How to prevent duplicates when using on the dropdown box feature	2/9/2010 2:30:15 PM
ASPRunnerPro General questions
B bramo author I have a situation where users can choose the company name from the dropdown box or add it on the fly. How can I prevent duplicates entered and display some kind of message that the company name already exist when using Add on the fly feature of the dropdown box? I'm using AsprunnerPro 6.0

	Hi, use Before record added event on the Eventstab to check entered values and show error message if needed. Use Check if specific record exist action as a sample.
