Question

I have a class that inserts a TextBox value and a FileUpload image into the SQL Server. I’m executing all the class in the Wizard1_FinishButtonClick event. I have 4 steps in Wizard. All the classes are getting executed and inserted other than InsertCert() class.
I executed same codes in a simple .aspx page and the values are inserting into the DB.

Where ‘m I going wrong? Following is the class and Wizard1_FinishButtonClick.

public void Insertcert()
        {
            String KKStech = @"Data Source=USER-PC\SQLEXPRESS;Initial Catalog=KKSTech;Integrated Security=True";
            SqlConnection conn = new SqlConnection(KKStech);
            String insertstring2 = @"insert into Cert(CertName, CertLogo)
                                       values(@CertName, @CertLogo)";
            SqlCommand cmd = new SqlCommand(insertstring2, conn);
            cmd.CommandText = insertstring2;
            cmd.CommandType = CommandType.Text;
            try
            {
                if (FileUpload1.HasFile)
                {
                    byte[] productImage = FileUpload1.FileBytes;
                    conn.Open();
                    cmd.Parameters.AddWithValue("@CertName", TextBox18.Text);
                    cmd.Parameters.Add("@CertLogo", SqlDbType.VarBinary).Value = productImage;
                    cmd.ExecuteNonQuery();

                }

            }

            catch (Exception ex)
            {
                throw ex;
            }

            finally
            {
                conn.Close();
            }

        }

This is the final class where all the classes are inserted.

 protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e)
        {

            InsertInfo();
            Insertcert();
            Insertaddress();
            Insertskills();

        }

Put the cursor on the “if (FileUpload1.HasFile)” line and hit F9; this will put a breakpoint on that line (you’ll see a red circle in the left hand margin). Now debug your program (F5). When the breakpoint is hit, hover the mouse over the “HasFile” and you should see a tool tip which gives the value. If the value is false, this explains why the insert is not happening.
