Make Certain Items in Dropdown List Unselactable. Asp.net(vb)
Hi
I have a dropdown list populated by a data source.
Some of the items I want to be Greyed out and un-selectable. What's the best way to achieve this?

Simply filter them out of the datasource. Unless you have very special needs, providing a list in which some items cannot be selected is a very strange idea. The raison d'être of a DropDown is "here is what you can chose from", so it normally makes no sense to display items that are not selectable.
Jacques - its not a strange idea.....filtering them out is easy. You've missed the point.
The reason why I'd like to do this is that the dropdown list is data bound. Some of the options I do not want selected already exist in the database so I need them to be available to the dropdown if a selected record contains an old have I no longer want selectable when creating a new record.

To the best of my knowledge - not possible. It is either ALL are available or NONE. The best you could do is prevent a new record being added when the user attempts to save it.
