I have form 1 with next button and form 2 with previous button. I was on form 2 then went back to form 1 using the previous button, but when I click the next button from form 1, my data on form 2 is gone. How do I keep that data?

This my code:

private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    staticVar = this;
    Form2 form2 = new Form2();
    form2.Show();
    this.Hide();
}

`var form2 = Application.OpenForms.OfType().FirstOrDefault(); if (form2 is null) { form2 = new Form2(); } form2.Show();`. – 41686d6564 stands w. Palestine Aug 11 '20 at 10:29
