c# - Set control visible from other form

Question

I set the button visible property to false of Form2. How I will make the button(Form2) visible when I click a button(a button that also opens Form2) from Form1.

I tried this :

private void button1_Click(object sender, EventArgs e)
{
    Form2 f2 = new Form2();
    f2.Show();
    f2.button1.Visible = true;
    f2.button1.Location = new Point(200, 200);
}

Answer 1

Create a method in Form2

public void setButton1Visible(boolean flag){
      this.button1.Visible = flag;
}

You cannot access the button directly from Form1. (Actually you can,but it is not right way to solve it.

private void button1_Click(object sender, EventArgs e)
    {
        Form2 f2 = new Form2();
        f2.Show();
        f2.setButton1Visible(true);
    }
