Is it possible to disable an item in a dropdownlis

Question

Can I disable an item in a dropdownlist in c#?

For example, I have 2 dropdownlist combobox. Both of them consist of months (jan, feb, mar, apr, etc....) and both of them will function like a range of month in a certain year. When I choose apr on the 1st combobox, the second combobox can't choose jan, feb, mar

Answer 1

Yes you can.

ListItems in your dropdownlist have an Enabled property. You can set this to false to disable them.

EDIT:

Sorry I made the assumption you were using WebForms (ASP.Net). For windows forms, you can take a look at this answer: Create WinForms ComboBox with non-selectable items - its the same principle but with some slight implementation details because Combobox Items collection is one of objects. Dropdownlist (the Web form equivalent) uses typed 'ListItem' objects.

HTH.
