MVC :: EF Design / "Entities In 'EntityContainer.ProductTypes' Error

Mar 23, 2011

I have two entities: Product and ProductType. I've generated a controller and views for both and can manage ProductTypes, however, when attempting to create a new Product, I get the error below:

"Entities in 'EntityContainer.ProductTypes' participate in the 'ProductProductType' relationship. 0 related 'Product' were found. 1 'Product' is expected."

the reason being that my view, as automatically generated, doesn't know about ProductType. how is this generally handled? I would like to display a listbox of product types on the product form and insert the right value.

ADO.NET :: EF4 Entities / Create Entities, For Instance, That Only Contains Contact Details Of Client Table?

Nov 16, 2010

I have a datamodel with a couple of tables. One of my tables have about 40 fields (I know that is a lot, but we have to keep the structure in place as we are upgrading a classic ASP project to MVC). Some of my Actions only updates 1 or 2 fields in my table.

Is there a way to create Entities, for instance, that only contains the contact details of the client table, and not any other details, and then another entity that contains only the address details. I don't want to submit the entire row when I only update telephone details, or the client's picture.

Self Tracking Entities Vs POCO Entities

Sep 28, 2010

We are starting a new web based product in which we are planning to expose our business logic through WCF services. We will be using ASP.NET 4.0, C#, EF 4.0. In future we want to build iphone applications and WPF applications based on the services. I have been reading a lot about using POCO vs Self Tracking Entities (STE) and from my understand the STEs do not work well with the web scenario.

AJAX :: TabControl Inside FormView Throws Error In Design Time

Dec 9, 2010

I'm trying to use a Tab control with 5 tabs inside a form view, when I view my aspx page in Visual Studio 2008 it displays a error message stating "There was an error rendering the control. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "" was coreectly embedded or linked into assembly ... " running the site just shows a blank page (as the control isn't rendered).

If I remove the tab control from within the ItemTemplate (or EditItemTemplate) and put it directly onto the page it works fine. Googling for the error suggests the references aren't correct, so I've reset the toolbox, and re-added the reference - this time referencing the file in my Bin folder (not the installation path of the Ajax Toolkit). Still it throws the same error. Finally I've stripped the code out into a page with the bare minimum (no code behind) and it still throws the same error. I'm sure I had this working previously. I'm using Visual Studio 2008 on Windows 7 and I'm using the 3.5 files from Codeplex ( targetting .NET Framework 3.5.

Custom Server Controls :: Custom Control Design View Error

Aug 13, 2010

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:


I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it does.

C# - Software Design & Web Service Design

Dec 30, 2010

I'm about to design my Web service API, most of the functions of my API is basically very simular to my web application. Now the question is, should I create 1 single method and reuse them for both the web application and the web service api? (This seems to be the logical solution, however its very complicated; it's much easier to duplicate the method used by the web application, and keep both separate, ie one method for the web application and one method for the web service.)

1) REUSE: one main method and reuse them for both web application and web service application (I like this but it's complicated)

WebAppMethodX --uses-->
APIMethodX ---uses---->
ie Commonfunctionmethod_x contains reusable set of common features
PRO: less code, less maintenance, less bugs.
CON: very complicated

2) DUPLICATE: two methods, one method for the web application and one method for the web service.

PRO: simple
CON: duplication = more code, more maintenance, more bugs!

C# - Web Service Design - Error Code (store In Source Code Or Store In Database?

Jan 19, 2011

Web service error response (code/message etc) would you store it in a database? or would you keep the error response in a method.By the time I'm done with this, there will be hundreds of error response, maybe in the future, thousands? (I dont know yet, depends how large this web service grows).EDIT: error response is the response returned back to the application via the web service, (not to be confused with error logging).
