In MVC to be able to get a EPiServer property and make it editable in the on-page-edit I normally use @Html.PropertyFor(m => m.CurrentPage.PageName). But in some cases, eg on the _Root.cshtml I am not sure if a specific property exists, therefor I want to use the code below:

@if (Model.CurrentPage["PageName"] != null) 
{     
   @Html.PropertyFor(m => m.CurrentPage["PageName"]) 
}

But when I run this I got this exception:

Unsupported expression. The body of the expression must either be a MemberExpression or a UnaryExpression. On the PropertyFor-row.

Isn't this possible? I am new to MVC so maybe I am doing it totally wrong?

Try this one:

<div @Html.EditAttributes("PageName")>@Html.Display("PageName")</div>

Hi Valdis,

I have tried this and Html.EditAttributes is getting the on-page edit working perfectly, however Html.Display is always rendering nothing. Any idea why?

Try output just property value: @CurrentPage["PageName"]. Does it renders some content? What data type is for the property that is not rendering?
