I would like to toggle the visibility of the DropDownList control based on wether is has items or not. The user enters an ID number that runs a query against a DB and populates the DropDownList based on the informaiton that it acquires. The DropDownList starts with its visibility set to False. How can I create a code-behind that will check wether the control has been populated or not and set its visibility accordingly?
