Question

I have an List values with a ResourceKey and a Caption, these values are both strings. The Resource is the name of an actual resource defined in a resource dictionary. Each of these ResourceKey Icons are Canvas’s.

<Data ResourceKey='IconCalendar' Caption='Calendar'/> <Data ResourceKey='IconEmail' Caption='Email'/> 

I then have a list view which has a datatemplate with a button and a text caption below the button. What I want to do is display Resource static resource as the content for the button.

<ListView.ItemTemplate>     <DataTemplate>         <Grid>             <Grid.RowDefinitions>                 <RowDefinition Height='*' />                 <RowDefinition Height='Auto' />             </Grid.RowDefinitions>              <Button Content='{Binding ResourceKey}' Template='{StaticResource  RoundButtonControlTemplate}'/>             <TextBlock Grid.Row='1' Margin='0,10,0,0' Text='{Binding Caption}' HorizontalAlignment='Center' FontSize='20' FontWeight='Bold' />         </Grid>     </DataTemplate> </ListView.ItemTemplate> 

I think I have tried every permutation with binding staticresource etc.

I am open to alternatives, I know it may be easier to just have an image and set the source property.

Thanks

After having a little think I ending up using a ValueConvertor like so:

class StaticResourceConverter : IValueConverter {     public object Convert(object value, Type targetType, object parameter, CultureInfo culture)     {         var resourceKey = (string)value;          return Application.Current.Resources[resourceKey];     }      public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)     {         throw new Exception('The method or operation is not implemented.');     } } 

and the binding on the button becomes

<Button Content='{Binding ResourceKey, Converter={StaticResource resourceConverter}}' />
