SelectedItem Icon differs with declaration.

[AKE]

I use such code for add items to CTreeView
tvInsert.item.mask = TVIF_TEXT|TVIF_IMAGE|TVIF_SELECTEDIMAGE;
tvInsert.item.iImage = 1;
tvInsert.item.iSelectedImage = 1;
But when I run program in selection field I see other icon - #0, which differs with common state image...
What wrong in my actions?
