Wie setze ich ContextMenu eines gebundenen Objekts?

Question

Ich versuche folgendes zu erreichen:

<Style TargetType="ListBoxItem"> 
    <Setter Property="ContextMenu"> 
     <Setter.Value> 
      <ContextMenu> 
       <MenuItem Name="mnuEdit" Header="_Edit" Click="MenuItem_Click" /> 
      </ContextMenu> 
     </Setter.Value> 
    </Setter> 
<Style> 

Aber es wirft die folgende Ausnahme:

Cannot add content of type 'System.Windows.Controls.ContextMenu' 
to an object of type 'System.Object'. 
Error at object 'System.Windows.Controls.ContextMenu' 
in markup file blah blah blah 

Answer 1

dies stattdessen versuchen:

<ContextMenu x:Key="contextMenu"> 
    <MenuItem Name="mnuEdit" Header="_Edit" Click="MenuItem_Click" /> 
</ContextMenu> 

<Style TargetType="ListBoxItem"> 
    <Setter Property="ContextMenu" Value="{DynamicResource contextMenu}" /> 
</Style>
