I'm currently working on ASP.Net Core MVC app with [Telerik Kendo Grid](https://www.telerik.com/aspnet-core-ui/grid)

On the grid I have columns like:

```
 .Columns(columns =>
                    {
     columns.Bound(x => x.PrimaryContact.EmailAddress)
  })

```

But this is throwing an error:

> 
> Uncaught TypeError: Cannot read properties of null
> 
> 
> 

Because PrimaryContact property can be null

To solve this I try:

```
columns.Bound(x => x.PrimaryContact != null ? x.PrimaryContact.EmailAddress : string.Empty)

```

But now is returning the error:

> 
> InvalidOperationException: Bound columns require a field or property
> access expression.
>

How can I support nullable in kendo columns?
