I have a ObservableCollection, I can add and remove item from the collection. But I can't replace an existing item in the collection. There is a way to replace an item and reflect that on my bound components.
System.Collections.Specialized.NotifyCollectionChangedAction.Replace
Can anyone please show me how to accomplish this?
Simple extension method for replace item in observable collection:
public static void ReplaceItem<T>(this ObservableCollection<T> items, Func<T, bool> predicate, T newItem)
{
for (int i = 0; i < items.Count; i++)
{
if (predicate(items[i]))
{
items[i] = newItem;
break;
}
}
}
