Membership Provider - Registration Form

Hi All, I am trying to create a registration form using the below code.

This works fine, however, I really want to be able to place my MemberProperties in specific places within my markup, rather than just iterating through them by index.

I have tried to use the code snippets found in this great article: https://24days.in/umbraco-cms/2015/membership-apis-investigation/

But can't seem to get anywhere without a YSOD

Any help would be greatly appreciated,

Tris

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using System.Web.Mvc.Html
@using ClientDependency.Core.Mvc
@using Umbraco.Web
@using Umbraco.Web.Controllers

@{

    var registerModel = Members.CreateRegistrationModel();

    Html.EnableClientValidation();
    Html.EnableUnobtrusiveJavaScript();
    Html.RequiresJs("/umbraco_client/ui/jquery.js");
    Html.RequiresJs("/umbraco_client/Application/JQuery/jquery.validate.min.js");
    Html.RequiresJs("/umbraco_client/Application/JQuery/jquery.validate.unobtrusive.min.js");

    var success = TempData["FormSuccess"] != null;
}

@if (success) 
{ 
    <p>Registration succeeeded.</p>
}
else
{
    using (Html.BeginUmbracoForm<UmbRegisterController>("HandleRegisterMember"))
    {
        <fieldset>
            <legend>Register Member</legend>

            @Html.ValidationSummary("registerModel", true)

            @Html.LabelFor(m => registerModel.Name)
            @Html.TextBoxFor(m => registerModel.Name)
            @Html.ValidationMessageFor(m => registerModel.Name)
            <br />

            @Html.LabelFor(m => registerModel.Email)
            @Html.TextBoxFor(m => registerModel.Email)
            @Html.ValidationMessageFor(m => registerModel.Email)
            <br />

            @Html.LabelFor(m => registerModel.Password)
            @Html.PasswordFor(m => registerModel.Password)
            @Html.ValidationMessageFor(m => registerModel.Password)
            <br />

            @if (registerModel.MemberProperties != null)
            {
                for (var i = 0; i < registerModel.MemberProperties.Count; i++)
                {
                    @Html.LabelFor(m => registerModel.MemberProperties[i].Value, registerModel.MemberProperties[i].Name)
                    @Html.EditorFor(m => registerModel.MemberProperties[i].Value)
                    @Html.HiddenFor(m => registerModel.MemberProperties[i].Alias)
                    <br />
                }
            }

            @Html.HiddenFor(m => registerModel.MemberTypeAlias)
            @Html.HiddenFor(m => registerModel.RedirectUrl)
            @Html.HiddenFor(m => registerModel.UsernameIsEmail)

            <button>Register</button>
        </fieldset>
    }

Hi Tris,

Can you post the contents of the YSOD? This might give us a clue as to what is going wrong.
