Setting Selected Value of DropDownList in MVC 3

I have gone through numerous methods of trying to set the value of a dropdownlist and must be doing something silly because none of the methods are working.

@Html.DropDownList("startTime", @Model.startTimeList, new { @class = "startTime", style = "width: 100px;" })

Its a generated list of half hour increments.

In my controller I set this string value..

model.startTime = myTime + " " + amOrPm;  //ex 10:30 PM

My List looks like this.

List<SelectListItem> startTimeList = new List<SelectListItem>();    

SelectListItem time12 = new SelectListItem { Text = "12:00 PM", Selected = false, Value = "12:00PM" };
startTimeList.Add(time12);

SelectListItem time12Half = new SelectListItem { Text = "12:30 PM", Selected = false, Value = "12:30PM" };
startTimeList.Add(time12Half);

My list always defaults to 12:00 PM because its the first one entered into the list. I want that if model.startTime has a value it sets to that value.

You can use DropDownListFor and let the Razor engine do the work of selecting the item that matches the property.

@Html.DropDownListFor(model => model.startTime, startTimeList)

The alternative would be to explicitly set Selected on the item that matches:

startTimeList.First(item => item.Text.Equals(model.startTime)).Selected = true;

If you have a startTime property on your model, and the value of that property matches one of the values in the list (ie, it matches "12:00PM", or "12:30PM" but not "12:00 PM" or "12:30 PM"), then I think this should work:

@Html.DropDownListFor(model => model.startTime, 
    @Model.startTimeList, 
    new { @class = "startTime", style = "width: 100px;" })
