I have noticed for some time now that when I go to select a control while in a sqlDataSource Wizard as a variable that it shows more than one control with the same name.  I am also having a problems with for next loops doubling the data inserted into database tables.  What might cause this?  I am running Windows Server 2003 and VS2005 with SQL 2005 on the same machine.  I remotely write my code from a Windows XP machine. 

Here is the for next loop:

Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim StudentUserName As String


        For i As Integer = 0 To GridView1.Rows.Count - 1
            Dim cb As CheckBox = CType(GridView1.Rows(i).FindControl("StudentCb"), CheckBox)


            'If it's checked, delete it...
            If cb.Checked Then
                'Programmatically access the CheckBox from the TemplateField
                Dim StepsTb As TextBox = CType(GridView1.Rows(i).FindControl("StepsTb"), TextBox)

                Dim Grade As Integer = 0
                If Not StepsTb.Text = "0" Then
                    Grade = StepsTb.Text
                End If
                Profile.Score = Grade
                'If it's checked, delete it...

                StudentUserName = GridView1.DataKeys(i).Value
                Profile.StudentUserName = StudentUserName

                If Page.IsValid Then
                    Try
                        InsertDs.Insert()
                        'ErrorLb.Text += Grade & " " & StudentUserName & " " & DateTextBox.Text & " " & ClassTb.SelectedValue & "</br>"

                    Catch ex As Exception
                        ErrorLb.Text += "The following error occured while trying to update the data: " & ex.ToString() & "<br/>"
                        ErrorLb.ForeColor = Drawing.Color.Red

                    End Try

                End If
            End If

        Next


        'ErrorLb.Text = "Your information was entered correctly. <br/> "
        ErrorLb.ForeColor = Drawing.Color.Green
        ErrorLb.Font.Bold = True

        GridView2.DataBind()
        FormView1.DataBind()
        FormView2.DataBind()
    End Sub

The code is designed to loop through a templated field's text box on a gridview and enter this information into sql if a check box is checked. 

Try renaming this variable:

Dim StudentUserName As String

Dim strStudentUserName As String

Of course you will have to rename it throughout the rest of the subroutine also.

Hope this helps!  Please mark the most helpful post as "Answer"

I problem was that the score integer was being sent outside the If then statement, and I had placed a text value of 0 in each text box in the gridview control's template which the score value was derived from.  By removing the value from the textbox and moving the score inside the if then statement the problem was solved.
