Can a text box be validated against a database field for a unique name. (just like when registering usernames for dnn core)
I have a form where users sign up and create a group. The group input is a text box. I need the box to validate against the existing lists of group names in the dababase so that if a user inputs one that already exists.. the form will warn them that they need to select another name.
Is this possible... if so please point me in the right direction.
