How to select an item in built-in EpiCombo using code

I need to populate Sales Category on Order Line Detail tab automatically. If I write OrderDtl.SalesCatID field directly via data view, the Combo does not display correctly. Basically, I want to use code to select a Sales Category automatically. Has anyone done this before? Thanks

Usually you will also need to set the description also.

Thank you, Greg. That did it.

Good, mark the question as solved.
