Hello group...

I've created a collection class that implements the following interfaces: IBindingList, IList, ICollection, IEnumerable and ITypedList:

abstract class DataCollectionBase : IBindingList, IList, ICollection, IEnumerable, ITypedList
{
   private ArrayList innerList = null;
   private System.Type itemType = null;

   public DataCollectionBase()
   {
       this.innerList = new ArrayList();
   }

   protected System.Type ItemType
   {
       get { return this.itemType; }
       set { this.itemType = value; }
   }

   // List Changed Notification
   protected virtual void OnInsertComplete(int index, object newValue)
   {
       if (ListChanged != null)
       {
           ListChangedEventArgs args = new ListChangedEventArgs(ListChangedType.ItemAdded, index, -1);
           ListChanged(this, args);        // The StackOverflowException is thrown here
       }
   }

   // IList Implementation
   int IList.Add(object value)
   {
       int index = this.innerList.Add(value);
       OnInsertComplete(index, value);
   }

   // IBindingList Implementation
   public event ListChangedEventHandler ListChanged = null;

   object IBindingList.AddNew()
   {
       object newItem = null;

       // Here I create the new item with Reflection, based on the ItemType property and store a reference in 'newItem''.

       ((IList)this).Add(newItem);
       return newItem;
   }
}

I'm using my collection as a value for the DataSource property in a DataGrid control.
The IBindingList.AddNew() method works fine and the new item is instantiated via Reflection, but when I invoke the ListChanged event handler within the OnInsertComplete(..) method, the StackOverflowException is thrown.
I don't understand what's happening to my collection, the DataGrid control is the only component that's consuming the ListChanged event.

I really need your help...

Thank you all
