Determine If A Profile Data Member Has Ever Been Set?
Jul 8, 2010
I have a profile variable, and when I load it then it is assigned default values. I need to check to see if it has ever been assigned. Typically I'd use an is null comparison but that won't work.
It was suggested I use the FindProfilesByUserName which seems backward. Regardless this method wont work as it only tells me if the user has any profile created but not for the specific member data I'm interested in. (It seems backwards because the whole purpose of the profiles was to make it easy to access the current user profile data. This seems like a bad design unless I'm missing something.)
The last option I can see is assigning bits to every object to see if they were dirtied or set. I don't want to do this unless required though.
Here is the FindProfilesByUserName sample :
ProfileInfoCollection profileInfo = ProfileManager.FindProfilesByUserName(ProfileAuthenticationOption.All, Membership.GetUser().UserName);
if (profileInfo.Count > 0)
{
if (profileInfo[Membership.GetUser().UserName] != null)

I have been struggling to save custom property data into member using createuserwizard. I add some extra fields into createuserwizard using wizardsteps and What I would like to accomplish is to save extra data of that fields and see that data on admin backend of member section of umbraco cms.
What I have done so far in brief:
Created a user control using asp.net createuserwizard and save it to umbraco.
I also added a macro into usercontrol which pulls its data from dropdown list multiple render control data type which has some prevalues.
After selecting values and creating user, none of the selected values of dropdown list multiple render control data type are selected on admin backend but address are successfully saved.
Code behind file:Roles.AddUserToRole(UserName.Text, "BasicUsers");var profile = System.Web.Profile.ProfileBase.Create(UserName.Text);profile["sector"] = Sector.SelectedItem.Value;profile["address"] = Address.Text;profile.Save();
That relevant code snippet above works well like profile["address"] = Address.Text; but I am unable to save with other renders controls as Dropdown list multiple.

I am new to asp.net's membership controls. I am trying to figure out how to make a public profile page that will display information about a site member to other users. I thought I would be able to use the profile class and just pass in a parameter such as user name. But I tried:
Profile.GetProfile("username")
'Where username = name of profile I want to retrieve
Response.Write(Profile.Title)
Response.Write(Profile.Company)
However, if the user is logged in this codee just brings back their details, not those of the username requested. What am I doing wrong?

I was just wondering if anyone has ever had to port the schema across? Are there any experts that could pitch their opinions on the achievability of this (mad) idea? I'm using the IBM Migration Toolkit and as expected its throwing a bunch of translation errors some of which were relatively easy to solve (vendor specific function calls for example) and some will take quite a while to pin down and work round.... however this is not my main concern.
If completed I expect I am going to have to basically rework all the System.Web.Profile/Roles/Membership namespace classes etc to work round the SQL limitations of informix (i.e. IDS11.x SQL server doesnt have a DEFAULT (newguid()) so that would have to be put into the calling method) (and any MVP comments really as I can slap my boss round with the weight after he ludicrously agreed to this project for a client without doing any research...)

I have two member roles at my project:
1.) Administrator
2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?

I have following model class:
public class WebModel
{
public List<ArticleModel> Articles { get; set; }
}
public class ArticleModel
{
public int ID { get; set; }
public double ValueParam { get; set; }
}
Then I have the controller with the two actions:
[Authorize]
public ActionResult Index()
{
WebModel model = new WebModel();
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
[Authorize]
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(WebModel model, string saveButton)
{
ModelValidation.ValidateWebModel(model, ModelState);
if (ModelState.IsValid)
{
return RedirectToAction("Create", "Article");
}
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
And this is my view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Web.Models.WebModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<%var controller = Session["controller"] as Web.Code.SessionController; %>
<%Html.BeginForm(); %>
<div>
<table width="100%">
<%foreach (var article in Model.Articles)
{%>
<tr style="text-align: right">
<td>
<%:Html.DropDownListFor(m=>m.Articles.FirstOrDefault(f=>f.ID == article.ID).ID, new SelectList(controller.CurrentProdukt.Articles.AsEnumerable(), "ID", "Name", article.ID)) %>
</td>
<td>
<%:Html.TextBoxFor(m => m.Articles.FirstOrDefault(f => f.ID == article.ID).ValueParam)%>
</td>
</tr>
<%} %>
</table>
</div>
<table style="width: 100%">
<tr>
<td>
<input type="submit" name="saveButton" value="Save" />
</td>
</tr>
</table>
<%Html.EndForm(); %>
</asp:Content>
If I press the submit button, I get to the second action method in the controller (the one with the HttpPost attribute). In this action, the object model itself is not null, but the "Articles" list inside is null.

I am using profile services to store some attributes of users registered in the website. Now I am making a display profile page for a user. The problem is that the profile loads easily when I am running the site from VS 2010, but it gives the following error when I run it from IIS7 on my local machine:
System.NullReferenceException: Object reference not set to an instance of an object.

I'm trying to create a member section for my website and a non member section. I want the nonmember pages to have access to all the member pages but just not certain features like saving to the database. Is there a way to have the same page for both members and non members but have certain controls like buttons and other things that are only usable to the member that is logged in?

I'm being stupid but don't know what I'm missing.I want to use asp.net profile and have a profile property.So in the webconfig for my site I've added:
<profile>
<properties>
<add name="Name"/>
</properties>
</profile>
But in the code behind a page I cannot use Profile.Visual Studio is just saying the Profile is not known in the current context.Thus I cannot do
Profile.Name = ....
or
x = Profile.GetPropertyValue(....)

is there something special with other data type beside string in the data contract? I have two properties with decimal and datatime datatype. Everytime I change the value (either in client side and server side), the changed value will not be reflected in the other end (say if the client changes the value then the service will not see the changes). However, everything works ok for string datatype.

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"
I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:
No default member found for type 'DBNull'. I am using the code below.
What object types are stored within DataKeys (I thought it was just integers or strings)
How to handle a NULL datakey value to prevent this error occurring?

I am creating a WebApp and got stuck on the "Save" process. I am gathering data from a SQL DB and using a DataReader to populate the DataList. The DataList hold employee data and there are quite a few. What is the best way to save the data to the database?
I had originally thought that once a Supervisor has verified the employee data, just click the "Update" button and save to the DB but how would I determine which fields in the DataList have been changed? I only want the changes saved.
use a Dataset to populate the DataList then build a second Dataset with the same structure and compare the two. Then save the changes to the DB. I had read before on the 4GuysFromRolla website that using Datasets in a web app wasn't the greatest ...
