Nullchecks on Field Property Column

Radzen.Blazor Components
1

Hello,

I dynamically add columns to my RadzenTable
And I have a question regarding filling in the Field property on a Column item.

This is my field property of my Column object:
Field = (x => x.MyList.FirstOrDefault(c => c.MyItem.Id == Id).MyProp),

I would like to do null checks on this since whenever I run my app and it doesn't find that Id it will crash with a null reference since it can't get the MyProp from that Item.

So I tried this,
Field = (x => x.MyList.FirstOrDefault(c => c.MyItem.Id == Id)?.MyProp),
but you can't do this since:
CS8072 - An expression tree lambda may not contain a null propagating operator.

I then looked a bit further on the internet and tried to do this which doesn't give errors on a build:
Field = (x => x.MyList.FirstOrDefault(c => c.MyItem.Id == Id) == null ?
x.MyList.FirstOrDefault(c => c.MyItem.Id == Id).MyProp : "")

But when running the code it gives me this exception:
System.InvalidCastException: 'Unable to cast object of type 'System.Linq.Expressions.FullConditionalExpression' to type 'System.Linq.Expressions.UnaryExpression'.'

Any way I can do null checks on this Field property with using a UnaryExpression or an alternative way?

Thanks in advance

I’m afraid that we don’t have such component (RadzenTable) nor columns with Field property.

Hello Enchev,

Yes sorry, I'm retarded. I was using an inferior Tablepackage before and was in the process of moving over to RadzenTable. This was an issue with the inferior TableLibrary. Sorry to have bothered you with this.
