I have a poll when I test it. no matter what option I select it always votes value 1. not sure whats wrong. and when I add the cookie to record the vote it does not vote at all.  But for now I just need to know why it only votes for value one.


stored procedure

       (
       @Pk_OptionId  INT
       )
 
AS
--     GETS THE CURRENT NUMBER OF VOTES FOR THAT OPTION
       DECLARE      @i_NumberOfVoteS INT
       
       SELECT @i_NumberOfVotes = Votes
       FROM   PollOptions
       WHERE  PK_OptionId = @Pk_OptionId
 
       UPDATE PollOptions
       SET           Votes = (@i_NumberOfVotes + 1)
       WHERE  PK_OptionId = @Pk_OptionId
 
       RETURN



Protected Sub btnVote_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnVote.Click
        RecordVote()
 
        'If Response.Cookies("Voted") Is Nothing Then
        '    Response.Cookies("Voted").Value = "Voted"
        '    Response.Cookies("Voted").Expires = DateTime.Now.AddDays(1)
 
        '    lblError.Visible = False
 
        '    '   Checks if the user can still vote by using cookie
        '    RecordVote()
        'Else
        '    lblError.Visible = True
        'End If
        'Response.Write(Response.Cookies("Voted"))
        '' Response.Redirect("test.aspx")
    End Sub
 
    Private Sub RecordVote()
        Dim strConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings.Item("Conn").ToString()
        Dim sqlConn As New SqlConnection(strConnString)
 
        sqlConn.Open()
        Dim sqlCmd As New SqlCommand()
 
        sqlCmd.CommandText = "IncrementVote"
        sqlCmd.CommandType = Data.CommandType.StoredProcedure
        sqlCmd.Connection = sqlConn
 
        '   Creation parameters
        Dim sqlParamQuestion As New SqlParameter("@PK_OptionId", Data.SqlDbType.Int)
 
        sqlParamQuestion.Value = rdoPollOptionList.SelectedValue
 
        sqlCmd.Parameters.Add(sqlParamQuestion)
 
        '   Execute stored procedure
        sqlCmd.ExecuteNonQuery()
 
        '   Close connection
        sqlConn.Close()
    End Sub

Here are troubleshooting options:
1: Execute your StoredProc directly from SqlServer and see if it is working as desired.
2: set breakpoint at line:
------> sqlParamQuestion.Value = rdoPollOptionList.SelectedValue
Confirm the "rdoPollOptionList.SelectedValue" has desired value.

Post your observations.
Now a question: How is your rdoPollOptionList DataBound? i.e. dynamically in code-behind?
If so post that code....make sure that you DataBind it once only i.e. Not Page.IsPostBack.

I excuted the stored procedure that works great.

I used
  If Page.IsPostBack Then
            ' RecordVote()
            Dim strConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings.Item("Conn").ToString()
            Dim sqlConn As New SqlConnection(strConnString)

            sqlConn.Open()
            Dim sqlCmd As New SqlCommand()

            sqlCmd.CommandText = "IncrementVote"
            sqlCmd.CommandType = Data.CommandType.StoredProcedure
            sqlCmd.Connection = sqlConn

            '   Creation parameters
            Dim sqlParamQuestion As New SqlParameter("@PK_OptionId", Data.SqlDbType.Int)

            sqlParamQuestion.Value = rdoPollOptionList.SelectedValue

            sqlCmd.Parameters.Add(sqlParamQuestion)

            '   Execute stored procedure
            sqlCmd.ExecuteNonQuery()

            '   Close connection
            sqlConn.Close()

instead of not Page.ispostback because the other way did not execute.

But it only finds Value 1 not value 2, 3 ect.

yes but how is your rdoPollOptionList getting its values?
Anythingin your Page_Load method?
Also you misunderstood ...i did NOT mean to put your StoredProc call into IsPostback....that call is fine....
What I am asking is about your RadioButtonList....how is it getting the option values?
Can you share all code related to your RBL

Private Sub DisplayPoll()
        Try
            Dim ds As DataSet = getActivePoll()

            '   Displays the poll
            lblPollQuestion.Text = ds.Tables(0).Rows(0)("Question")

            Dim i As Integer = 0
            For Each dr As DataRow In ds.Tables(1).Rows
                rdoPollOptionList.Items.Add(dr("Answer"))
                rdoPollOptionList.Items(i).Value = dr("PK_OptionId")
                rdoPollOptionList.SelectedIndex = 0

                i = i + 1
            Next
        Catch ex As Exception
            Throw ex
        End Try

    End Sub

The radio button is getting the option value from the database.

Put the Call to this method in If Not Page.IsPostBack
