InitializeComponent();
}

private void productsBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{

}

private void Products_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'usersDbDataSet.Products' table. You can move, or remove it, as needed.
this.productsTableAdapter.Fill(this.usersDbDataSet.Products);

}

private void metroButton1_Click(object sender, EventArgs e)
