Answer 1

in your Form1 class code:

private void form2btn_Click(object sender, EventArgs e)
{
    Form form2 = new Form2(FirstName.Text + " " + SecondName.Text, Pay.Text);
    form2.ShowDialog();
}

your Form2 class code:

public class Form2 : Form
{
    public Form2(string name , string pay)
    {
        Form form3 = new Form3(name, pay);
        form3.ShowDialog();
    }
}

your Form3 class code:

public class Form3 : Form
{   
    public Form3(string name , string pay)
    {
        NameTextBlock.Text = name;
        PayTextBlock.Text = pay;
    }

}

Answer 2

You can do this, on button click in form 1,

 private void btnTransfer_Click(object sender, EventArgs e)
        {
            Form3 frmdisplay = new Form3(txtFirstName.Text.ToString(), txtSecondName.Text.ToString(), txtPay.Text.ToString());
            frmdisplay.Show();
        }

and show it in form 3 like this,

 public Form3(string Firstname,string Lastname ,string Pay)
        {
            InitializeComponent();
            lblName.Text = "Your name is" + Firstname +" "+ Lastname ;
            lblPayment.Text = "Your payment is" + Pay;

        }

Answer 3

Step 1: Add a property in form2 to set the labels' text

public string Name
 {
      set{label1.Text=value;}
 } 

Step 2: In form1's button click event handler add the following code.

private void button1_Click(object sender, System.EventArgs e)          
 {
      Form2 frm=new Form2();
      frm.Name=txt1.text;
      frm.Show();
 }           

You can add the properties on need basis

From3

    public void Message(string firstname, string lastname, string pay)
    {
        lblName.Text = "Your name is" + firstname + " " + lastname;
        lblPayment.Text = "Your payment is" + pay;
    }

From1

        public Form1()
        {
            InitializeComponent();
        }

        public delegate void SendMessage(string Firstname, string Lastname,string Pay);
        public event SendMessage OnSendMessage;

        private void button1_Click(object sender, EventArgs e)
        {
            Form3 from3 = new Form3();
            OnSendMessage += from3.Message;
            OnSendMessage(Firstname.Text, Lastname.Text, Pay.Text);
            from3.Show(); 
        }

Answer 5

Assuming you are trying to load data into Form3 after Form1 presses the "Form 2" button, you need to: 1. Name your controls 2. Set your Form3 controls to the same values as those from Form1

Example which uses guesses for your names (since you posted no code):

var resultDialog = new Form3();
resultDialog.lblFullName.Text = this.txtFirstName.Text + " " + this.txtLastName.Text;
resultDialog.lblPayment.Text = this.txtPayment.Text;
