In InfoPath, I'm pulling in a list from SharePoint to populate the selections. I'd like to add a "Select All" option to select/deselect all items. How do I do this within InfoPath 2010?
Good question! Don't believe there is any easy to do this without code. Doing a quick search there are a few people that have tried this and been successful. This may help get you started:
