Formatting date/Number DataGridColumn

[FrancescoCosta78]

Buonasera, il parametro stringformat non funziona con una risorsa static ?
example:

This work:
<dg:DataGridColumn Title="Data" PropertyName="Data"
Width="85" StringFormat="{}{0:dd/MM/yyyy} " />

This not work:
xmlns:tool="clr-namespace:MyApp.Tool"
...
<dg:DataGridColumn Title="Data" PropertyName="Data"
Width="85" StringFormat="{}{0: {x:Static tool:RS_Globali.rs_gFormatoData} } " />

Has anyone had the same problem?
