You have written like   Html RadioButtonFor model   gt  model gender   Male   new    checked   true    and  Html RadioButtonFor model   gt  model gender   Female   new    checked   true      Here you have taken gender as a Enum type and you have written the value for the radio button as a string type- change  Male  to 0 and  Female  to 1

Here is how I do it and works both for create and edit     How to do it with enums  lt div class  editor-field  gt      Html RadioButtonFor x   gt  x gender   int Gender Male  Male     Html RadioButtonFor x   gt  x gender   int Gender Female  Female  lt  div gt     And with Booleans  lt div class  editor-field  gt      Html RadioButtonFor x   gt  x IsMale  true  Male     Html RadioButtonFor x   gt  x IsMale  false  Female  lt  div gt    the provided values  true and false  are the values that the engine will render as the values for the html  element  i e     lt input id  IsMale  type  radio  name  IsMale  value  True  gt   lt input id  IsMale  type  radio  name  IsMale  value  False  gt    And the checked property is dependent on the Model IsMale value   Razor engine seems to internally match the set radio button value to your model value  if a proper from and to string convert exists for it  So there is no need to add it as an html attribute in the helper method

Don t do this at the view level  Just set the default value to the property in your view model s constructor  Clean and simple  In your post-backs  your selected value will automatically populate the correct selection   For example  public class MyViewModel           public MyViewModel                         Gender    Male                  x000D   x000D   lt table gt  x000D     lt tr gt  x000D    lt td gt  lt label gt  Html RadioButtonFor i   gt  i Gender   Male  Male lt  label gt  lt  td gt  x000D    lt td gt  lt label gt  Html RadioButtonFor i   gt  i Gender   Female  Female lt  label gt  lt  td gt  x000D     lt  tr gt  x000D    lt  table gt  x000D   x000D   x000D

Add checked to both of your radio button  And then show hide your desired one on document ready   lt div class  quot form-group quot  gt       lt div class  quot mt-radio-inline quot  style  quot padding-left 15px  quot  gt           lt label class  quot mt-radio mt-radio-outline quot  gt              Full Edition              lt input type  quot radio quot  value  quot    int SelectEditionTypeEnum FullEdition  quot  asp-for  quot SelectEditionType quot  checked gt               lt span gt  lt  span gt           lt  label gt           lt label class  quot mt-radio mt-radio-outline quot  gt              Select Modules              lt input type  quot radio quot  value  quot    int SelectEditionTypeEnum CustomEdition  quot  asp-for  quot SelectEditionType quot  checked gt               lt span gt  lt  span gt           lt  label gt       lt  div gt   lt  div gt
