Programmatically Created Form - Nested Forms Example

[janamargaret]

Hello! Do you have any code examples of how to get either of the Nested Forms examples on http://formfactoryaspmvc.azurewebsites.net/) working for a Programmatically Created Form?

No... I think you can maybe use an object as the outer item:

    new PropertyVm(typeof(object), "outer") //<!- 
     {
         DisplayName = ...,
         Value = ... inner PropertyVm[] ,
         ...
    {
}

Thanks for the great work. Sorry if I am doing something obviously wrong, I've just started playing with FromFactory. I am trying to do this as well, but when I put a PropertyVm array in for the Value of the object, I am System.StackOverflowException. Any ideas what I am missing?

Thanks

Can you send me a code snippet please?

Of course. Right now I am just playing around with the example code. Please see below:

       var lasers = new[] {
             new PropertyVm(typeof(string) , "Left")
                {
                    DisplayName = "Left",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
              new PropertyVm(typeof(string) , "Right")
                {
                    DisplayName = "Right",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
               new PropertyVm(typeof(string) , "Ceiling")
                {
                    DisplayName = "Ceiling",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
                new PropertyVm(typeof(string) , "Sagital")
                {
                    DisplayName = "Sagital",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
        };

        var formModel = new[]
       {
                new PropertyVm(typeof(object) , "outer")
                {
                    DisplayName = "Laser Alignment",
                    NotOptional =true,
                    Value=lasers
                },

          };

Ah I can see the problem. PropertyVms aren't designed to be nested, instead they should be rendered as a flat list.

If you want to do what you are after, try putting the parent item name into each PropertyVms name e.g. for Left, use outer.Left :

var lasers = new[] {
             new PropertyVm(typeof(string) , "outer.Left")
                {
                    DisplayName = "Left",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
              new PropertyVm(typeof(string) , "outer.Right")
                {
                    DisplayName = "Right",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
               new PropertyVm(typeof(string) , "outer.Ceiling")
                {
                    DisplayName = "Ceiling",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
                new PropertyVm(typeof(string) , "outer.Sagital")
                {
                    DisplayName = "Sagital",
                    NotOptional =true,
                    GetCustomAttributes = () => new object[] { new DataTypeAttribute("TitleTol") }
                },
        };
