I'm using Infopath 2010 and created form with Multiple Selections in List Box. I want to restrict users to single selection only. How do i acheive this without any coding. I'm from non-technical person. Just working on some process efficiency using Infopath.
Should the item only ever have one selection? You could simply change the field to not allow multiple values from within SharePoint. Easiest way to make sure the form updates properly after the change is to adjust the field in the library on SharePoint, then select the 'Customize Form' button to start editting the infopath form -- it should prompt you that the field definitions have changed and you need to update them.
