Using the Wizard control of ASP.NET |
|
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 going to see how to use this control in a typical situation of user registration. |

Using Extension Methods |
|
How often do you want to modify existing classes to have extra methods? Quite often. Right? When you have source code of the classes under consideration at your hand then things are easy. You probably just add the extra methods to those classes. What if you don't have source code? Well. In such cases one approach is to inherit the existing classes and add extra methods to the child classes. However, this way may not be always correct and possible in terms of your application design and OO principles. Luckily, C# offers a quick way to extend your class functionality through a feature known as Extension Methods. Extension methods allow you to extend existing types without inheriting them. This article is going to throw some light on this handy feature.

Working with Binary Large Objects (BLOBs) Using SQL Server and ADO.NET |
|
Sometimes, your data is not limited to strings and numbers. You need to store a large amount of data in a SQL server table. Documents, raw files, XML documents and photos are some examples. SQL sever provides special data types for such large volumes of data. In this article, I will discuss how to read and write Binary Large Objects (BLOBs) using SQL Server 2005 and ADO.NET. |

Using LINQ in ASP.NET (Part 4) |
|
In the Part 1 and Part 2 of this series we discussed how to use LINQ to SQL features to query and manipulate data. Part 3 introduced you with the inbuilt LINQ to SQL class designer. The LINQ to SQL class designer not only allows you to design classes visually but also saves reasonable amount of time otherwise needed to write equivalent code manually. Another such handy feature available to ASP.NET developers is LINQ Data Source Control. In this article I will explore this control with examples.

Tip: Fetching Random Rows From SQL Server |
|
Recently I needed to fetch random rows from a SQL server table. If you have an integer column then using RAND() function goes well. However in my case there was no number column. |

Using LINQ in ASP.NET (Part 3) |
|
In the Part 1 and Part 2 of this series we discussed how to use LINQ to SQL features to query and manipulate data. We also learnt to call stored procedures via LINQ to SQL. In the previous examples our approach was manual in that we ourselves created the custom data context and entity classes. Visual Studio comes with an inbuilt designer to perform the same task. This article will teach you how to use the designer and consume the created classes in your application. |

Using LINQ in ASP.NET (Part 2) |
|
In the Part 1 of this series I discussed the basic operations of LINQ to SQL. By default when you use LINQ to SQL queries as shown earlier, they internally use SQL statements i.e. INSERT, UPDATE, DELETE and SELECT. In many real world applications you use stored procedures. Luckily, LINQ to SQL has a way to call stored procedures from your application. It involves bit of a work as compared to almost automated way discussed earlier. In this article I will explain how stored procedures can be consumed using LINQ to SQL. |

Using LINQ in ASP.NET (Part 1) |
|
Language INtegrated Query or LINQ changes the way you write your data driven applications. Previously developers used to think and code differently to access different data stores such as SQL server, XML files and in-memory collections. The new LINQ based programming can take away the hassles involved while developing such applications. In this multi part series I am going to explain how LINQ capabilities can be used ASP.NET applications. |
