C# - Find LoginView Control within MultiView

How to access LoginView1 control inside Multiview1, View2?
I have a some textbox and dropdownlist in loggedIn template of View 2 within Multiview, I need to get the control and bind with text from database.
I had try:
((TextBox)this.LoginView1.FindControl("custEmail")).Text = dr.GetValue(1).ToString();
((TextBox)LoginView1.FindControl("custEmail")).Text = dr.GetValue(1).ToString();
((TextBox)LoginView1.FindControl("custEmail")).Text = "xxxx";
return "Object reference not set to an instance of an object."

Keep in mind that FindControl searches only the current level If you want to search in the branches (inside a MultiView, Panel, PlaceHolder, etc.) as well then you have to use some kind of recursive search.
First find the control in multiview control and by using MultiView.FindControl Method and then access the child controls in that found control

Object reference not set to an instance of an object errors when using CreateUserWizard
The error - "Object reference not set to an instance of an object" occured when I hit the "Next' button of my CreateUserWizard controls. I had checked through my codes that I did not leave any of my variables null. but i still can't solve this errors.
This is the caused of the error:

Source Error:
Line 29: object UserGUID = User.ProviderUserKey;

This is the code behind:
using System;
using System.Data;
using System.Configuration;
using System.Web.Security;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Register : System.Web.UI.Page

TextBox UserName=
(TextBox)CreateUserWizardStep2.ContentTemplateContainer.FindControl("UserName");
SqlDataSource DataSource =
(SqlDataSource)CreateUserWizardStep2.ContentTemplateContainer.FindControl("InsertExtraInfo");
MembershipUser User = Membership.GetUser(UserName.Text);
object UserGUID = User.ProviderUserKey;
DataSource.InsertParameters.Add("UserId", UserGUID.ToString()); //the error lies at here
DataSource.Insert();
}
}

The InsertExtraInfo is actually inside CompleteWizardStep1. Try this:
SqlDataSource DataSource =
(SqlDataSource)CompleteWizardSetp1.ContentTemplateContainer
.FindControl("InsertExtraInfo");
But I believe you can use the outermost container CreateUserWizard1 so you don't have to worry about which step it's in.
CreateUserWizard1.FindControl("InsertExtraInfo");

you dont need to place SqlDataSource control inside wizardcontrol. move it out. and you dont need to find it. just access it by its ID.

MembershipUser User = Membership.GetUser(UserName.Text);
object UserGUID = User.ProviderUserKey;
DataSource.InsertParameters.Add("UserId", UserGUID.ToString()); //the error lies at here
DataSource.Insert();
}
}

I had checked through my codes that I did not leave any of my
variables null. but i still can't solve this errors.
You have not checked all your variables, otherwise this error would not be occurring.
Have you checked your DataSource to ensure the SqlDataSource is being found? The InsertParameters property of the DataSource to ensure that it is not null? The UserGUID to ensure that it is not null?

Adding Regex Validators with CreateUserWizard they are not Working

I am adding some regex with the register user steps, they are working because the '*' is being displayed but the Wizard will still let me create an account with errors of regex.
I tried to redo the wizard
Changing some features but nothing

Assuming your Create Use wizard looks like this
<asp:CreateUserWizard ID="CreateUserWizard1" runat="server" OnCreatedUser="CreateUserWizard1_CreatedUser"
DisableCreatedUser="true" EmailRegularExpression="^((?:(?:(?:\w[\.\-\+]?)*)\w)+)\#((?:(?:(?:\w[\.\-\+]?){0,62})\w)+)\.(\w{2,4})$"
Font-Size="Small">
<CreateUserButtonStyle CssClass="button" />
<ErrorMessageStyle Font-Size="Small" />
<TextBoxStyle CssClass="textbox txtsingleline" />
<ValidatorTextStyle Font-Size="Small" />
<WizardSteps>
<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
</asp:CreateUserWizardStep>
<asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server">
</asp:CompleteWizardStep>
</WizardSteps>
</asp:CreateUserWizard>
You can access the validators as follows:
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("UserNameRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("PasswordRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("ConfirmPasswordRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("EmailRequired")
(CompareValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("PasswordCompare")
(RegularExpressionValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("EmailRegExp")
Hope this helps
Thank You :)

Use the correct ID for ValidationGroup.
Should be "RegisterUser" instead of "CreateUserWizard1"

and the code behind :
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void redirect(object sender, EventArgs e)
{
FormsAuthentication.SetAuthCookie(USER_NAME, true);
Response.Redirect("copyPastPage.aspx");
}
}
thanks in advance

FormsAuthentication.RedirectFromLoginPage(mainSignUp.UserName, true);
Put the above line inside the redirect method and remove those two lines and let us know if that helps

After a successfull Signup, just use this line:
FormsAuthentication.SetAuthCookie(USER_NAME, true);
the true at the end means (from official documentation):
true to create a persistent cookie (one that is saved across browser sessions); otherwise, false.

If you are using CreateUserWizard control for user registration, you may set a property LoginCreatedUser to true to automatically login a user after registration is complete.
