I have searched high and low for a potential solution to this, but I am not sure how to do it, so if anyone smarter than me could assist, I'd appreciate it.

 

basically I have a control with two fields. One field is a textarea field that accepts multiple values and the second is a combobox. I want to have the selected choices in the textarea field to populate the combobox when values are entered into it. I realize that I likely have to write some sort of update code when the onchange event occurs, but I am not sure how to get just that combobox to refresh its choices since none of the fields seem to have a partial refresh option on them. 

 

I have code to generate the list dynamically in the combobox, but obviously it won't run without reacting to some event. 

 

Can someone point me in the right direction? Thanks.
