Question

I have been trying to add new information to my database from a Windows Form (Gridview). This is the method I came up with (but it doesn’t work):

private void agregarProducto(string id_producto, string id_proveedor, string id_categoria, string cantidad, string precio_actual, string codigo_barras)
{
    MySqlCommand cmd = new MySqlCommand();

    using (cmd = cn.CreateCommand())
    {
        cmd.CommandText = "INSERT INTO productos(id_producto, id_proveedor, id_categoria, cantidad, precio_actual, codigo_barras) VALUES (@id_producto, @id_proveedor, @id_categoria, @cantidad, @precio_actual, @codigo_barras)";
        cmd.CommandType = CommandType.Text;

        cmd.Parameters.AddWithValue("@id_producto", tbId_Prod);
        cmd.Parameters.AddWithValue("@id_categoria", tbId_categoria);
        cmd.Parameters.AddWithValue("@id_proveedor", tb_Id_proveedor);
        cmd.Parameters.AddWithValue("@cantidad", tbCantidad);
        cmd.Parameters.AddWithValue("@precio_actual", tbPrecioActual);
        cmd.Parameters.AddWithValue("@codigo_barras", tbCod_barras);

        cn.Open();
    }
}

This is the event that’s is supposedly calling it:

private void btAgregarNuevo_Click(object sender, EventArgs e)
{
    agregarProducto(tbId_Prod.Text, tb_Id_proveedor.Text, tbId_categoria.Text, tbCantidad.Text, tbPrecioActual.Text, tbCod_barras.Text);
}

Am I missing something?

You haven’t executed the sql. Do this after you open the connection

cmd.ExecuteNoneQuery();
