Interesting, so I play. A test form is open in form view and in immediate window
?forms!form1.command2.quickstyle and the result is
0
which means no quick style, yes?
forms!form1.command2.quickstyle = 3 and it turns white (background color) with an orange border
Perhaps your issue is something else, such as the tag or the wrong event. According to the documentation the property is just there - you don't have to create it.
Why do this in the load event? You can't save design changes that are done in form view even if you get that code to work.
The more we hear silence, the more we begin to think about our value in this universe.
