Change context menu in xaml - wpf

Question

I've got a view with two large context menus defined as resouces. They look something like this (only larger) :
<ContextMenu x:Key="ContextMenu1">
<MenuItem Header="Append" Command="{Binding AppendCommand}" />
<MenuItem Header="Edit" Command="{Binding AppendCommand}" />
</ContextMenu>
<ContextMenu x:Key="ContextMenu2">
<MenuItem Header="Delete" Command="{Binding DeleteCommand}" />
<MenuItem Header="Verify" Command="{Binding VerifyCommand}" />
</ContextMenu>
I know that I can dynamically show / hide items with the canExecute method of the command. But since this is two completely different modes I would like to just Bind to a bool property that decides which context menu to display. Something like this:
<ListView ContextMenu={binding ContextMenuSelector}>
Does anyone know how I can do something like that ?

Answer 1

Consider using a DataTemplateSelector.
The DataTemplateSelector enables you to display specific presentations based on the context of each datacontext item within your itemscontrol.
I have used it for context menu items that may differin behavior.

Answer 2

I got a few good ideas from the DataTemplateSelector, but I ended up with a style with data trigger:
<Style TargetType="{x:Type StackPanel}" x:Key="stackPanelStyle">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=AppendMode}" Value="True">
<Setter Property="ContextMenu" Value="{DynamicResource PanelContextMenuAttachFile}"></Setter>
</DataTrigger>
<DataTrigger Binding="{Binding Path=AppendMode}" Value="False">
<Setter Property="ContextMenu" Value="{DynamicResource PanelContextMenu}"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
