EF Custom Methods

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :ASP.Net

Hello all.  I am new to the Entity Framework (.NET 4.0) and I need some help and/or suggestions on how to accomplish something.  I am looking to create some methods with some of my data classes.  For the most part, they will do some validation and then update some fields in the database, or even update an associated table.  I have the basic setup for the EF model, but I cannot figure out how to get C# methods into the objects, as I would do when I was creating my own classes.

I have found that I can use a Stored Procedure and then import a function to get this to work but I would like to handle it in the code if I could.  I have also read about using POCO and partial classes but it does not seem to work the way I have seen it done in examples.  I cannot access the POCO Entity Code generator for some reason, and creating a partial class by hand ends up with it not being recognized.

So I am looking for a way to implement this or if I should be going about this a different way.  Most of the items I have read around the web seem to be lack

My custom class, Why method table only contain 4 methods?

I always get 4 methods information in method table.

The Decorator Pattern & Extension Methods

The decorator pattern provides a formal way to add new functionality to an existing type, without sub-classing. First question: What is wrong with classical inheritance? In and of itself, nothing is wrong with the good old Is-A relationship. It is very common to derive a new class from an existing base class in order to override a few virtual members, and add a pinch of new functionality.

Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

The Decorator Pattern & Extension Methods

Numerous design patterns exist in the software world today, and ultimately nothing is preventing you from making your own (if people buy into it or not is another question). Furthermore, there is no 'master list' of patterns that all developers agree upon. While this is true, if you pick up any book on the subject, you will find a set of very common patterns most programmers agree are very useful. Many of these patterns were first formalized in the seminal book on the subject, Design Patterns: Elements of Reusable Object-Oriented Software (aka, the Gang of Four [GOF] book; not to be confused with the UK punk band of the same name).

Write Custom WebParts for SharePoint 2007

The popularity of SharePoint Portal Server 2003 led Microsoft to tightly integrate the next SharePoint version, Microsoft Office SharePoint Server (MOSS) 2007, with its ASP.NET 2.0 WebPart framework. This tight integration enables the ASP.NET and SharePoint developer to do a number of things that previously weren't possible

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

Xml File Methods and Properties

Method and Properties of XmlTextWriter class:
The XmlWriter class is a base class that outputs an XML data structure. It has methods to sequentially write XML elements in a proper hierarchy to create an XML file or other types of output streams. The System.Xml namespace provides support for the XmlWriter. It must be imported to the ASP.NET page with the directive

<%@ Import Namespace="System.Xml" %>

The XmlTextWriter

XmlWriter is an abstract class that is implemented as an extended XMLTextWriter class. The XmlTextWriter writes a sequence of XML nodes one element at a time. Output can be written to an XML file, although other streams of output data can be produced. It can create a new file or overwrite an existing file. Its non-cached writing techniques provides very fast generation of an output stream.

How to implement custom HttpContext for each request under class that implements IHTTPHandler


Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If

Custom Control Design-Time SiteMap Provider Error


Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
