The Value attribute of all items (exxcept 325) is set to "0", so I'm not surprised that the value you get is always 0. Set the Value attribute for any item to something unique and identifiable.

[Edit]

Ah, so the index is always 0, not the value?

I would still try to change the 'Value' attributes. It's likely that ASP.NET derives the index based on the Value posted in the request (so, ASP.NET sees a Value of zero, performs indexing, and finds out that the first dropdownlist element has value zero, so the index is zero). If that's the case (and I think it is, because web browsers send the selected Value in a request, not the selected index), unique Values will lead to a correct index.

Dropdownlist always return value of '0' index.
