Question

I’m trying to make a sign in page for Sharepoint 2010 using Forms Based Authentication.
I followed a tutorial and ended up with my project showing the above error (object not set to instance of an object).

[NullReferenceException: Object reference not set to an instance of an object.]
Microsoft.SharePoint.IdentityModel.Pages.FormsSignInPage.OnLoad(EventArgs e) +119
NDELogin.Layouts.NDELogin.Login.OnLoad(EventArgs e) +51
System.Web.UI.Control.LoadRecursive() +65
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2427

Would someone take a look at the Code/Aspx and tell me if you see anything wrong.

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using Microsoft.SharePoint.IdentityModel.Pages;

namespace NDELogin.Layouts.NDELoginc
{
public partial class Login : FormsSignInPage
  {
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
    }
  }
}

I just answered my own question… set MembershipProvider=”FBAMembershipProvider” on the login control
