Removing Items from Gridview and refreshing the gridview without redirecting to the same Page.(Windows Phone 8.1 Xaml)

Question

I have a gridview with a Usercontrol as its itemtemplate.

In the Usercontrol I have a flyout attached to it using which the user can choose to delete the entry. After deletion how do I remove the entry/Update the gridview without redirecting to the samePage and removing the backstack entry?

Please note that I am deleting/modifying the itemssource in the usercontrol's codebehind buttonclick event.

Answer 1

If your itemssource implements INotifyCollectionChanged, it will automatically reflrect Addition ans Removals in the GridView.

You can use ObservableCollection as ItemsSource, it already implements it.

And of course you can just remove the items directly using GridView.Items.Remove (or RemoveAt).
