Shorthand for creating a ViewDataDictionary with both a model and ViewData items?

Question

Is there any way to create a ViewDataDictionary with a model and additional properties with a single line of code. I am trying to make a RenderPartial

Answer 1

I created an extension method on HtmlHelper to copy the property names and values from an anonymous object to a ViewDataDictionary.

Sample

Html.RenderPartial("SomePartialView", MyModelObject, new { SomeDisplayParameter = true })

HtmlHelper Extension

public static void RenderPartial(this HtmlHelper htmlHelper, string partialViewName, object model, object viewData)
{
    var vdd = new ViewDataDictionary(model);
    foreach (var property in viewData.GetType().GetProperties()) {
        vdd[property.Name] = property.GetValue(viewData);
    }
    htmlHelper.RenderPartial(partialViewName, vdd);
}
