Web forms - Manage users and roles (Identity 2.2.1 )

Chriz L

Hello,

I want to build an admin panel where the admin can create roles,users, assign users to roles and reset passwords. I'm using Identity 2.2.1 with web forms

I would appreciate any kind of help. Thank you in advance.

I' m having problem with the following two.

Resetting the password

I tried using the default ResetPassword.aspx in Account folder but I get the following error "An error has occurred" .

Create role and assign role at the same time:

I'm using the following code:

protected void btnAssignRole_Click1(object sender, EventArgs e)
{
RoleActions role = new RoleActions();
role.AddUserAndRole(roleTxt.Text, userTxt.Text, emailTxt.Text, passTxt.Text);
}

but I get the following error "An exception of type 'System.InvalidOperationException' occurred in mscorlib.dll but was not handled in user code. Additional information: UserId not found." in RoleActions.cs

internal void AddUserAndRole(String role, String user, String email, String pass)
{
Models.ApplicationDbContext context = new ApplicationDbContext();
IdentityResult IdRoleResult;
IdentityResult IdUserResult;
var roleStore = new RoleStore(context);
var roleMgr = new RoleManager(roleStore);
if (!roleMgr.RoleExists(role))
{
IdRoleResult = roleMgr.Create(new IdentityRole { Name = role });
}
var userMgr = new UserManager(new UserStore(context));
var appUser = new ApplicationUser
{
UserName = user,
Email = email
};
IdUserResult = userMgr.Create(appUser, pass);
if (!userMgr.IsInRole(user, role))
{
IdUserResult = userMgr.AddToRole(user, role);
}
}

No,I'm using web forms.

Are you using MVC,
If yes can use OWIN and role based authentication.

This is the code for resetting the password:
protectedvoidReset_Click(objectsender,EventArgse)
{
stringcode=IdentityHelper.GetCodeFromRequest(Request);
if(code!=null)
{
varmanager=Context.GetOwinContext().GetUserManager();
varuser=manager.FindByName(Username.Text);
if(user==null)
{
ErrorMessage.Text="Nouserfound";
return;
}
varresult=manager.ResetPassword(user.Id,code,Password.Text);
if(result.Succeeded)
{
Response.Redirect("~/Account/ResetPasswordConfirmation");
return;
}
ErrorMessage.Text=result.Errors.FirstOrDefault();
return;
}
ErrorMessage.Text="Anerrorhasoccurred";
}
I get null value on code but I can't figure out why.

"An error has occurred" is probably the top most error shown to you. Please keep looking into InnerException till such time as it is not null. The real error will be shown there. Then please share that error with us.
