Answer 2

If I got you right, are you trying like this?

into this?

in your Form1, add this event in your button:

    // button event in your Form1
    private void button1_Click(object sender, EventArgs e)
    {
        Form2 f2 = new Form2();
        f2.ShowDialog(); // Shows Form2
    }

then, in your Form2 add also this event in your button:

    // button event in your Form2
    private void button1_Click(object sender, EventArgs e)
    {
        Form3 f3 = new Form3(); // Instantiate a Form3 object.
        f3.Show(); // Show Form3 and
        this.Close(); // closes the Form2 instance.
    }

Answer 3

Use this.Hide() instead of this.Close()

Answer 4

For example, you have a Button named as Button1. First click on it it will open the EventHandler of that Button2 to call another Form you should write the following code to your Button.

your name example=form2.

form2 obj=new form2();

obj.show();

To close form1, write the following code:

form1.visible=false; or form1.Hide();

Answer 5

I would use a value that gets set when more button get pushed closed the first dialog and then have the original form test the value and then display the the there dialog.

For the Ex

1. Create three windows froms
2. Form1 Form2 Form3
3. Add One button to Form1
4. Add Two buttons to form2

Form 1 Code

 public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private bool DrawText = false;

    private void button1_Click(object sender, EventArgs e)
    {
        Form2 f2 = new Form2();
        f2.ShowDialog();
        if (f2.ShowMoreActions)
        {
            Form3 f3 = new Form3();
            f3.ShowDialog();
        }

    }

Form2 code

 public partial class Form2 : Form
 {
        public Form2()
        {
            InitializeComponent();
        }

        public bool ShowMoreActions = false;
        private void button1_Click(object sender, EventArgs e)
        {
            ShowMoreActions = true;
            this.Close();
        }


        private void button2_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }

Leave form3 as is

Answer 6

you may consider this example

//Form1 Window
//EventHandler
Form1 frm2 = new Form1();
{
    frm2.Show(this); //this will show Form2
    frm1.Hide();  //this Form will hide
}
