Difference Between Server.Transfer vs Response.Redirect

There is a common question for developers in Asp.net interview board that "What is the difference between Response.Redirect and Server.Transfer". In a common term we can use both to redirect the user from source page to destination page. But there are some differences in between Response.Redirect and Server.Transfer, which i want to share with you.

Response.Redirect:

1. A round trip occurs to the client before loading the destination page, which means after redirecting a page from source page to destination page a round trip occur into the client to update the address bar and history of the client browser. And also the destination page will be loaded by initiating a new request which is the 2nd request to the server.

2. To pass data in this mechanism you can easily use Query String or Session value.

Server.Transfer:

1.It is a single request from source page to destination page. The destination.aspx will be loaded from the server without a second request. Means it will not update the address bar and history of the browser.

2. You will get better performance.
3. You cannot use Query String.
4. To pass data between souce.aspx page to destination.aspx by using HttpContext object. Click here to use HttpContext object.
5. You can also use session object to transfer data.
6. Users can not bookmark the destination.aspx page.

GRIDVIEW GROUPING

When displaying data, we sometimes would like to group data for better user experience or when displaying long list of hierarchal data, we would want to display them in a tree view kind of structure. There is more than way of doing this, but I am going to explain achieving this functionality using AJAX Collapsible Panel Extender Control . Overview: I am going to use Adventure Works as datasource. Every product in Production.Product table belongs to a product sub category. We fetch handful of products and the sub categories they belong to from the database. Our objective is to list all the available sub categories and allow user to expand/collapse to look/hide the list of products belonging to each subcategory. Database Connection Added following entry under connectionStrings element in web.config . < add name = "Sql" connectionString="Data Source=(local); Initial Catalog = AdventureWorks ...

ADO.NET Concepts With example

COMMAND OBJECT  Command object is the biggest object in ADO.NET  It is the only object which can perform actions with database  It can be created directly using Command class or can be created using Connection.Create command (factory classes also contain creation of Command). Ex: SqlConnection sqlCon = new SqlConnection("......"); SqlCommand sqlCmd = sqlCon.CreateCommand();  Commands that we run depend upon the kind of query that we want to execute with database. All databases support two types of queries. i. Action Queries ii. Non-action Queries Action queries are those which change the state of database and which don‟t return any query results(though they return the number of records affected). Ex: Insert, Delete and Update statements Non-action queries are those which don‟t affect the database but return the results to the user. Ex: Select statement Method of execution of queries: Command object provides the following methods to execute queries: 1. Ex...

GRIDVIEW ZOOM IMAGE

When you have images in your GridView , you would most likely show them as thumbnails so as to not distort the whole layout. However user would want to look at the full image by clicking on the image or just hovering his mouse over it. In today’s applications, this is a basic requirement and there are just so many third party controls or plugins which would support this functionality. I am going do this conventional way using javascript way in this article. On top of it, I am also going to explain how to get images from database using HttpHandlers . Example: I am using Adventure Works as datasource. We fetch handful of products and bind them to the grid. When page is initially loaded, we retrieve products from Production . Product table and bind them to the grid. We display some product attributes such as Product ID, Product Number, Product Name, List Price and product’s thumbnail. When user hover his mouse on the page, we fetch the f...
