Create another class which contains your strongly typed class   Add your new stuff to the class and return it in the view   Then in the view  ensure you inherit your new class and change the bits of code that will now be in error   namely the references to your fields   Hope this helps   If not then let me know and I ll post specific code

RenderPartial takes another parameter that is simply a ViewDataDictionary  You re almost there  just call it like this   Html RenderPartial         ProductImageForm           image          new ViewDataDictionary      index   index           Note that this will override the default ViewData that all your other Views have by default   If you are adding anything to ViewData  it will not be in this new dictionary that you re passing to your partial view

To extend on what womp posted  you can pass new View Data while retaining the existing View Data if you use the constructor overload of the ViewDataDictionary like so   Html RenderPartial         ProductImageForm           image          new ViewDataDictionary this ViewData       index   index

The easiest way to pass additional data is to add the data to the existing ViewData for the view as  Joel Martinez notes   However  if you don t want to pollute your ViewData  RenderPartial has a method that takes three arguments as well as the two-argument version you show   The third argument is a ViewDataDictionary   You can construct a separate ViewDataDictionary just for your partial containing just the extra data that you want to pass in
