SelectedItem and Intellisense

Hi i'm new to this :)

My question might be simpel but i can't find the result.

The question is why doesn't intellisense show SelectedItem (Value(index))

an example:

if (dropdownlist.SelectedItem.Tekst = "true")

{

do something

}

so in the if statement intellisense won't show SelectedItem and VS2013 (Express) gives a debug Error

At least thank you for your reply's

Kind regards
