Return the hidden FORM from another FORM

Question

I have two forms Form1 and Form2

I open Form2 from Form1 on button_Click

 Form2 obj2 = new Form2(); this.Visible = false; obj2.Show(); 

then I want to return Form1 Visible (when disposing Form2 ) in the same state of the controls that I left .....

Answer 1

Your Form2 does not know anything about Form1 . He will need a link to it (you can do this by adding the Form type property to Form2 and assign it Form1 after construction):

 //In Form2 public Form RefToForm1 { get; set;} //In Form1 Form2 obj2 = new Form2(); obj2.RefToForm1 = this; this.Visible = false; obj2.Show(); //In Form2, where you need to show Form1: this.RefToForm1.Show(); 

Answer 2

A deferred response will work fine, another option with the same result will expose a public event in Form2, called, for example, “AfterClose”, call it when Form2 deletes, and have Form1 add an event handler where it is displayed. Let me know if you are interested, and I will give an example code.
