don't put [Required] on its viewmodel property, or if the type is int/long make it int? or long? (make it nullable), value types always need to have value

Thanks you, it works now. I've been using Awesome grid for a while but I'm still not clear about the use of Key = "Id". When should I use it and where the value of Id come from?

the key is needed most of the time (when using EF, grid api, nesting), so just set it all the time, the value of the Id comes from the grid model, GridModelBuilder<Model> originally and if you're using Map, the result type from the Map function
