Are you sure your sql update query is working correctly? If so, you need to rebind the new data after updating to reflect the new values...

Hi,

I think values from dropdownlist boxes are getting saved into the database . So in order to show the updated values into dropdownlist you have to write the Select sql query to get the updated records from the database and display the records into dropdownlist.
e.g. In the page load event you can write the following code:

Expand|Select|Wrap|Line Numbers
  1.   Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  2.  
  3.                  ''Get the updated data from db
  4.                   Dim sql as string = "Select * from Tablename"
  5.  
  6.                  ''Fill the updated data into dataset   
  7.  
  8.                  Dim con as new oledbConnection
  9.  
  10.                   Dim ds as new dataset
  11.                                  Dim da as new  OledbdataAdapter(Sql,con)
  12.  
  13.                   da.Fill(ds)
  14.  
  15.                   'Display updated data into dropdownlist  
  16.                   dropdownlist1.datasource= ds
  17.                   dropdownlist1.databind() 
  18.                 End Sub

I have a table in a PG 7.4.1 database with 380 duplicate rows, including duplicate oid and primary key values. Looking through our backups, the duplicates did not exist before Friday, 02/06/2004. I'm assuming neither pg_dumpall nor restoring from a pg_dumpall file will eliminate such duplicates. We upgraded from 7.3.4 to 7.4.1 on 02/02/2004. What can cause these duplicates? The server has had several system crashes over the past...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
