Passing values from form1 to form2 via button click to form2

Question

frmPlaceOrder is my form1. I need to pass the firstName, lastname and Address from this form to the second one which will do the other functions. I don't know how to do that.

namespace Lab1_OrderCake
{
public partial class frmPlaceOrder : Form
{
    public static CustomerInformation customer;
    public static Address address;

    public frmPlaceOrder()
    {
        InitializeComponent();
        customer = new CustomerInformation(txtFName.Text, txtLName.Text);
        address = new Address(txtAddress.Text, txtCity.Text, txtPC.Text, txtProvince.Text);

    }

    private void btnPlaceOrder_Click(object sender, EventArgs e)
    {


        DialogResult dlgMsg;
        if (txtFName.Text == "")
        {
            MessageBox.Show("Please enter first name", "Data Missing");
            txtFName.Focus();
            return;
        }
        if (txtLName.Text == "")
        {
            MessageBox.Show("Please enter Last name", "Data Missing");
            txtLName.Focus();
            return;
        }
        else
        {
            frmCakeOrder  newCust = new frmCakeOrder();
            this.Hide();
            newCust.ShowDialog();
            this.Close();

        }

    }
  }
}

The second form; after the first one has been filled out needs to take the values from form1 and display it with the other values(frmCakeOrder values) in the second form. It needs to be seen in the View and Order events when i click it.

here is the Second form:

namespace Lab1_OrderCake
{
public partial class frmCakeOrder : Form
{

    Order cakeOrder;
    public List<Cake> cakeList;
    public frmCakeOrder()
    {
        InitializeComponent();
        cmbTraditionalCake.SelectedIndex = 0;
        cakeOrder = new Order();
        gbCustomCake.Visible = false;
        this.Size = new Size(700,360);
        cakeList = new List<Cake>();

    } 

    private void bttnOrder_Click(object sender, EventArgs e)
    {
        DialogResult dlgMsg;
        dlgMsg = MessageBox.Show(cakeOrder.ToString(), "Confirm Order", MessageBoxButtons.YesNo, MessageBoxIcon.Information);

        if (dlgMsg == DialogResult.Yes)
        {  
            MessageBox.Show(cakeOrder.PrintConfirmation());

        }
        else
        { 
            MessageBox.Show ("The order has not been placed");
        }
        bttnReset.Focus();
        cakeOrder.ClearCart();

    }

    private void radCustom_CheckedChanged(object sender, EventArgs e)
    {
        if (radCustom.Checked)
        {
            cmbTraditionalCake.Enabled = false;
            gbCustomCake.Visible = true;
        }
        else
        {
            cmbTraditionalCake.Enabled = true;
            gbCustomCake.Visible = false;
        }
    }

    private void btnView_Click(object sender, EventArgs e)
    {
        DialogResult dlgMsg;

        cakeOrder.NumOfCakes=1;
        dlgMsg = MessageBox.Show(cakeOrder.ToString(), "Your order: ", MessageBoxButtons.YesNo , MessageBoxIcon.Information);
        if (dlgMsg == DialogResult.No)
        {
            cakeOrder.ClearCart();
            MessageBox.Show("Please enter and confirm your order!");
  }



    private void btnAdd_Click(object sender, EventArgs e)
    {

        if (radCustom.Checked)
        {
            string flavour, occasion;
            flavour = occasion = "";
            int layers;

            //for flavor
            if (radBanana.Checked)
                flavour = "Banana";
            else if (radChocolate.Checked)
                flavour = "Chocolate";
            else if (radVanilla.Checked)
                flavour = "Vanilla";

            if (radTier2.Checked)
                layers = 2;
            else if (radTier3.Checked)
                layers = 3;
            else
                layers = 1;

            if (radGraduation.Checked)
                occasion = radGraduation.Text.TrimStart(new char[] { '&' });
            else if (radWedding.Checked)
                occasion = radWedding.Text.TrimStart(new char[] { '&' });
            else occasion = radAnniversary.Text.TrimStart(new char[] { '&' });
            cakeOrder.AddCake(new Custom(flavour, occasion, layers));
        }
        else
        {
            cakeOrder.AddCake(new Traditional(cmbTraditionalCake.SelectedItem.ToString()));
        }
        cakeList.Add(cakeOrder);
    }


}
}

Answer 1

There are many ways to do this. Try it this way.

private void btnPlaceOrder_Click(object sender, EventArgs e) {
   string fname = textBox1.Text;
   frmCakeOrder frm = new frmCakeOrder(textBox1.Text);
   frm.Show();
} 

And in frmCakeOrder,

public frmCakeOrder(string fname) {
   InitializeComponent(); 
   textBox1.Text = fname; 
}
