wpf listbox selected item change event





I am using PRISM and MVVM. What I want is when I click on button, the same item is selected from RadListBox automatically,(This part working fine).Even more strange thing: I tried the same thing with standard WPF ListBox by adding attached behavior for selection changed event and attached A common problem that people face using the Model-View-ViewModel (MVVM) pattern is handling multiple selected items in a ListBox with extended selection mode turned on.public event PropertyChangedEventHandler PropertyChanged WPF Event ListBox SelectionChanged I have a problem with listbox.Is there any way to change it? The SelectionChangedEventArgs will contain which item was deselected and which item was selected.
