Error when passing additional ViewData to strongly typed Partial View

Question

My partial view isn't being loaded. Please find my code snippets, I can't figure out what is wrong. Help please.

The error message is:

c:MvcUI\Views\Project\Details.ascx(42): error CS1950: The best overloaded Add method 'System.Web.Mvc.ViewDataDictionary.Add(System.Collections.Generic.KeyValuePair)' for the collection initializer

I am having In my view:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MvcUI.Models.ProjectModel>" %><%Html.RenderPartial("LabelsDetails", Model.Categories, new ViewDataDictionary{"labelsName", labelsName }); %>

My partialView

<%@ Control language="C#"Inherits="System.Web.Mvc.ViewUserControl<Models.ProjectModel>" %> <%int count = 0; %> <%var labelsName = ViewData["labelsName"];%> <%if (Model!=null) {%> <%if (!String.IsNullOrEmpty(Model.Name)) {%> <li> <%: Html.Hidden((labelsName)+".Index", count.ToString())%> <%: Html.TextBox((labelsName)+"[" + (count) + "].Name", Model.Name, new { Style = "width:280px" })%> <%: Html.Hidden((labelsName)+"[" + (count++) + "].ID", Model.ID, new { Style = "width:280px" })%> <input type="button" value = "Delete"/> </li> <%} %> <%} %> <li> <%: Html.Hidden((labelsName) + ".Index", count.ToString())%> <%: Html.TextBox((labelsName) + "[" + (count) + "].Name", "", new { Style = "width:280px" })%> <%: Html.Hidden((labelsName) + "[" + (count++) + "].ID", 0, new { Style = "width:280px" })%> <input type="button" value= "Add" /> </li>

My projectModel

public class Label { public String Name { get; set; } public int ID { get; set; } } public List<Label> Categories { get; set; }

The syntax you are using to initialize the ViewDataDictionary is wrong. You need two {. Try like this:

<% Html.RenderPartial( "LabelsDetails", Model.Categories, new ViewDataDictionary {{ "labelsName", labelsName }} ); %>
