Two commands to one button

Question

I'd like to bind two actions to a ModernUI link: when clicked, it should a) trigger a RelayCommand and b) navigate. I have googled and read but could not find a solution. So far, I only made it to either bind or navigate, but not both..

E.g. in the sample ModernUI application, Navigation takes place like this:

                <Button Content="introduction" Margin="0,0,4,0"
                        Command="mui:LinkCommands.NavigateLink"
                        CommandParameter="/Pages/Introduction.xaml"/>

But then the Command property is already used, so how could I attach my second Command to it?

                <Button Content="introduction"
                        Command="{Binding MyCommand}">

I've also tried using a ListBox, where I can use the SelectedItem property, but this one has no Command property.

I'd be thankful for a hint!

why not call the LinkCommand within your MyCommand in your viewmodel? — blindmeis, Mar 23 '15 at 09:50
I've tried that, too, but got stuck when the navigation tab bar did not reflect the current page and also thought that this would be a violation of MVVM ? — peter, Mar 23 '15 at 10:03

This CodeProject site shows an implementation of a list of Commands that presents itself to be one command. That way, calling one would call the others.

In fact, the class just implements ICommand and an ObservableCollection of Commands that get executed when called.

That seems a proper solution for your problem.
