- create a span before first LI as label
- UL shall reference span via aria-labelledby
- group label needs to look like a group label (it must be more significant/important than the radio labels)
As these elements are wrapped by the control this needs to be updated internally.
There is an attribute called AriaLabelledBy available on the control but it does not work. It would be good for the AriaLabelledBy attribute to do what it is supposed to do and make it work like the following code:
<h3 id="grouplabel1">Chosen gender: @( ChosenGender == 0 ? "no selection yet" : ChosenGender.ToString() )</h3>
<TelerikRadioGroup Data="@GenderOptions"
@bind-Value="@ChosenGender"
ValueField="@nameof(GenderModel.GenderId)"
TextField="@nameof(GenderModel.GenderText)" AriaLabelledBy="grouplabel1">
</TelerikRadioGroup>
@code {
TelerikRadioGroup<GenderModel, int?> RadioGroupRef { get; set; }
int ChosenGender { get; set; }
List<GenderModel> GenderOptions { get; set; } = new List<GenderModel>
{
new GenderModel { GenderId = 1, GenderText = "Female" },
new GenderModel { GenderId = 2, GenderText = "Male" },
new GenderModel { GenderId = 3, GenderText = "Other" },
new GenderModel { GenderId = 4, GenderText = "Prefer not to say" },
};
public class GenderModel
{
public int GenderId { get; set; }
public string GenderText { get; set; }
}
}----------ADMIN EDIT----------
A possible workaround is to wrap the RadioGroup inside a normal div and use the normal HTML aria-labelledby attribute:
<div role="radiogroup" aria-labelledby="group_label_1">
<h3 id="group_label_1" >Chosen gender: @( ChosenGender == 0 ? "no selection yet" : ChosenGender.ToString() )</h3>
<br />
<TelerikRadioGroup Data="@GenderOptions"
@bind-Value="@ChosenGender"
ValueField="@nameof(GenderModel.GenderId)"
TextField="@nameof(GenderModel.GenderText)">
</TelerikRadioGroup>
</div>
@code{
TelerikRadioGroup<GenderModel, int?> RadioGroupRef { get; set; }
int ChosenGender { get; set; }
List<GenderModel> GenderOptions { get; set; } = new List<GenderModel>
{
new GenderModel { GenderId = 1, GenderText = "Female" },
new GenderModel { GenderId = 2, GenderText = "Male" },
new GenderModel { GenderId = 3, GenderText = "Other" },
new GenderModel { GenderId = 4, GenderText = "Prefer not to say" },
};
public class GenderModel
{
public int GenderId { get; set; }
public string GenderText { get; set; }
}
}
A RadioGroup inside a Grid EditorTemplate will fire OnBlur when the user clicks on it. This will close the edit cell and (usually) not apply the new value.

When I test the accessibility of the TelerikRadioGroup I have found out issues.
