Dispalying Records into Grid View Create a file called and create a Grid View something like displayed into the picture.

Insert) by passing first Name, last Name, age as parameter.

I am assuming that I have to play with record of persons (First Name, Last Name, Age) and I will refer only these data through out this article. just to give you flexibility to not show scroll bar for long screens.

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). As we don't have any business logic here so simply instantiate the Person DAL3 class of DAL and call methods. Now we have all set to go, now just run your project and try inserting records. Now, create a class named Person BAL3 into App_Code folder by right clicking it and write respective methods for calling Insert, Delete, Update and Load methods of Data Access Layer class file (Person DAL3) (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 BAL and add reference of this project into your Presentation Layer). In the above method, I am instantiating Person BAL3 and calling the Update method by p[assing required parameters.(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.Here, I have assumed that you will create the respective stored procedure yourself into the database or you may download attachment from using System; using System. In this case definitely the passing number of variable will not be good idea.Un detalle de este método es que luego de despegar el mensaje el botón realiza el postaback de la pagina invocando los eventos del mismo.: Este no define el evento en el html del control, sino que es en el evento Form_Load que se asigna haciendo uso de la colección Attributes.NET with C# 3-Tier architecture generally contains UI or Presentation Layer, Business Access Layer (BAL) or Business Logic Layer and Data Access Layer (DAL). Independence - layers are established so that if one is modified (to some extent) it will not affect other layers. Reusability - As the layers are seperated, it can exist as a module that can be reused by other application by referencing it.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.
