I'm having this very annoying issue.Trying to make ASP.NET profile work in my MVC2 application.This is the C# code:
[Code]....
Here is the web.config file:
[Code]....
And finally the controller action:
[Code]....
As soon as I submit the form I get an error. I can't even debug C# as the error occurs before stepping into
public ActionResult Create(UserProfile model, string submitButton)...The error is:
Server Error in '/' Application.

I'm trying to add two features to my website using the microsoft built-in login features. One feature I want to change is the validation of the username. By default, it allows pretty much any characters for the username. However, I want to make it so that only alphanumeric characters, and spaces. Also, I want to make it so that usernames MUST begin with a letter. I'm not entirely sure how to do this, In addition, I want to configure it so that once an account is created, a file /users/(their username)/(their username).aspx created once they are authenticated, with the master page set to userProfileMaster.master

I'm using profiles to save control settings of users.
I have a check box that enables them to 'enable' saving their settings.
rather than cycling through each parameter, and setting them to Null,
is there a way I can do something like:
Profile.Something = Null

This is really weird - I've got a MVC app running, including a Login method in my ServicesController class:
public ActionResult Login() {
var p = Request.Params;
var userName = p["username"];
var password = p["password"];
// etc...
}

I have a standard Login form
<asp:Login ID="lgnExcel" DestinationPageUrl="login/data.aspx" OnAuthenticate="Login1_Authenticate" runat="server">
Is it possible to attach the Username as a query string with the DestinationPageUrl or reference the value in the code behind. I've tried lgnExcel.UserName.ToString()

I have a Stored Proc which uses a field in the database. that ends up being the user.identity.name. So, when the page loads, it grabs that name and uses it in the stored proc, which I'm which I'm wanting to designate in the sql datasource. But it only gives me choices of querystring, cookie, session, control, etc. My question is how to reference that variable as the parameter in the datasource?

I have an ASP.NET VB website in which I am using the Membership functionality to authenticate users. I am doing this through the Login control on the HTML page. I have working that it will authenticate the user and then opens a welcome screen in which I have a button they can push to open a Reports.aspx page. On that page I have a dropdown box that is being populated from a datasource connection query to my SQL Server database table. It is a hard coded query but want it to query the table off the username text value that the user provided on the login (i.e. select <something> from inventory where username = <username>). I have not behind code but only HTML at this point. Here it is ...
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="Login" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Here is the Reports form that has the dropdown on it:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Report.aspx.vb" Inherits="Report" %>

I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

i am inserting the value of dynamic controls into the db like so;
Dim ae1 As DropDownList = FindControl("AreasExpertise1")
If (ae1 IsNot Nothing) Then
x.Parameters.AddWithValue("@areasexpertise1", ae1.SelectedValue)
End If
then in my query i have parameters like so;
INSERT INTO [foo] ([etc], [etc], [etc], [areasexpertise1], [areasexpertise2])
VALUES (@etc, @etc, @etc, @areasexpertise1, @areasexpertise2)
When the user fills out the form, they see only areasexpertise1 and have to press a button to dynamically insert another area of expertise...If they only have 1 area of expertise, the query crashes and says 'must declare variable @areasexpertise2.Please can you tell me a way to either insert nulls when the parameters are empty, or to ignore them?

I'm using a custom route to create the following URL (http://mysite/subscriber/12345) where 12345 is the subscriber number. I want it to run the ShowAll action in the Subscriber controller. My route is firing and using Phil's route debugger, when I pass in the above url, the route debugger shows ID as 12345.
My controller is accepting an int as subscriberID. When it fires, the controller throws the error "The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32". Why does the route debugger show a value and the controller doesn't see it?
Here's my route (first one is the culprit)
routes.MapRoute(
"SubscriberAll",
"subscriber/{id}",
new { controller = "Subscriber", action = "ShowAll", id=0 },
new { id = @"d+" } //confirm numeric
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I'm getting a null in the ShowAll action? Here is the action method signature:
public ActionResult ShowAll(int id)
