访问staticResource中的属性

Question

I am trying to use a property of a resource defined in xaml like this:

<Window.Resources>
    <map:TileLayer x:Key="OpenStreetMap" SourceName="OpenStreetMap"
                   Description="Maps © [OpenStreetMap Contributors](http://www.openstreetmap.org/copyright)"
                   TileSource="http://{c}.tile.openstreetmap.org/{z}/{x}/{y}.png"
                   MaxZoomLevel="14"/>

and then use the Description property to set Text of a TextBlock. I have tried this but it does not work.

<TextBlock Text="{Binding Source={StaticResource OpenStreetMap.Description}}"/>
<TextBlock Text="{StaticResource OpenStreetMap.Description}"/>

How can I access the property in a resource defined in xaml?

Answer 1

This way:

<TextBlock Text="{Binding Source={StaticResource OpenStreetMap}, Path=Description}"/>

Or shorter:

<TextBlock Text="{Binding Description, Source={StaticResource OpenStreetMap}}"/>

Note that the Description property contains markdown text. You could use the HyperlinkText helper class like this:

<TextBlock map:HyperlinkText.InlinesSource="{Binding Description,
                                             Source={StaticResource OpenStreetMap}}"/>
