I'm trying to create custom form for a SharePoint 2007 document library using SharePoint Designer 2007. Is it possible to make a form field conditionally required based on the selected item from a drop-down in the the same parent form?
I was able to implement something similar pretty quickly using InfoPath 2007, but my project requirements call for this to be implemented using SharePoint Designer 2007. I have access to Visual Studio 2010 as well, if not possible in SharePoint Designer 2007, can something like this can be implemented using VS2010? Input is appreciated.
