CustomValidator

[Philip Korolev]

Hi All. Tore most of my hair out trying to solve this already! Please allow me to keep the remaining two :-)

What I am trying to do is use customValidator to go to a database via a stored procedure and fish out a UserName value. If it finds it, I want it to return 1 and if not I want it to return 0. On the ASP.NET page I have a field called user_username that customValidator is pointing to as a control to validate. The subroutine for the validator and my stored procedure are below. I now have 37 instances of the username = pkorolev and I get 37 as the value returned by the stored procedure, however the point where I want the validator to invalidate the page, the code fails. So, I get a correct value returned by the database (Enterprise Manager test), I get this value correctly on the ASPX page as output but the IsValid bit fails. What am I missing, seetings perhaps???? I bet it is something really simple.
***********************
create procedure userAlreadyExists
@user_username nvarchar(100),
@valid int output
as
declare @userValid int

select @userValid = Count(*) from user_pass
where user_username = @user_username
set @Valid = convert(int, @userValid) -- in this line i am simply trying to ensure that value coming back as an iteger
**********************
CustomValidator SUB:

*********************
Private Sub custValUserExists_ServerValidate(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles custValUserExists.ServerValidate

Dim cnn As New SqlConnection(connection.SQlConnection)

Dim sdrUserExists As SqlDataReader

Dim cmdUserExists As New SqlCommand("userAlreadyExists", cnn)

Dim ctrlValue As Integer

Try

cnn.Open()

cmdUserExists.CommandType = CommandType.StoredProcedure

cmdUserExists.Parameters.Add("@user_username", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Input

cmdUserExists.Parameters("@user_username").Value = Trim(art_username.Text)

cmdUserExists.Parameters.Add("@Valid", SqlDbType.Int).Direction = ParameterDirection.Output

cmdUserExists.ExecuteNonQuery()

'the line below is for checking the value returned on the confirmation page
Session("DBRETVAL") = cmdUserExists.Parameters("@Valid").Value

If cmdUserExists.Parameters("@Valid").Value = 0 Then

args.IsValid = True

Else

args.IsValid = False

End If

Catch ex As Exception

lbltype.Text = ex.ToString

End Try

End Sub

Hi Philip
what is the value of the @valid parameter when you debug your page could
you please debug and see if it will enter the if statement correctly

Hi Hussein.

Thanks for the reply. @Valid = 46. There are 46 instances of pkorolev which successfully made it though :-(
