Base dropdownlist of a viewbag value

Question

Hi, i have a viewbag.Site being collected from the Active Directory, basically i am returning an id which is just a number. I am trying to figure out how best to return a description of in a textbox on my view. Viewbag.Site = 3 then 'A' else 'B' kind of thing, so far i have used a Json dropdown change function select list, however as the value has already been collected it does not trigger the dropdownlist. I need it to be a dropdownlist so people can still change the site but it auto picks up the site they are based. I would be grateful for any adivce thanks

public ActionResult Index() { MyModel myModel = new MyModel(); PrincipalContext context = new PrincipalContext(ContextType.Domain); UserPrincipal user = UserPrincipal.FindByIdentity(context, User.Identity.Name); DefaultVars defaultVars = new DefaultVars(); string UserName = User.Identity.Name.Replace(@ "DOMAIN\" , string .Empty); myModel = defaultVars.retVars(user, UserName); ViewBag.UserName = user.Name; return View(); } My view @ using (Html.BeginForm()) { class = "row" > class = "col-lg-11" > class = "input-group" > class = "input-group-addon" > class = "glyphicon glyphicon-user" > @Html.TextBox( "Site" , ( string )@ViewBag.SiteId, null , new { @ class = "form-control" }) class = "row" > class = "col-lg-11" > class = "input-group" > class = "input-group-addon" > class = "glyphicon glyphicon-user" > @Html.DropDownListFor(x => x.Hospital, new SelectList( string .Empty, "Value" , "Text" ), "Please select a Hospital" , new { @ class = "form-control" }) }

hi yes so the viewbag will just have a 3 or 4 etc in depending on the site, i have got this value from the active directory. I then need a dropdown list that will be defaulted to the viewbag results as a description so in this instance 3 = "A". the dropdownlist result needs to be binded to the Hospital in a textboxFor and the user needs to be able to override the defaulted selection with other options as well Thank you for your reply, i hope i have explained well enough.

Hi Michelle M, I little query about to where is store data and stored data is globally. Please correct me if am take wrong direction. As per my understanding you need to a store data in object after page ready. I assume in object have couple of data. var person = { Site: "3" , lastName: "Doe" , age: 50, eyeColor: "blue" }; before call just check dropdown selected value is there or not. Waiting Thanks Joginder signh
