    text
    copied!<p>I have an import page with a dynamic number of transactions. For each transactions, I have several plain text data labels and one DropDownList (Categories). I'm trying to populate this <code>Category</code> DropDownList with data from my ViewModel (<code>Categories</code>) by passing the Categories Model as additionalViewData to my EditorTemplate.</p> <p>When I use the example below, I get the following error on the EditorTemplate page: Compiler Error Message: CS0411: The type arguments for method 'System.Web.Mvc.Html.SelectExtensions.DropDownListFor(System.Web.Mvc.HtmlHelper, System.Linq.Expressions.Expression>, System.Collections.Generic.IEnumerable)' cannot be inferred from the usage. Try specifying the type arguments explicitly.</p> <p>Any ideas on how to fix this?</p> <p>ViewModel:</p> <pre><code>public class ImportViewModel { public List&lt;AbnAmroTransaction&gt; AbnAmroTransactions { get; set; } public IEnumerable&lt;SelectListItem&gt; Categories { get; set; } } </code></pre> <p>Model:</p> <pre><code>public class AbnAmroTransaction { public string Currency { get; set; } public int DateTime { get; set; } public string Description { get; set; } public int CategoryId { get; set; } } </code></pre> <p>Form:</p> <pre><code>@using (Html.BeginForm("ImportPreview", "Home", FormMethod.Post)) { &lt;table&gt; @Html.EditorFor(m =&gt; m.AbnAmroTransactions, new { Categories = Model.Categories }); &lt;/table&gt; &lt;input id="btnSave" type="submit" value="Save data" /&gt; } </code></pre> <p>EditorTemplate:</p> <pre><code>&lt;tr&gt; &lt;td style="width: 80px;"&gt; @Html.Raw(CurrencyHelper.GetHtmlCurrency(Model.Currency, Model.Amount)) &lt;/td&gt; &lt;td&gt;@Model.DateTime&lt;/td&gt; &lt;td&gt;@Model.Description&lt;/td&gt; &lt;td&gt;@Html.DropDownListFor(Model.CategoryId, ViewData["Categories"])&lt;/td&gt; &lt;/tr&gt; </code></pre>

Guidance
An individual column

Larger individual text columns get their own page to allow for proper reading.
