I am creating a browser based InfoPath 2010 form. I have a dropdown list control (Metro) and Multiple Selection list box (Store). Both these controls are bound to SharePoint 2010 list.
Now I can definitely filter "Store" based upon selection in "Metro" but the real issue is I would also like to show all the values in the "Store" based upon a value called - Show all in "Metro" selection. I did that before but don't seem to recall this now
