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.
