I have a WPF UserControl that contains a ComboBox. I need to attach an event listener to the ComboBox.Items collection.
public MyUserControl()
{
InitializeComponent();
((INotifyCollectionChanged)comboBox.Items).CollectionChanged +=
ComboBoxItemsChanged;
}
But I cant seem to figure out how to detach it. Or is that handled automatically when the entire control is garbage collected?
Implement IDisposable interface and detach event handler in Dispose method
