I used the same Code and it worked for me. Check your Choice Field I think You Might forgot to add Choices in your Choice Field.

I used Code from Shobha's Blog and it is also working.

you can try this:

        Guid siteId = SPContext.Current.Site.ID;
             using (SPSite site = new SPSite(siteId))
                 using (SPWeb objSPWeb = site.RootWeb)
                     SPList objSPList = objSPWeb.Lists["Department"];

                     SPFieldChoice field = (SPFieldChoice)objSPList.Fields["mobile"];
                     DropDownList1.DataSource = field.Choices;

very similar to yours, as i think yours work, maybe its the user your using? so iv wrapped it into a runwithelevatedpriv

hope it helps :)

I dont know why iv been marked down as its perfectly fine to wrap a spsecurity as the user the op could be using could not have access to the list that they want to get the mobile colum from! –  ali Sharepoint Dec 29 '12 at 11:03

if my answer is correct please mark it as correct so others know the answer two when they come up with the same issue :) thanks –  ali Sharepoint Dec 31 '12 at 23:38

I found that for some reason the following code:

drop_dept.DataSource = filed.Choices;

always makes drop_dept.SelectedItem refer to the first element on the list regardless the item actually selected.

Replacing it with:

foreach (string choice in filed.Choices)

solved my problem.
