>Is it possible to set a different tool tip text for each element of combobox according selected option by the user?

Each Item has its own Tooltip, or when the user selects an item then the Tooltip of the combo changes.
If you want the second:
In InterActiveChange Event of the combo put:
this.ToolTipText = [whatever you want]
