Question

I want to show the stored values in dropdown as a selected value. I dont know how to do this in MVC.

My code is

<%: Html.DropDownList("basic-qualification-container" + i.ToString(), 
         new SelectList((IEnumerable<Dial4Jobz.Models.Degree>)ViewData["CandidateBasicQualifications"], "Id", "Name", (IEnumerable<int>)ViewData["BasicQualificationDegrees"]), 
         new { @class = "qualification" })%> 

I select some option from dropdown and submit. After I load the page the last stored value will display. This is my problem.

Answer 1

DropDownList Helper in SomeAction View

Html.DropDownList(
    string name,
    IEnumerable<SelectListItem> selectList,
    ViewData["lastSelected"],  // String Selected Option
    object htmlAttributes) 

You can show selected value with viewData like below.

Controller

// Set Default selected
public ActionResult SomeAction()
{
    ViewData["lastSelected"] = "Default Text";
    return View();
}

And after post, you should set again viewData that is shown in selected value.

// Set selected value after posting
[HttpPost]
public ActionResult SomeAction()
{
    .....
    ViewData["lastSelected"] = "Changed Text (selected value)";
    return View();
}
