set my model with viewbag value

Within a form I populate my output model (that will be handled by the controller). One value is not a user input, it is actually an object from previous page I injected with Viewbag to this page. Now I want to set this object to one of my model properties (complex object) and I'm looking for a way to do it. I encountered 

  @Html.HiddenFor(m =>

But I can't seem to understand how to set my propery there

If the property is available in the ViewBag object, then you could do this.

public ActionResult Index()
{
    var viewModel = new YourViewModelClass();

    viewModel.Property = ViewBag.Property;

    return View(viewModel);
}

[HttpPost]
public ActionResult Index(YourViewModel viewModel)
{
    // viewModel.Property will contain the hidden input value.
}

View

@Html.HiddenFor(m => m.Property);

This way, you keep the value from the ViewBag inside your viewmodel when it is posted back to the server.

As per my understanding, You can not use HiddenFor without using a model.

You can try,

@Html.Hidden("FieldId", ViewBag.FieldId)

Access it in controller like

public ActionResult Action(string FieldId)
{
    //Do something
}
