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.
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.
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.
Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.
In the previous article , we learned how to create a simple Grid View at runtime .
Sql Client; public partial class _Default : System.
Open() Dim cmd As New Sql Command("Select * from stores", con) Dim da As New Sql Data Adapter(cmd) Dim ds As New Data Set() da.
Find Control("txtname"), Text Box) Dim stor_address As Text Box = Direct Cast(grid View.
Find Control("txtaddress"), Text Box) Dim city As Text Box = Direct Cast(grid View.
