RadioButtonFor with boolean

Hi,

Using standard MVC libraries I can use:

@Html.RadioButtonFor(m => m.IsActive, "true")
@Html.RadioButtonFor(m => m.IsActive, "false")

where:

IsActive is a bool

To create a radio button that toggles IsActive between true and false.

However when I try to do this with EJ

@Html.EJ().RadioButtonFor(m => m.IsActive, "true")
@Html.EJ().RadioButtonFor(m => m.IsActive, "false")

I get the exception:

Cannot convert System.Boolean to System.String.

I have also tried:

@Html.EJ().RadioButtonFor(m => m.IsActive, true)
@Html.EJ().RadioButtonFor(m => m.IsActive, false)

But I get the same result

I cannot find the correct usage of this control in your documentation, so I am wondering how to correctly create a control like this.

Thanks

Hi Campbell, 
 
Thanks for using Syncfusion controls. 
 
We have checked your query in Radio Button control. we suspect that you have defined IsActive datatype as Boolean in models file. EJ Radio button value was string type so that issue was arises in your case. To resolve your problem, please change the IsActive datatype as string. Please refer to the below code block. 
 
[HomeController.cs] 
 
    
RadioModel model = new RadioModel(); 
   public ActionResult Index() 
        { 
            model.IsActive = "true"; 
            return View(model); 
        } 
 
 
 
  public class RadioModel 
    { 
        public string IsActive { get; set; } 
    } 
 
 
[Index.cshtml] 
 
    @Html.EJ().RadioButtonFor(m => m.IsActive, "true") 
    <label for="Radio1" class="clslab">True</label> 
 
    @Html.EJ().RadioButtonFor(m => m.IsActive, "false") 
    <label for="Radio2" class="clslab">False</label> 
 
 
We have prepared sample for your convenience, please refer to the below link for the sample. 
 
 
 
Please let us know, if you need any assistance.

Thanks Muthukrishnan,

So by your example there is no way to do this with a Boolean instead of a string?

If so then I will just use the standard EJ radiobutton and parse it myself, as the datatype of IsActive needs to remain as a bool.

Is there a way to submit a change request to get this functionality added? It is already possible using standard MVC controls so it would make sense to have it in EJ too

Hi, 
Could you confirm the update only for EJ version? How about EJ2, because I'm still facing the issue in EJ2 with version 18.1.0.42.
