You are not transferring any information between the forms. In this case the information you should be transferring is the Visible property of a control on the form. It is not as simple as just trying to set the value from outside the form that contains the control.

Have a look at @Original-Griff's series of tips on the subject, starting with Transferring information between two forms, Part 1: Parent to Child[^] (also contains links to the other two)

i just start Programming and start Learn From Internet and from my Past Mistakes, so can you explain me in easy way how i solve this Problem just some help

Actually the tips I provided the link to explain several easy ways to do this. I see phil.o has posted an explicit answer. That concept of passing something to the form in the constructor was the very first thing that article suggested. As you say you are trying to learn from the Internet (not necessarily a good tactic) then I still recommend that series of Tips

Sir Chill60, i READ your shared link and download project source code for study and try to learn and thank you for sharing and answering my question

Solution 3

Your Open_Click method is calling ShowDialog before setting the Visible property of the button. ShowDialog is modal, which means that the code to set the Visible property will not be called until the second form is closed.

You could modify the constructor of Form1 to accept a boolean value setting the visibility of the button.
Status:

C#

public Status(Form1 _f1)
{
   InitializeComponent();
} 

Form1 f1;

private void Open_Click(object sender, EventArgs e)
{
   f1 = new Form1(this, false);
   f1.ShowDialog(this);
}

Form1:

C#

public Form1(Status _f3, bool buttonIsVisible)
{
   InitializeComponent();
   this.f3 = _f3;
   this.button1.Visible = buttonIsVisible;
}

// ...
