    Html.Partial Model and ViewDataDictionary

    When you create a Partial you can pass the Model (IPublishedContent) into the partial or you can pass a ViewDataDictionary in there.

    However i thought you could pass both as the API has the following method:

    Html.Partial(string PartialViewname, object Model, ViewDataDictionary<T> viewData)

    But if i pass in the Model.Content AND a view data and my model inherits from UmbracoViewPage<IPublishedContent> the view is expecting a ViewDataDictionary of type IPublished content.

    I looked at doing soemthing like this but it doesnt like it. The ViewData datas its of type string but thinks its an object and @Model.Name is invalid as it thinks Model is a string.

    @model IPublishedContent
@inherits UmbracoViewPage<string>
@{
    string colour = ViewData["colour"];
}
Name = @Model.Name

    Slightly confused now as im sure ive passed in both before.

    Can anyone clear this up?

    Like this I believe:

    Html.Partial("MyPartial", myModel, new ViewDataDictionary{ {"colour", "green" } });

    Not 100% sure but your first issue might be just that you need to cast to a string rather than assign it.  So rather than:

    string colour =ViewData["colour"];

    Try:

    var colour =ViewData["colour"].ToString();

    Or:

    var colour = (string)ViewData["colour"];

    Doh! Damn intellisense! :)

    I was going on what the intellisense was giving me.

    Done just this and it works fine. :)

    @inherits UmbracoViewPage<IPublishedContent>
@{    
    var colour = (string)ViewData["colour"];
}

    Thanks Andy.
