Question

I have a problem, I need to get the selected Item from a ContextMenu in a LongListSelector.
Before I was using a normal ListBox and I did it with:

var selectedItem = myList.ItemContainerGenerator.ContainerFromItem(menuItem.DataContext) as ListBoxItem;

But now I’m using the LongListSelector and this method doesn’t work.

Who can I do it?

Answer 1

If the LongListSelector is databound, you can use the DataContext property to access the selected item.

private void MenuItem_Click( object sender, RoutedEventArgs e ) {
    MyObject obj = ( sender as MenuItem ).DataContext as MyObject;
}

assuming your LongListSelector is databound to a list of MyObject objects.
