Support null columns on grid

I'm currently working on ASP.Net Core MVC app with Telerik Kendo 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?

Solution

You have to use ClientTemplate:

columns.Bound(x => x.PrimaryContact.EmailAddress)
       .ClientTemplate("#=PrimaryContact ? PrimaryContact.EmailAddress : ''#")
