Question

For my WPF application I’m using MVVM, and now I want to show a generated context menu when the user right-clicks on something.
Routing the right-click to some action was easy, but how do I show a contextmenu which items are generated by the ViewModel?

I don’t even have an idea where to start to display a context menu, since I do not have direct access to the view in MVVM.

Apologies for the delay in replying, had to have a bit of an experiment to get it to work. Give the following code a go. I just set up my own rubbish data source just so I could display some sort of data. It only displays if I right click over the first column heading and no where else… which I think is what you want, right? Let me know how you get on…any probs will continue to have a think.

   <Grid>
    <ListView Margin="8,8,33,12"  ItemsSource="{Binding Source={StaticResource Stuff}, Path=MyCollection}">
        <ListView.View>
        <GridView>
                <GridViewColumn Width="100" DisplayMemberBinding="{Binding}">
                    <GridViewColumnHeader>ProductName
                        <GridViewColumnHeader.ContextMenu>
                            <ContextMenu Name="MyMenu">
                                <MenuItem Header="Sort by..."/>
                                <MenuItem Header="Follow link..."/>
                            </ContextMenu>
                        </GridViewColumnHeader.ContextMenu>
                    </GridViewColumnHeader>
                </GridViewColumn>
                <GridViewColumn Width="100" Header="Product Name" DisplayMemberBinding="{Binding Path=Length}"/>
        </GridView>
        </ListView.View>
    </ListView>
</Grid>
