Make an Event When Second Form IsClosing

Let me say I have 2 forms

1st form name is : Form1

Consists from : 1 Button and it's name is Button1

This Button is Public from its properties and have an OnClick event

The event is:

        private void Button1_Click(object sender, EventArgs e)
    {
        Form2 form2 = new Form2();
        form2.Show();
        Button1.Enabled = false;
    }

2nd Form name is : Form2

Consists from : nothing

But there's a FormClosing event

The event is:

        private void Form2_FormClosing(object sender, FormClosingEventArgs e)
    {
        Form1 form1 = new Form1();
        form1.Button1.Enabled = true;
    }

Which means Button1 from Form1 should be Enabled again.

The problem nothing happens when the Form2 is Closed

I thought that event is incorrect but i'm not really sure

Any help is appreciated

You need to pass the instance of Form1 to Form2, that way you have access to the object/form...

public class Form2
{
  private Form1 _Form1;
  public Form2(Form1 form1)
  {
     this._Form1 = form1;
  }

  private void Form2_FormClosing(object sender, FormClosingEventArgs e)
  {
      _Form1.Button1.Enabled = true;
  }    
}

...

public class Form1
{
  private void Button1_Click(object sender, EventArgs e)
  {
    Form2 form2 = new Form2(this); //pass "this", ie the instance of Form1
    form2.Show();
    Button1.Enabled = false;
   }
 }
