public class registerviewmodel { [required] [displayname("user name")] public string username { get; set; } [required] [remote("emailalreadyexists", "validation", errormessage = "user mail exists")] [displayname("email")] public string email { get; set; } [required] [displayname("password")] public string password { get; set; } [required] [datatype(datatype.password)] [displayname("confirm password")] public string confirmpassword { get; set; } [required] public ienumerable<selectlistitem> roles { get; set; } } my role model
public class role { public int id { get; set; } public string name { get; set; } } view roles is,
<div class="form-group"> @html.labelfor(model => model.roles, htmlattributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @html.dropdownlistfor(model => model.roles, model.roles, "select roles" , new {id = "roles" }) @html.validationmessagefor(model => model.roles, "", new { @class = "text-danger" }) </div> </div> and controller
public actionresult index() { registerviewmodel uvm = new registerviewmodel(); uvm.roles = r in roles select new system.web.mvc.selectlistitem { text = r.name, value = r.id.tostring() }; return view(uvm); } [httppost] [validateantiforgerytoken] public actionresult index(registerviewmodel register) { if (modelstate.isvalid) { string code = guid.newguid().tostring(); userrepo.insert(new models.user() { username = register.username, email = register.email, password = register.password, /* role = register.roles */ createddate = datetime.now, authcode = code, status = false }); sendmail(register.username, register.email, code); return redirecttoaction("thankyou"); } return view(register); }
add new property in registerviewmodel
public class registerviewmodel { [required] [displayname("user name")] public string username { get; set; } [required] [remote("emailalreadyexists", "validation", errormessage = "user mail exists")] [displayname("email")] public string email { get; set; } [required] [displayname("password")] public string password { get; set; } [required] [datatype(datatype.password)] [displayname("confirm password")] public string confirmpassword { get; set; } [required] public ienumerable<selectlistitem> roles { get; set; } **public string selectedrole {get;set;}** } and dropdown sould bewlo
@html.dropdownlistfor(model => model.selectedrole , model.roles, "select roles" , new {id = "roles" }) you controller action like
[httppost] [validateantiforgerytoken] public actionresult index(registerviewmodel register) { if (modelstate.isvalid) { string code = guid.newguid().tostring(); userrepo.insert(new models.user() { username = register.username, email = register.email, password = register.password, role = register.selectedrole createddate = datetime.now, authcode = code, status = false }); sendmail(register.username, register.email, code); return redirecttoaction("thankyou"); } return view(register); }
