Not showing selected value of one drop down list in another of a gridview

samrat399 asked:

Hello guys, I have a gridview with dropdown lists in them. I want the selected value from the dropdownlist to not appear in the next dropdown list.

How can I go about this problem. Links to code and suggestions are most welcome.

Eg : Suppose I have a drop down list for Cities. If I select 'Mumbai' from the first drop down list then 'Mumbai' should not appear in the next drop down list.
