Download source code for 3-Tier Architecture in ASP. Seperation - the functionality is seperated from the data access and presentation so that it is more maintainable 2.
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.
Hello James, Concerning your suggestion, unfortunately we are going to decline it, because we can't change the ASPx Grid View in this manner.
By design the ASPx Grid View is based on the Data Controller which provides more features, and it is more flexible than the ASP: Grid View. By design it obtains keys from the datasource only.

In previous post we discussed how to create 3 – tier architecture application using c#.
For this demo application, I have taken a very simple example. 1) Fix for the code block For the css 'pre', add new property 'min-width: 730px;' and add width nn percentage.
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.
What seems to happen is 'Grid View1_Row Updating' gets fired, at this point new English, new French, and new German all have the new values as they are passed into 'Logic. Then the update functions updates correctly, but once the 'Grid View1_Row Updating' sub ends, it seems to call Logic.
Update another time, and this is where the new values get lost for French and German (datakeys) but not English.
