Examples of Radio Buttons with groups

Hi Ryan, I had a blog Creating a Radio Button Field describing how to create Radio Buttons in Rest and SDK methods. This is the .Net SDK code:

Field radio1 = FieldBuilder.RadioButton("group1")
                         .WithId(("signer1_group1_radio1")
                         .WithName(("signer1_group1_radio1")
                         .WithSize(15,15)
                         .OnPage(0)
                         .AtPosition(100,100)
                         .WithValue(true)                        //selected by default
                         .WithValidation(FieldValidatorBuilder.Basic().Required())  //add a required validator
               .Build();

And the equivalent JSON was:

{
   "id":"signer1_group1_radio1",
   "name":"signer1_group1_radio1",
   "type":"INPUT",
   "subtype":"RADIO",
   "page":0,
   "height":15,
   "width":15,
   "left":100,
   "top":100,
   "value":"X",
   "validation":{
      "required":true,
      "enum":[
         "group1"
      ]
   }
}

You can find more detailed explanations regarding the parameters in the article. Hope this could help! Duo

Duo, In the validation object, what is the enum field used for? Does it just need to contain the name of the group associated with the radio buttons?

Hi Ryan, Yes, exactly as you understood, the enum field is used to identify which group current field belongs to. To note, since fields are only bound to the specific signer so same as radio group, different signer with same group name won't cause ambiguity for OneSpan Sign. (although it's not suggested) Duo
