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
