[Required(AllowEmptyStrings = false)]
public string MigraineTypeId { get; set; }

Hi Patrick,

Thanks for your patience

We checked your query and we would like to inform that data operation and CRUD operation will perform properly only for Field enabled GridColumn. But in your sample you want to perform CRUD operation in template column.  Hence the reported issue occurred.

So we also suggest to define Field property to the Gridcolumn to perform column validation properly in that column. Please get back to us if you have any further queries
