    Hello,

    I have a Carousel populated with Observsable collection using MVVM. I want to be able to filter the carousel with a button click event.

    Any Samples would be great

    THANKS
        Rick

    Hello,

    Have you tried Where() extension method?

    ICollectionView EmployeeList = CollectionViewSource.GetDefaultView(Radc.ItemsSource);
      
    EmployeeList.Filter = new Predicate<object> (Contains);
          
            }
            private bool Contains(object o)
            {
                EmployeeList oEmployee = o as This.RadRadioButton.Tag(Value);
                if (oEmployee == null) return true;
      
                return !(Value);

    this is what i have so far,

    Regards,
    Rick

    Hi,

     If you call Refresh for your ICollectionView in this case you will reevaluate the filter. 

    Kind regards,

    Hi,

     You just need to call Refresh method of EmployeeList in your button click event handler.
