Net tutorial Hello Satal, Thank you for your response. the problem is when user clicks on the remove item [button] it opens up an inputbox, the user has to type the item manually in inputbox, so there is no selectedindex from the listbox.

So what happens when I add/remove something from that data source, how do I get notified??? It inherits from a Collection View, which implements the INotify Collection Changed interface, which has the Collection Changed event. This is sample code that demonstrates how to use this.

I did some digging around, but realised there’s no such event that gets triggered. So you will now be notified of changes in your control’s Items due to changes in your data source.

Whether a XAML pattern is positive or a very problematic anti-pattern is often hard to discern.

It takes careful analysis to understand when a certain pattern is positive, and when it might turn into an anti-pattern.

The trick is to look at the the Items property, which is of type System. You might also want to learn more about the Notify Collection Changed Event Args, it has some useful properties in there.
