobalFlag.AcceptedByAdmin: 
       return "AcceptedByAdmin.jpg"; 
      default: 
       return null; 
     } 

     // or 
     return Enum.GetName(typeof(AcceptationStatusGlobalFlag), value) + ".jpg"; 
    } 

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

您需要在您的XAML

<Window ... xmlns:converters="clr-namespace:App.Converters" ...> 
    <Window.Resources> 
     <converters:AcceptationStatusGlobalFlagToIconFilenameConverter x:Key="IconConverter"/> 
    </Window.Resources>

添加到该ADC的参考用图像替换您的TextBlock

<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=AcceptationStatusGlobalFlag}" />

，并告诉它使用转换器

<Image Source="{Binding AcceptationStatusGlobalFlag, Converter={StaticResource IconConverter}}"/>

如果图形是在XAML资源中定义的可缩放形状，应该怎么做，而不是文件中的位图？ – Anthony 2011-01-17 15:53:28

@Anthony你应该创建一个新的问题。 – mak 2011-01-20 23:31:54

最简单的解决方法是使用值转换器;因此请创建一个IValueConverter实现，将您的枚举转换为相应的图像。

你应该使用绑定与价值转换器：http://blogs.msdn.com/bencon/archive/2006/05/10/594886.aspx
