i am very new in asp.net i got this code from some tutorial page i dont remember where be cose i have been reading so many tutorial websites.
here you can see the code in action
http://demo.xodus.is/xman-manager/aspxTest.aspx|||why are you doing a "select * from ..." and then an update...why not just an update and call the bindgrid sub at the end..
hth|||i am very new in asp.net can you show me how that is done|||just build your sql stmt use parameterized query and execute it..
sample code:
dim mysql as string
'set up your connection string
Dim oCmd As New OledbCommand(sSQL, oCnn)
mysql="update <table> set col1=@.colval,col2=@.colval where Id=@.Id"
'Add up the parameter, associated it with its value
oCmd.Parameters.Add("col1",value1 )
oCmd.Parameters.Add("col2",value2 )
oCmd.Parameters.Add("id",Idvalue )
oCnn.Open()
oCmd.ExecutenonQuery()
oCnn.Close()
you need to modify the above code with your table names, col names and values from textboxes ..etc and as i said earlier call the bindgrid() again when done.
hth|||thx allot it does work now
