Object null reference error MVC4

Question

I have a viewmodel as:

public class AutoAdvert
{        
//
    public Condition condition { get; set; }
}

But when I access it in view it gives null reference error.

<div class="editor-label">
    @Html.LabelFor(model => model.condition.Tyres)
</div>
<div class="editor-field">
    @Html.TextBoxFor(model => model.condition.Tyres)
</div>

Where I am paasing to view:

public ActionResult autoadvert()
        {
            AutoAdvert autoadvert = new AutoAdvert();

            return View(autoadvert);
        }

I'll assume your `condition` is `null`. What does the debugger say? Where do you set its value? — Jeroen Vannevel, Aug 20 '13 at 09:51
Yes, but does the model being sent to your view actually contain an instantiated `condition`? — Jeroen Vannevel, Aug 20 '13 at 09:55
That means it has a `null` value. Please edit your post and include the code that shows where you send the model to the view. — Jeroen Vannevel, Aug 20 '13 at 09:58
Added the constructor and initialized the condition class object but still same exception — Ali Shahzad, Aug 20 '13 at 10:09

Your Condition is null. Add a Constructor to the autoadvert class and assign something to the variable.

public class AutoAdvert
{        
//
    public AutoAdvert(){
        Condition = New Condition();
    }
    public Condition condition { get; set; }
}

And you have to do the same thing in the Condition class to the Tyres if they are classes because the are null.

I suppose you have forgotten to initialize the class Condition while populating the model class AutoAdvert
