Question

Hi,

I have some code that inserts the value of a dropdown into th database. However when coming back to the page, it doesn't preselet the option that was selected before the update.

My View Model is like so:

        //Dropdown options
        private string _selectedIncoTerm;

        public IList<BTBLL.INCOTerm> IncoTerms { get; set; }

        public string SelectedIncoTerm
        {
            get
            {
                if (String.IsNullOrWhiteSpace(_selectedIncoTerm) && IncoTerms != null)
                {
                    _selectedIncoTerm = IncoTerms.First(x => x.DefaultOption).Code;
                }

                return _selectedIncoTerm;
            }

            set { _selectedIncoTerm = value; }
        }

In my Controller action i do this to set the value:

IncoTerms = _incoTerms.FindAll()

Then in my view i have this:

@Html.DropDownListFor(x => x.SelectedIncoTerm, incoTypes, null)

Can you see anything obvious that i am doing wrong?

Many thanks,
