从XAML访问枚举以访问字典对象 [英] Accessing a enum from XAML to access a Dictionary-object

问题描述

因此问题如下:

我有一个Dictionary< FormatEnum，string>我想从XAML访问此词典.
FormatEnum具有类型Small，Medium和Big，并且字符串包含图片的URL.

我尝试了以下代码:

So the problem is the following:

I have a Dictionary<FormatEnum,string> and I want to access this Dicitionary from XAML.
FormatEnum has the types Small, Medium and Big, and the string contains a URL to a picture.

I tried the following code:

<ItemsControl Name="MixControl">
 <ItemsControl.ItemTemplate>
  <DataTemplate>
   <Border CornerRadius="5" BorderThickness="2" BorderBrush="Black" Width="56" Height="56">
    <Border.Background>
     <ImageBrush ImageSource="{Binding CoverUrls[{x:Static tracks:CoverFormat.Small}]}"/>
    </Border.Background>
   </Border>
  </DataTemplate>
 </ItemsControl.ItemTemplate>
</ItemsControl>

track是名称空间引用，我在某处阅读过使用x:Static ...但它无法正常工作...
感谢您的帮助！

tracks is the namespacereference, and I read somewhere to use x:Static... But it won''t work ...
Thanks for your help!

推荐答案

您可以使用转换器将枚举更改为所需的枚举.我在WP7应用程序中使用它来将状态枚举转换为图像，例如绿色代表良好，红色代表存在错误.

You can use a converter to change the enum into whatever you need. I use this in a WP7 app to convert a status enum to an image like a green one for good or a red one for an error.
