RadioGroup Does Not Pass Value To Post

[John]

I'm using the RadioGroup and setting the for to a string property in my page model.  The Get is working fine with displaying the value in the model but when I save the form, in the post the for value is null.  Any ideas on how to get this to work?

Razor Page

<kendo-radiogroup for="Input.OwnOrRentId"
    label-position="RadioGroupLabelPosition.Before"
    layout="RadioGroupLayout.Horizontal" bind-to="Model.OwnOrRentItems">
</kendo-radiogroup>

 

Code behind

 [BindProperty]
  public InstallerPageModel Input { get; set; }

 public List<IInputGroupItem> OwnOrRentItems { get; set; }

 

        OwnOrRentItems = new List<IInputGroupItem>()

        {

            new InputGroupItemModel()

            {

                Label = OwnOrRentOptions.Own.GetDescription(),

                Value = OwnOrRentOptions.Own.NumericValue().ToString(),

                Enabled = true,

                CssClass = "green",

                Encoded = false,

                HtmlAttributes = new Dictionary<string,object>() { { "data-custom", "custom" } }

            },

            new InputGroupItemModel()

            {

                Label = OwnOrRentOptions.Rent.GetDescription(),

                Value = OwnOrRentOptions.Rent.NumericValue().ToString(),

                Enabled = true,

                CssClass = "green",

                Encoded = false,

                HtmlAttributes = new Dictionary<string,object>() { { "data-custom", "custom" } }                   

            }

        };

 

   public class InputGroupItemModel :IInputGroupItem

   {

    public IDictionary<string, object> HtmlAttributes { get; set; }

 

    public string CssClass { get; set; }

 

    public bool? Enabled { get; set; }

 

    public bool? Encoded { get; set; }

 

    public string Label { get; set; }

 

    public string Value { get; set; }

   }

Hi John,

Thank you for bringing this issue to our attention.

For nested properties, the RadioGroup tag helper generates the name of its inputs with a lower dash (_), while it should generate those with a dot (.). Having that said, the value chosen is not properly passed to the page model. Here is a GitHub issue I have opened on the above:

https://github.com/telerik/kendo-ui-core/issues/6389

As a small token of gratitude for reporting the above, I have updated your Telerik points.

As a temporary workaround, you could manually set the input-name value of the Tag helper:

<kendo-radiogroup for="Input.OwnOrRentId"
				  label-position="RadioGroupLabelPosition.Before"
				  layout="RadioGroupLayout.Horizontal" bind-to="Model.OwnOrRentItems"
				  input-name="Input.OwnOrRentId">
</kendo-radiogroup>
