Problem : it is because you are just creating and displaying the new Form without adding controls on it.

Method 1 : You can Add controls to the Form created at runtime.

Try This: Adding Label on Form -similarly you can add other controls.

        Form rr = new Form();
        Label l1=new Label();
        l1.Text = "label 1";
        rr.Controls.Add(l1);
        this.Hide();
        rr.ShowDialog();

Method 2 : you can create the NewForm from IDE and add then add controls from DesignView.

Adding Form from Visual Studio IDE:

1. Right click on project
2. Select Add -> Windows Form...
3. Now Enter form your formname -> SampleForm
4. Now Add the controls on the newly created SampleForm
5. Display the newly created Form 

SampleForm sample=new SampleForm();
sample.ShowDialog();

i have a little helper function witch is this:

  private void ShowForm<T>() where T: Form, new ()
    {
        this.Hide();
        T form = new T();
        form.FormClosed += (s, e) => this.Show();
        form.Show();
    }

this is the main form witch works like a storyboard and for example when some one click a button and im going to display a new form i do this:

    private void SomeButton_Click(object sender, EventArgs e)
    {
        ShowForm<PublishersForm>();
    }

That's because you're opening basic Form but not your form (that is with controls).

Suppose your form class (which you've designed) is MyForm, so you should put it like 

  private void button2_Click(object sender, EventArgs e) {
    MyForm rr = new MyForm(); // <- MyForm not Form!
    rr.ShowDialog();
  }
