WPF XAML bind resource key to property - wpf

Question

I have a set of icons stored in a file named Icons.xaml in MyProject/Resource.
<!-- Icons.xaml -->
<DrawingImage x:Key="CounterClockWiseDirection">...</DrawingImage>
<DrawingImage x:Key="ClockWiseDirection">...</DrawingImage>
In my ViewModel there's a property named ClockWiseDirection which should control this image.
<!-- MyControUC.xaml -->
<ListBox ItemsSource="{Binding ItemList}" SelectedItem="{Binding SelectedItemFromList}">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="70*" />
<ColumnDefinition Width="10*" />
<ColumnDefinition Width="10*" />
<ColumnDefinition Width="10*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<Image Grid.Column="1" />
<Image Grid.Column="2" Source="{StaticResource CurrentItem.ClockWiseDirection}" />
<Image Grid.Column="3" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
This obviously doesn't work, I'm quite new to WPF so I'm bit confused about the solution to use/look.

Answer 1

It seems like you are trying to return a resource key from the view model. You might as well return the actual DrawingImage instead and bind to it in your XAML markup:
Source="{Binding ClockWiseDirection}"
If the resource that is defined in your Icons.xaml ResourceDictionary is in scope, you could get a reference to it by calling FindResource and cast the result:
ClockWiseDirection = `FindResource("CounterClockWiseDirection") as DrawingImage;`
The other option is to create a ResourceDictionary object dynamically and get the resource from there:
ResourceDictionary rd = new ResourceDictionary() { Source = new Uri("Themes/generic.xaml", UriKind.RelativeOrAbsolute) };
ClockWiseDirection = rd["CounterClockWiseDirection"] as DrawingImage;
