How do I pass the information from View to ViewModel with DelegateCommand?

Question

In my View, I have a button.

When the user clicks this button, I want to have the ViewModel save the context of the TextBlock in the database.

In your VM:

private DelegateCommand _saveCmd = new DelegateCommand(Save);

public ICommand SaveCmd{ get{ return _saveCmd } }

public void Save(string s) {...}

In you View, use CommandParameter like Matt's example.
