    copied!<p>I create a DropDown with the Html.DropDownList(string NameSelectListInViewData) method. This generates a valid Select input with the correct values. And all is well.</p> <p>Upon submit however, the value in the source SelectList is not bound. </p> <p><em>Case:</em> ViewData.SearchBag.FamilyCodes:</p> <pre><code>public SelectList FamilyCodes { get; set; } </code></pre> <p>Html that generates the dropdown:</p> <pre><code>&lt;%=Html.DropDownList("SearchBag.FamilyCodes")%&gt; </code></pre> <p>Generated html:</p> <pre><code>&lt;select id="SearchBag.FamilyCodes" name="SearchBag.FamilyCodes"&gt; &lt;option value=" "&gt;Any&lt;/option&gt; &lt;option value="A"&gt;BLUE&lt;/option&gt; &lt;option value="B"&gt;BLACK&lt;/option&gt; &lt;option value="C"&gt;BEIGE&lt;/option&gt; &lt;option value="G"&gt;GREEN&lt;/option&gt; &lt;option value="O"&gt;ORANGE&lt;/option&gt; &lt;option value="P"&gt;PURPLE&lt;/option&gt; &lt;option value="R"&gt;RED&lt;/option&gt; &lt;option value="S"&gt;GRAY&lt;/option&gt; &lt;option value="U"&gt;BROWN&lt;/option&gt; &lt;option value="W"&gt;WHITE&lt;/option&gt; &lt;option value="Y"&gt;YELLOW&lt;/option&gt; &lt;/select&gt; </code></pre> <p>In my controller I have an action with a parameter searchBag.</p> <pre><code>public ActionResult AdvancedSearch(SearchBag searchBag) { //Do Stuff with parameters in searchBag return View("AdvancedSearch", searchViewData); } </code></pre> <p>All other fields bind just fine, only the selection boxes don't. Any ideas?</p> <p><em>UPDATE</em><br> For future readers it might be worth it to read this blog post: <a href="http://haacked.com/archive/0001/01/01/model-binding-to-a-list.aspx" rel="nofollow noreferrer">http://haacked.com/archive/0001/01/01/model-binding-to-a-list.aspx</a></p>
