Using GetProperty-value in while loop
I am trying to create a Left Navigation Menu macro, using razor. I've run into one small issue though.

Consider my code
```
@{
    var rootnode = Model;
    while (rootnode.Level > 2 && !(bool)rootnode.GetProperty("rootnode")){
        rootnode = rootnode.Parent();
    }
}
```
As you can see, it keeps going up from the own page until the level is 2 or the property "rootnode" is true.

On level 2 pages, this works. But on level 3 pages i get this error:
```
Error loading MacroEngine script (file: Leftnav.cshtml)
```
What am i doing wrong here, and how do i solve it?

I was able to solve it. I looked at the type that GetProperty returned, and figured i used the wrong method. After some documentation searching i found the GetPropertyValue, which returns a string value. Is Razor using lazy evaluation? I figured that could be why i worked on level-2 nodes...

Hi Anton

Not 100% sure what you are trying to create, but if you are using 4.11.1 MVC, you can achieve a breadcrumb type navigation by:

@CurrentPage.Up().NiceUrl()

If you want full navigation, try

@{

var updates = CurrentPage.AncestorOrSelf().Descendants();

}

foreach (var item in updates)

{

<a href="@item.NiceUrl()">@item.Name</a>

}

This will give you a list.

Hope this points you in the right direction.

Thank you for your reply Gary.

Actually its for i side bar navigation. I wanted the children shown in the menu to be the children of the closest mode where the property "rootnode" is set to true. I was able to solve it according to my reply above.

just in case you weren't aware... add ?umbDebugShowTrace=true to your url and make sure your web.config setting has debug enabled.
```
 <add key="umbracoDebugMode" value="true" />
```
Then you can get an error message that is a little more descriptive than the Error loading MacroEngine script (...)
