Hello
Where are the methods I can call on a combo objects acquired with getCustomCombo?

Here you can find a tutorial:

Thank you.
Is there a way for force the sort of a combo programatically?

Hello
Also, if possible. How does pick, scroll, place a combo item as selected. I know how to do it in javascript, just not clear how to do it in the grid.

Unfortunately such feature is not available. You set the order while loading the options of the select (the first loaded option will be on the first position in the list)

programmatic scrolling of the combo list is not supported.
For placing the combo item as selected you may just set the required value to a cell:
mygrid.cellById(row_id,col_ind).setValue(option value);
