Hi Marrix

Allways use

@inherits Umbraco.Web.Mvc.UmbracoViewPage 

And if you use ModelsBuilder use:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<someclass> 

You don't need UmbracoTemplatePage with latest Umbraco, it contains the same methods but with Dynamics support.

UmbracoTemplatePage is mostly a convenience, it is the same as UmbracoViewPage

Really great explanations here - https://our.umbraco.org/forum/developers/api-questions/52597-What-is-the-difference-between-UmbracoViewPage-and-UmbracoTemplatePage

Thanks,

Alex

Probably the best explanation is this article - https://24days.in/umbraco-cms/2015/strongly-typed-vs-dynamic-content-access/ by Dave Woestenborghs

Personally, I always try to use the UmbracoTemplatePage in my views. However if I require a model that isn't based on a render model, then I resort to the UmbracoViewPage. This is normally in partial views rather than main templates.

With the introduction of Models Builder, unless my partial is handling a variety of IPublishedContent, I always specify the model in the type section for the UmbracoTemplatePage.

UmbracoTemplatePage has a default model that contains an IPublishedContent which is accessed via Model.Content, however when you've specified a type Model.Content is of that type instead.

In UmbracoViewPage Model is the type you specify, I'm not sure what it defaults to if you don't specify a type with it as I don't think I've used it in that way before.

Thanks, both of you :-)

For now, I'm trying to understand UmbracoViewPage and how it handles the generic models across the different "layers". E.g. I have tried this:

Master.cshtml (containing head, header, main-menu, footer) - not allowed in root, but allows almost all other views as a child. And it has this include:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<Master>

My "homepage" Home.cshtml (child of master in Content) has this include:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<HomePage>

A partialview CategoryList.cshtml - used in Home.cshtml - containing some category-items has this include:

@inherits Umbraco.Web.Mvc.UmbracoViewPage

Q 1:

I have added @Model.Name to both my Master, Home and partial. They all return the text/name "Home". It makes sense for Home and partial. But my Master has no Name and I did expect some error. Why is its @Model.Name returning/"inheriting" the name of its child - the Home-page - but is still able to handle its own properties like @Model.Description as well?

Q 2: When my partial is including this:

@* ProductOverview is the parent of all categories*@
@inherits Umbraco.Web.Mvc.UmbracoViewPage<ProductOverview>

instead of just this:

@inherits Umbraco.Web.Mvc.UmbracoViewPage

I get this error: Cannot bind source content type Umbraco.Web.PublishedContentModels.HomePage to model type Umbraco.Web.PublishedContentModels.ProductOverview

Then how can I use a Model in a partial, when the containing page uses another Model? Is it not possible? Will I have to base a partials model on the containing views model?

Hi Nik,

HomePage and Master is connected like this:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<HomePage>

@{
    Layout = "Master.cshtml";

    //var backgroundImage = CurrentPage.coverPhoto;
    var backgroundImage = Model.CoverPhoto;
}

And on my HomePage, I call the partial like this:

    <div class="col-md-8">
        @Html.Partial("CategoryList");
    </div>

Hi Nik,

In doc.type Home is "a child" of Master - and inherit the properties from there.

Ahh ... I see :-) That explains it, I guess ...?

I have another partial on Home, where I send the Model into the partial like this ...

@Html.Partial("AdvBoxLayout", @Model.ChooseAdvBox)

I can do that, because ChooseAdvBox is a "content picker" property in Home-model. How can I enclose the ProductOverview-Model - which have no direct relationship to Home - from Home, where the Home-model rules, to the partial?

In the partial I do this (as works):

@* ProductOverview is the parent of all categories *@
@inherits Umbraco.Web.Mvc.UmbracoViewPage

@{
    var selection = Model.FirstChild("productOverview").Children("category");
    // var selection = Model.Children("category"); --> only if inherits Umbraco.Web.Mvc.UmbracoViewPage<ProductOverview>
}

... the line commented out with // is what I prefer. And if not possible - I would like to understand why ... :-)

is working on a reply...
