Because I am trying to implement this but not getting it.
The folder structure what i am looking for the 3 layers should be like this; --PRESENTATION LAYER --- (this is the startup project) --APP_CODE --APP_DATA --Web.config --DAL --cls Employees --cls Transport --BAL --cls Load --cls Get Employees this is what i need to implement. thanks & regards nazir k Nazirk, You need to use Visual Studio to create BAL and DAL as separate projects.
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.
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).
Business Access Layer (BAL) or Business Logic Layer BAL contains business logic, validations or calculations related with the data, if needed. Data Access Layer (DAL) DAL contains methods that helps business layer to connect the data and perform required action, might be returning data or manipulating data (insert, update, delete etc). Connect me on | https://twitter.com/sheonarayan | Hi, Nice article; Well and simply explained. Lets create a form that will have three textboxes for First Name, Last Name and Age. Now we have to write our Presentation Layer that will use our Business Access Layer methods. Html Controls; /// Till now we haev our Business Access Layer and Database Access Layer ready.How we can pass a large amount of data from one layer to another. Regards Haneef Dear Sir, Thanks so much for such a nice article, I am sure it will help a lot of new . I have a small problem while using your code, I am not being able to enter and save a date field in a plain textbox (also tried using a datepicker).
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.
