Presentation Layer (UI) Presentation layer cotains pages like or windows form where data is presented to the user or input is taken from the user. Hope this article helped you understanding 3-Tier architecture and desiging it.

Connect me on | https://twitter.com/sheonarayan | Hi, Nice article; Well and simply explained.

Did you create the source code for the page manually or did you use some type of wizard to do this? tulsi Hi Sheo Narayan, Indeed a very useful article with easy to understand example.

I'm use to binding the gridview to the sqldatasource, but want to learn more on the way you created this page. But Sheo Narayan, as in this example you are creating DAL and BAL inside App_Code, I need an architecture wherein the DAL and BAL should be outside App_Code folder.

Lets create a form that will have three textboxes for First Name, Last Name and Age.

So for example, configure a sqldatasource and then bind it to the grid view control. For further you can refer to this page One more question....For the ease of understanding, I have created BAL, DAL into the App_Code folder. pre 2) Can you post other similar article with Ajax? Because in practice we expect the delete to be performed with confirmation and also in details screen. Add new / Edit in 2 different tab panels - to have better usability. Regards, Sreedhar Thanks Vansree for your suggestions. Regarding pre class, I will let the webmaster know about it. As far as article on Ajax is concerned, I will try my best to post few articles on Ajax in coming days. Regards This is simpler example for 3-Tier Architecture.In real scenario, you should create separate projects for BAL, DAL (as Class Library) and UI (as Web project) and reference your BAL into UI. I wonder if you can come up with the same but using Ajax Tabs. Like having add button in Grid View will switch you to Tab Panel (Add new) and then perform the add ... But would like to see if you can come up with Tabs and your example above. I have one question about passing the data between layers.Data Access Layer Lets proceed with desiging 3-Tier architecture. Add a class named by right clicking App_Code folder. Because the new buzz in the industry is to use Ajax Tab Panels. As you have used four variables to pass data from one layer to another (person ID, first Name, last Name, age).(In my case I have a 3-Tier folder inside App_Code folder, you can directly add inside App_Code or you can create a separate project for DAL and add reference of this project into your BAL.) and copy-paste folowing code (Your can overwrite your default written code for the class file by pasting this code). Tab Container (Container to hold GV, Add, Edit) First Tab Panel ... Now think the Scenario when the number of fields are too much.
