I have a drop down list in the infopath form and based on the selection(Only if aprticular value is selected ) in dropdown listbox need to make some of the controls as mandatory in the infopath form. This has to be done using rules. I am not planning to use any custom code in my form. How this can be achieved? Please Help !!
