Hi, Dan - 

From what you've described, it sounds like what you are experiencing is that the Edit Control (the dynamically placed mechanism that handles all user input in a DW) is not immediately reflecting the property change in the underlying column DWObject. The edit control was probably not designed to change its appearance while focus stays on a column, but only when a column DWO receives focus.

If this is indeed the case, I think your options are limited. You might be have to perform a little sleight-of-hand to trick the Edit Control. If it were me, I would try to (a) SetRedraw(false), (b) SetColumn to another column, (c) Change the Italic property in the original column, (d) SetColumn back to the original column, and (e) SetRedraw(True). I've no idea if this will work, but this is what I would try.

I hope it works for you.

Regards, John
