Asp net updating database from dataset

If you store the actual file data in your database, then you must create an action to retrieve that data, write it to a response, add all the appropriate caching and expires headers to that response (for the love of all things good), etc., which also means that the entire ASP.

NET machinery must spin up in order to serve that file to the user.

For example, in my case I wanted to pull latitude longitude information from a SQL Server database and then use them to insert pushpins on google map. So I have decided to write a user control which can take care of javascript part and allows me to concentrate on serverside functions.

Data Bind() Dim columncount As Integer = grid View.

" End If End Sub Protected Sub grid View_Row Editing(By Val sender As Object, By Val e As Grid View Edit Event Args) grid View. New Edit Index load Stores() End Sub Protected Sub grid View_Row Updating(By Val sender As Object, By Val e As Grid View Update Event Args) Dim stor_id As String = grid View.

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.

Page Private con As New Sql Connection("Data Source=.; Initial Catalog=pubs; User ID=sa; Password=*****") Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load If Not Is Post Back Then load Stores() End If End Sub Protected Sub load Stores() con.

Google has provided a very reach APIs to use it in our own application.

But we need some short of javascript knowledge in order to use it.

Find Control("txtaddress"), Text Box) Dim city As Text Box = Direct Cast(grid View.

, the connection to the database was continually maintained, unless explicitly closed.

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.
