I having problem saving the data to SQL Server.

Here is the code on my form :

private void btnSave_Click(object sender, EventArgs e)
        {
           DataRow row =  this.dsPolicyNotes.Tables[0].NewRow();
           row["PolID"] = this.PolID;
           row["Note"] = this.rtbNotes.Text;
           row["edate"] = DateTime.Now;
           this.dsPolicyNotes.Tables[0].Rows.Add(row);

                // Now proceed to call the update method in the biz object
           this.oPolicyNotesBiz.UpdateDataSet(dsPolicyNotes);

         }

Here is the code in my Business layer :

 public void UpdateDataSet(DataSet ds)
      {
        // Here maybe I can put someloig
        this.oDA.UpdateDataSet(ds);
   
      }

And here is my code in my DataAccess layer that is not updating in
Sql Server

public void UpdateDataSet(DataSet ds)
        { 
            DataSet dirtyDS = ds.GetChanges();
            //Take action.
            ds.AcceptChanges();

            SqlConnection con1  = new SqlConnection(this.connectionstring);
            con1.Open();
            SqlDataAdapter sqlAdapter1 = new SqlDataAdapter();
            sqlAdapter1.Update(ds,"PolicyNotes");
            con1.Close();
        
        }

The Update is not working an nothing is inserted in Sql server.

Any help is appreciated.

Thanks,
Sergio
