Version 0.8 (1.03.97)
1) The context help is available.
2) Added the property OnAddNewItem : TAddNewDBTreeNodeEvent 
TAddNewDBTreeNodeEvent = procedure(Sender: TObject; var DBTreeNode: TDBTreeNode) of Object;
This event is called when a new item is adding.
For example:
procedure TForm1.DBTreeView1AddNewItem(Sender: TObject;

  if(DBTreeNode.KeyFieldValue = 15) then
    DBTreeNode.TreeNode.ImageIndex := 2;
end;

II. Bugs
Version 0.8 (1.03.97)
1) TDBTreeView. The DisableControls and EnableControls methods work perfectly now. We nave been noticed that the code:
  Table.DisableControls;
  Table.Next;
  Table.EnableControls;
or 
Table.Locate('ID', IDValue, []);
didn't work. Now it's worked all right. 
Thank you Bas Wiebinga (Terbit Information, The Netherlands) for noticing us about this bug.

2) The bug with popup form TDBLookupTreeView is killed. TDBLookupTreeView on opening popup form  goes to the current DBTreeNode now.

3) DBTreeView. The bug on destroying DBTreeView is killed. The protection fault error on destroying DBTreeView was appear. 
thnak you Jessica Theodor (Museum Scientist, Museum of Paleontology,University of California, Berkeley) for noticing us this bug and for uploading to us DB.
