3-Tier architecture is a very well know buzz word in the world of software development whether it web based or desktop based. Below is the code for BAL (Your can overwrite your default written code for the class file by pasting this code). You can also navigate to another page your created (list.aspx) and try updating, deleting records.

In this article I am going to show how to design a web application based on 3-tier architecture. Code for Business Access Layer using System; using System. By using 3-Tier architecture in your project you can achive 1.

ASP Code EDIT: I used the SQL Profiler to see what parameters are being sent in the stored procedure.

rowupdating event fires twice-14rowupdating event fires twice-67rowupdating event fires twice-80

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.

Panel with card layout (called viewport and I will refer to it as such from now on) defining the important sections of my application.

This occurs on multiple panels and I have determined that that even a simple panel with nothing but some HTML in it will fire the activate event twice. This solves the problem when running actions from panel, but in new MVC model one should set all the actions in controller and controller only.

Understanding this simple difference between the two methods can save you hours of work! NET AJAX Update Panel, then you cannot use the Client Script.

Register Startup Script to call a Java Script function during a partial-page postback.

Had we used the 'Register Client Script Block', the browser would have executed the Java Script before the text box is on the page.

Therefore, the Java Script would not have been able to find a ‘txt Master’ and would give a control not found error.

sanitize "down" to do nothing when last Active is on last grid row Changes 2 and 3 are probably not important for you, because select Row handles this situation and does nothing.

I just needed to have clean calls to select Range for my server notifications.

I have no idea how to set buffer on function in controller.
