title: How to go back to the previous form in c#?
body: <p>I've been looking for a way to go back to the previous form in c#. I am building a Bike Builder program, and basically it let you view your desired parts, and go back to previous form and edit your shopping cart.</p>
  
  <p>Form 2 will be the Shopping form, where you can select/deselect your product.
  Form 3 will be a review form, it will display how many parts you have been put in your cart so far, display the total. In form 3, there will be a button called "BACK", it will let you to go back to form 2 and update your cart.</p>
  
  <pre><code>// This is form 2
  public partial class frmSelectParts : Form
  {
  // variables and functions
  // .......
  
      public frmSelectParts()
      {
          InitializeComponent();
          this.WindowState = FormWindowState.Maximized;
      }
  }
  
  //This is form 3
  public partial class frmYourCart : Form
  {
      public frmYourCart()
      {
          InitializeComponent();
          this.WindowState = FormWindowState.Maximized;            
          cbbShipping.Items.Add("Standard 5 - 10 days");
          cbbShipping.Items.Add("Express 3 - 5 days");
          cbbShipping.Items.Add("Over night 1 day");
      }
  }
  </code></pre>
