Update Sql Table from datagridview c#

Question

Hi I have a datagriview and I add it a data source of a sql table

 this.fletera_facturasTableAdapter.Fill(this.indarDataSet2.fletera_facturas);
        // TODO: This line of code loads data into the 'indarDataSet1.fletera_facturas' table. You can move, or remove it, as needed.

and in the event of keypres i want to update the changes to sql if the user press "Enter" key on cell this:

 private void update_sql(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == (char)13)
        {
            fletera_facturasTableAdapter.Update(indarDataSet2.fletera_facturas);
        }
    }

i don't get any error but the sql table doesn't update

Answer 1

I find out the solution I just need to add this line

 private void update_sql(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == (char)13)
    {
        fletera_facturasTableAdapter.Update(indarDataSet2.fletera_facturas);
        **indarDataSet2.fletera_facturas.AcceptChanges();**
    }
}
