Question

I’m trying to check if a certain node has a property “footerTextTitle” by:

@foreach (var nodeLink in footerTop.ChildrenAsList.Where(n => n.GetProperty("footerTextTitle").IsNull() == true))
  {
    <li><a href='@nodeLink.GetProperty("footerLinkUrl").Value.ToString()'>@nodeLink.GetProperty("footerLinkTitle").Value.ToString()</a></li>
  }

and getting a “Object reference not set to an instance of an object.” error.

How can I do this ?
Thanks.

Answer 1

To check if a property exists simply check if the property is null like below

@foreach (var nodeLink in footerTop.ChildrenAsList.Where(n => n.GetProperty("footerTextTitle") == null))
  {
    <li><a href='@nodeLink.GetProperty("footerLinkUrl").Value.ToString()'>@nodeLink.GetProperty("footerLinkTitle").Value.ToString()</a></li>
  }

P.S. To debug, append this to the url
