[ASP .NET] If the source contains a 'decimal' type, the grid will throw an error and not render

[IvanPeevski]

If the source of the jqxgrid contains a 'decimal' type, the automatically generated JS code will omit the value of this item property.

Example: If the source is made up of this object:

public record Model {
        public int Id { get; init; }
        public string Name { get; init; }
        public decimal Budget { get; init; }
        public DateTime StartDate { get; init; }
 }

an item of the generated JS will look like this:
{ 'Id': 4, 'Name': 'Joe', 'Budget': , 'StartDate': new Date(2023, 2, 20, 0, 0, 0, 0) }

This is invalid JS syntax, which causes the jqxgrid to not render

Replacing 'decimal' with 'double' resolve the issue
