I have a list like this:
List<Controls> list = new List<Controls>
How to handle adding new position to this list?
When I do:
myObject.myList.Add(new Control());
I would like to do something like this in my object:
myList.AddingEvent += HandleAddingEvent
And then in my HandleAddingEvent
delegate handling adding position to this list. How should I handle adding new position event? How can I make this event available?
I believe What you're looking for is already part of the API in the ObservableCollection(T) class. Example:
ObservableCollection<int> myList = new ObservableCollection<int>();
myList.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(
delegate(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
{
MessageBox.Show("Added value");
}
}
);
myList.Add(1);
