Dealing with Selectionchanged and currentlyselected item in viewmodel?

Question

Could anyone please provide an example of how i can handle storing the currently selected item, within a longlistselector( or any list control ) within my viewmodel. I seem to fail to understand how to implement the logic within the viewmodel, keeping it out of the event handler within the pages codebehind! thanks

See this article, if you want to call events with binding http://www.wiredprairie.us/blog/index.php/archives/1701

If you want to store the SelectedItem in your ViewModel, your xaml should look something like this:

<ComboBox SelectedItem="{Binding MySelectedItem, Mode=TwoWay}"/>

and your ViewModel should look like this:

public class ContactModel : ViewModelBase

public ContactModel()
{
    MySelectedItem = "";
}

   private string _myselecteditem
   public string MySelectedItem
    {
        get { return _myselecteditem; }
        set
        {
            _myselecteditem = value;
            RaisePropertyChanged(() => MySelectedItem);
        }
    }
}
