Hi,
I want to create a Resource Library of Drawing Brushes.
The Idea is create a base drawing brush  and change the color throw a dependency propertie and use the new drawing brush in xaml. (i don´t create a new drawing. the drawing is same but the colors changed)

I can do throw this:
DrawingBrush drwBrush = Mystyles[myDrawing] as DrawingBrush;
drwBrush.SetValue(MyProperties.InternalSolidBrushProperty, Mystyles[keySolidBrush]);

I try this way but dosen´t work :( 
                   x:Key="SymbolLock2"
                  Stretch="Uniform" 
                  custom:MyProperties.InternalSolidBrush="{StaticResource SolidBrushOver}"
                  Drawing="{Binding Source={StaticResource SymbolLock},Path=Drawing}"/>

Any Ideas?  Dependency propertie InternalSolidBrushProperty dosen´t change the color of base drawing.!!
 
The code:
 // DependencyProperty  
 public static readonly DependencyProperty   InternalSolidBrushProperty;


//DrawingBrush
 custom:MyProperties.InternalSolidBrush="{StaticResource
SolidBrushIconMenuSecondary}">
        
            
                
......
                               

                
            
        
   

Best Regards
