How to set ContextMenu of a bound item?

问题

I am trying to achieve the following:

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

But it throws the following exception:

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

回答1:

Try this instead:

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

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