DataSource Controls :: The Null Value Cannot Be Assigned To A Member With Type System.Decimal Which Is A Non-nullable Value Type

Dec 22, 2010

I am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."

I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.

Dim invoices = From i In db.invoices _
Group Join p In db.products On i.id Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}

i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.

Namespace Or Type Specified Doesn't Contain Public Member

Feb 15, 2010

I have created a ASP.NET 3.5 web application and in it I have SearchGridView.vb class file in the directory Old_App_Code. This file creates a namespace MyApp.WebControls, which is also referenced in web.config in a namespace tag, as well as included as an import directive at the beginning of my content page. Unfortunately, I receive the following error: Warning 1 Namespace or type specified in the project-level Imports 'MyApp.WebControls' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. Here's the first several lines of my class file SearchGridView.vb:

why this is happening, as well as possible fixes? I cannot impement the asp:SearchGridView due to this error.

I created my own membership provider and membershipuser class. When i try go to the security tap in .net Configuration tool, i get following:

There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.

The following message may help in diagnosing the problem:

Security :: Custom Identity / SerializationException: Type Is Not Resolved For Member

Sep 10, 2009

In my ASP.NET mvc app, I wrote my own custom IIdentity which I swap with the default FORMS identity. I do this using Application_PostAuthenticateRequest in Global.asax. This works for the most part as it gives me a more meaningful identity prior to invoking actions on my MVC controller. Unforunately, things fall apart after the controller call. Something in the ASP.NET framework is bound and determined to serialize my identity and blows up during this process. I even made my custom identity serializable but it still blows up.
Note, I can serialize / deserialize this class in a unit test using the binary formatter.

Here is the exception:

[SerializationException: Type is not resolved for member 'MvcTest.Models.SiteUser,MvcTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.] Microsoft.VisualStudio.WebHost.Server.GetProcessToken() +0 Microsoft.VisualStudio.WebHost.Host.GetProcessToken() [code].....

Web Forms :: Getting Warning "Type Of Member Is Not CLS-compliant" On One ASPX Page Only

Apr 14, 2010

I have a working web app that uses a web service which is compiled into its separate assembly. I have another class library project compiled as a separate assembly that serves as a proxy to this web service. This all seems to work at runtime but I am getting this warning at compile time which I don't understand and would like to fix:

I have dozens of webforms in the main project that reference the proxy class with no compile time complaints as this snippet shows:

[Code]....

And yet I have one webform (also in the root of the main project) which gives me the "not CLS-compliant" message but yet attempts to reference the proxy class just like the other ASPX files. I get the compile time warning on the line annoted by me with 'ERROR here..

[Code]....

This makes no sense to me. The file with the warning is called frmHome.aspx.vb; all others in the project declare things the same way and have no warning. BTW, the webservice itself returns standard datatypes: integer, string, and dataset.

MVC :: Model With List As Member: Member Always Null After Submit?

Nov 25, 2010

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.

DataSource Controls :: Take Names From The Table And Do Another Select Based On That List Of Names?

Jun 1, 2010

I have been working with this database for some time. Here is the situation...

I inherited a MS SQL database that has hundreds of tables with similar data. For instance:

FordTampa_customer is a table,

ChevyAtlanta_customer is a table, etc....

All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...

So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.

All right, on to the real point of my post...

Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.

I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:

[Code]....

I am not sure how to take those names from the table and do another select based on that list of names.

Forms Data Controls :: Conversion From Type 'TextBox' To Type 'String' Is Not Valid?

Sep 6, 2010

I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.

2. I need to send an email confirmation of their registration to their email.

I know how to do both of these things, but i am having trouble doing both at the same time.

It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.

The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:

[Code]....

[Code]....

The Second page confirms the users information by taking those session variables and placing them into labels:

However, after I place information into the formview on the first page, it throws up this error:

"Conversion from type 'TextBox' to type 'String' is not valid".
