In CmoboBoxW , How Can I draw items manually ? and What is the difference between Fixed and Variable drawing Enums in DrawMode property .

I am asking this question because I - in most cases - use the combo style "List" , which draws a gray background for the combo box , once I changed the DrawMode property , the backcolor I set is what is shown .
My last concern is , If I draw items manually , would this affect some features or other properties ?

Thanks in advance .

Edit 1 :
Another question . what is the property ExtendedUI is intended to do . The only effect I noticed is that : If it is set to true , scrolling the combobox opens the list otherwise , scrolling does not open the list and changes the list index and text of the combobox while the list is not opened or dropped down .

Edit 2 :
I have tested the ItemDraw Event and noticed that it is not fired when the DrawMode property is set to Normal . Thus I thought it would be something to start with . But , I did not get the point of some parameters like ItemAction and ItemState . Or This is not right start point ?
