>I'm using whatever record a user selects in a combo box to control the filter on a grid on the same form but it seems like my grid only refreshes after I click out of the combo box. What method do I put my Set Filter To command in so I can click the dropdown list on the combo box and right when I select one of the dropdown items it selects it and refreshes my adjacent grid?

Put your code in combo InteractiveChange. Can you use another alternatives to SET FILTER? SET FILTER and grid are not fond of each other...
