Can someone please help me with the following I am getting a mappings exception as follows: 'Update unable to find TableMapping['MovTable1'] or DataTable 'MovTable1'.

This happens when I try to save the changes made when I have entered details onto a datagrid which is linked to a sql database..

the updated code I am now using is below....thanks for any help.


//code when loading data grid//
private void button3_Click(object sender, System.EventArgs e)
{ Form3 F3 = new Form3();
SqlCommandBuilder cmdBuilder = new SqlCommandBuilder(MovAdapt);
MovAdapt.TableMappings.Add("MovMapping", "MovTable1";
Mcon.Open();
Movcmd.CommandText = "SELECT * FROM MovTable1";
MovAdapt.SelectCommand = Movcmd;
MovAdapt.Fill(Movset1, "MovTable1";
F3.dataGrid1.DataSource = Movset1;
F3.Show();
}

---

//code behind the save button//
private void button1_Click(object sender, System.EventArgs e)
{
F1.MovAdapt.Update(F1.Movset1, "MovTable1";
Form1.Mcon.Close();

}
