Is there any combination of calls I can use to make a dropdownlist's text+value blank again after the first time it has been selected? The reason being that I am using a data source to change the options available to the list, and I want the user to know that they have to select a new option when the list's contents change. Currently, it keeps the text of the last selection, even if its option is no longer present in the list.
Does anyone have any possible solutions to this problem?
