please me value mobile view. don't know have done wrong.

please take @ attachment pc , mobile view it's reason have define both html on 1 view.

desktop

mobile

thank much!

the main reason name of radio button on mobile view not correct , it's not matched , can not set defaultmodelbinder

@html.radiobuttonfor(m => model.selectedoption, 1, new { @name = "selectedoption_mb" }) 

i totally understand want value httpget method. data shown both mobile , desktop views.

in case, if want define both view different element on 1 view. should define more properties mobile view model. please refer code below:

model

public class testviewmodel {      public int? selectedoption { get; set; }      public int? selectedoption_mb { get; set; } } 

view

<table class="mb" style="border: 1px solid #eeecdc">  <tbody>   <tr>     <td> @html.radiobuttonfor(m => model.selectedoption_mb, 1)     </td>     <td> @html.radiobuttonfor(m => model.selectedoption_mb, 2)     </td>  </tr> 

controller

var value= model.selectedoption!=nul?            model.selectedoption:model.selectedoption_mb!=null?                                 model.selectedoption_mb:null;
