thanks,

here's recommend you. start clean view model, 1 expresses view contains information:

public class employeesviewmodel { public list<employeeviewmodel> listemployee { get; set; } [required] public int? selectedemployeeid { get; set; } } public class employeeviewmodel { public int id { get; set; } public string label { get; set; } }

then controller:

public class homecontroller : controller { public actionresult index() { var model = new employeesviewmodel { listemployee = getemployees() }; homecoming view(model); } [httppost] public actionresult index(employeesviewmodel model) { if (!modelstate.isvalid) { // model invalid, user didn't select employee // => refetch employee list repository , // redisplay view can prepare errors model.listemployee = getemployees(); homecoming view(model); } // validation passed @ stage // todo: model.selectedemployeeid contain id // of selected employee => utilize repository fetch // actual employee object , // (like grant him employee of month prize :-)) homecoming content("thanks submitting", "text/plain"); } // todo: doesn't belong here // it's demonstration purposes. in real // application have repository, utilize di, ... private list<employeeviewmodel> getemployees() { homecoming new[] { new employeeviewmodel { id = 1, label = "john (hr)" }, new employeeviewmodel { id = 2, label = "peter (it)" }, new employeeviewmodel { id = 3, label = "nathalie (sales)" }, }.tolist(); } }

and view:

@model employeesviewmodel @using (html.beginform()) { @html.validationmessagefor(x => x.selectedemployeeid) @foreach (var employee in model.listemployee) { <div> @html.radiobuttonfor(x => x.selectedemployeeid, employee.id, new { id = "emp" + employee.id }) @html.label("emp" + employee.id, employee.label) </div> } <input type="submit" value="ok" /> }
