Cannot access ViewData in partial view in ASP.NET MVC3

Question

I have a controller that calls a view. The view has a partial view inserted as follows:

@{ Html.RenderPartial("PartialViewName", this.Model);}

This works great.

But in the controller, I want to put something in the ViewData or ViewBag, which I will use in a partial view. How can i do this?

@{ Html.RenderPartial("_MyPartial", Model.Property, new ViewDataDictionary { ... });}

@{ Html.RenderPartial("_MyPartial", Model.Property, ViewData);}

, ViewBag - .

EDIT:

ViewBag ViewData, , , /. , :

@{ ViewBag.MyNewValue = "..."; }
@Html.Partial("_MyPartial", Model)

@{ string myString = ViewBag.MyNewValue; }

You can do this in the easiest way.

Just install Viewbag.sth = value;in your controller.

and with partial use @ViewBag.sth

As others have said, as long as you assign a ViewBag value in your action method, you must have access to it in your partial view.

In addition, you should be able to display a partial block as follows:

@Html.Partial("PartialViewName", Model)

instead of this

@{ Html.RenderPartial("PartialViewName", this.Model);}.
