    copied!<p>I have a site that was using ASP.Net MVC Beta 5, and I have just upgraded it to ASP.Net MVC 1.0. I am having trouble with the selected item in a drop down list.</p> <p>The follow person has a similar question (<a href="https://stackoverflow.com/questions/589935/html-dropdownlist-in-asp-net-mvc-rc-refresh-not-pre-selecting-item">Html.DropDownList in ASP.NET MVC RC (refresh) not pre-selecting item</a>) but I there is no answer (other than it might be a bug)</p> <p>My Controller method looks as follows:</p> <pre><code>[AcceptVerbs(HttpVerbs.Get)] public ActionResult View(Guid id) { IntegrationLogic logic = new IntegrationLogic(new IntegrationLinq()); CompanyLogic companyLogic = new CompanyLogic(new CompanyLinq()); IntegrationContainer container = new IntegrationContainer(); container.Sources = logic.GetImportSource(id); container.Companies = companyLogic.GetCompanies(); // Returns a IList&lt;company&gt; container.SourceActions = logic.GetAllSourceActions(); // Returns an IList&lt;SourceAction&gt; container.SinkActions = logic.GetAllSinkActions(); container.SuccessActions = logic.GetAllSuccessActions(); container.FailureActions = logic.GetAllFailureActions(); container.Actions = logic.GetAllActions(); container.Watchers = logic.GetAllWatcherActions(); container.ChainActions = logic.GetAllChainActions(); return View("View", container); } </code></pre> <p>The view is a strongly typed against the Model as follows</p> <pre><code>public partial class View : ViewPage&lt;IntegrationContainer&gt; {} </code></pre> <p>The problem area in the view template is :</p> <pre><code> &lt;label for="Companies"&gt;Company: &lt;/label&gt;&lt;%=Html.DropDownList("Companies", new SelectList(ViewData.Model.Companies, "id", "name", item.CompanyID))%&gt; </code></pre> <p>I am creating a Dropdown List, the selected item never actually gets selected - and that is the problem. "item.CompanyID" is a Guid, "id" is a Guid and "name" is a string on the company object supplied in the IList that is held in the ViewData.Model.Companies instance.</p> <p>Is this actually a bug ?- I find it hard to understand why this is still present in ASP.Net MVC... I would be totally happy if it is something I have done.</p> <p>Regardless, what would be the suggested work around? </p> <p>Thanks</p>
