    Render PartialView (UmbracoTemplatePage) from Macro (PartialViewMacroPage)?

    Hi,

    Im trying to render a partial view from inside a macro.

    The macro is registered in the back-office, and has one parameter. The macro is supposed to be available from RTE's.

    The macro is based on a partial view, located in ~/Views/MacroPartials, that inherits Umbraco.Web.Macros.PartialViewMacroPage. Tha macro works, and the parameter gets populated as it's supposed.

    In the macros partial, i want to render a partial that i'm already using on the site - from various templates. The Partial inherits Umbraco.Web.Mvc.UmbracoTemplatePage and is rendered with @RenderPage() with three arguments on top of the path and model. However, when i'm including the Partial with RenderPage, i get an error message telling me:

    The model item passed into the dictionary is of type 'Umbraco.Web.Models.PartialViewMacroModel', but this dictionary requires a model item of type 'Umbraco.Web.Models.RenderModel'.

    I guess that's reasonable, but still, i need to render the Partial from the Macro. How would you approach the problem? Can i change the inheritance in the Partial to make it play nice? What would that be?

    Hi Anders,

    I would have your Partial View expect a model of IPublishedContent instead of RenderModel, then it can be easily used from both a view and a Partial View Macro.

    e.g.

    Partial View:

    @inherits UmbracoViewPage<IPublishedContent>
@{
    var myHomePage = Model.AncestorOrSelf(1);
}

    Then it can be called from either View or Macro:

    @Html.Partial("MyPartial", Model.Content)

    Got it working passing the params with a ViewDataDictionary.

    For future reference:

    var viewDataDictionary = new ViewDataDictionary
{ 
   {"items", items}, 
   {"count", count}, 
   {"heading", heading}
};

@Html.Partial("~/Views/Partials/FeedItems.cshtml", Model.Content, viewDataDictionary)

    And accessing the params in the partial as follows: 

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<IPublishedContent>
@{
   var items = (IEnumerable<IPublishedContent>)ViewData["items"];
   var count = (int)ViewData["count"];
   var heading = (string)ViewData["heading"];
}

    ... works from both templates and macro partials.

    Thank you for your help!
