>>>I've wrote a combo sub-class that allows the user to select the type of graph he wants. The combo has 2 columns: One with the description of the type, another one with the constant value of the charttype property. Value is bounded to column 2. When the user selects an option, i assign the charttype as the value of the combo.
>>>All works fine, even if the value is a negative one, but i'm not able to initialize the value of the combo to a negative value. I've tried in the init event of the control, in the init of the form and in design mode, but combo does not show the apropiated value. Any idea?

Sorry, it's bad sample. If you want to have two column and let say negative value in second column, then code should look like:
*** combo init event
this.addlistitem("a", 1, 1)
this.addlistitem("-1", 1, 2)
this.addlistitem("b", 2, 1)
this.addlistitem("2", 2, 2)
this.addlistitem("c", 3, 1)
this.addlistitem("-3", 3, 2)

Now to 'initiate' the combo you can issue Combo.Value="-3" to get 'c' in text portion of the combo.
