  1. POSelected Item in Dropdown Lists from Enum in ASP.net MVC
    text
    copied!<p>Sorry if this is a dup, my searching turned up nothing.</p> <p>I am using the following method to generate drop down lists for enum types (lifted from here: <a href="http://addinit.com/?q=node/54" rel="noreferrer">http://addinit.com/?q=node/54</a>):</p> <pre><code>public static string DropDownList(this HtmlHelper helper, string name, Type type, object selected) { if (!type.IsEnum) throw new ArgumentException("Type is not an enum."); if(selected != null &amp;&amp; selected.GetType() != type) throw new ArgumentException("Selected object is not " + type.ToString()); var enums = new List&lt;SelectListItem&gt;(); foreach (int value in Enum.GetValues(type)) { var item = new SelectListItem(); item.Value = value.ToString(); item.Text = Enum.GetName(type, value); if(selected != null) item.Selected = (int)selected == value; enums.Add(item); } return System.Web.Mvc.Html.SelectExtensions.DropDownList(helper, name, enums, "--Select--"); } </code></pre> <p>It is working fine, except for one thing. If I give the dropdown list the same name as the property on my model the selected value is not set properly. Meaning this works:</p> <pre><code>&lt;%= Html.DropDownList("fam", typeof(EnumFamily), Model.Family)%&gt; </code></pre> <p>But this doesn't:</p> <pre><code>&lt;%= Html.DropDownList("family", typeof(EnumFamily), Model.Family)%&gt; </code></pre> <p>Because I'm trying to pass an entire object directly to the controller method I am posting to, I would <em>really</em> like to have the dropdown list named for the property on the model. When using the "right" name, the dropdown does post correctly, I just can't seem to set the selected value.</p> <p>I don't think this matters but I am running MVC 1 on mono 2.6</p> <p><strong>edit:</strong> I just tested this on windows, and I am seeing the same behavior</p>
