I need to create a ContextMenu where I want to pass a currently selected index of the datagrid to a ViewModel using CommandParameter. The following Xaml code doesn't work. What might be the problem?

<dg:DataGrid ItemsSource="{Binding MarketsRows}"
    <dg:DataGrid.ContextMenu >
        <ContextMenu >
            <MenuItem Header="Add Divider"
                  CommandParameter="{Binding Path=SelectedIndex,
RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type dg:DataGrid}}}"
                  Command="{Binding Path= AddDividerCommand}"/>
        </ContextMenu>
    </dg:DataGrid.ContextMenu>
</dg:DataGrid>

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
