Entity Framework Add Remove Attach and Detach
Post navigation← PreviousNext →Posted on by Leon van Bokhorst The DbContext of Entity Framework lets us add, remove, attach and detach entities to and from it. Calling SaveChanges on the DbContext the Entity Framework performs different actions on entities dependant on their EntityState. So an added entity gets inserted, a removed entity gets deleted and so on.

Caching in ASP.NET

Wednesday, May 08, 2013 12:17:25 PM GMT
Caching in ASP.NET
Caching is one of the coolest features in Asp.net. Caching enables you to store the expensive data into Cache object and later retrieve it without doing expensive operations. A very common example where you want to use caching is datagrid paging. I am sure you all are familiar with datagrid paging which enables you to view the records in multiple pages. Each time you visit a different page all the records are fetched from the database. This becomes very expensive operation. Caching can save a lot of expe... (more)

Build a Web Chat Application using ASP.Net 3.5, LINQ and AJAX (in C# 3.5)
A Java Programmer friend of mine once asked me if I have ever built a web chat application. I said "No". He then asked me if I were to build a really simple, monitored, bare minimum, working web chat application, how long do I think will it take (something to that effect). I said, "I don't know". A few days had passed, one lazy evening, I was surfing the web looking for ASP.Net web chat applications. It seems that I can't find one that is simple enough to implement. So I decided to just build something s... (more)

Introduction Some times the data to be accepted from the user is too much and splitting the entire form into multiple logical sections is desirable. In classic ASP or even ASP.NET 1.x developers used to create multiple web forms each containing a  part of the total information thus creating a wizard. However, this approach was often proved to be complex and time consuming. ASP.NET provides Wizard server control that allows hassle free development of such web forms. In this article we are goi...
