Asp.net-mvc – Access Parent Model from partial view

asp.net-mvcasp.net-mvc-3partial-viewsrazor

I'm asking because the partial view I will create is blank, with the purpose of creating a new child entity. I just need a quick, regardless if dirty, way to access the Parent Model from within the partial view. I need the Id of the parent.

Does a partial view automatically have access to the model of the parent?

You cannot access the parent model from a partial view unless you pass some value to this partial as parameters when rendering it. For example in your main view:

@model MyViewModel
...
@Html.Partial("_myPartial", new ViewDataDictionary(new { id = Model.Id }));

and then inside your partial you could access the Id:

<div>@ViewBag.Id</div>

Of course this is a pretty lousy way of passing data to a partial view. The correct way is to use a strongly typed view model.
