Microsoft.AspNetCore.Mvc.Rendering

Assembly:

Microsoft.AspNetCore.Mvc.ViewFeatures.dll

Package:

Microsoft.AspNetCore.App.Ref v9.0.0

Returns an <input> element of type "radio" for the specified expression. Adds a "value" attribute to the element containing the first non-null value found in: the value parameter, or the htmlAttributes dictionary entry with key "value". Adds a "checked" attribute to the element if value matches the first non-null value found in: the htmlAttributes dictionary entry with key "checked", or the ModelState entry with full name. If expression evaluates to a non-null value, instead uses the first non-null value found in: the ModelState entry with full name, or the expression evaluated against Model. See NameFor<TResult>(Expression<Func<TModel,TResult>>) for more information about a "full name". Adds a "value" attribute to the element containing the value parameter.
