Question

I have made a secondary form in my project which can get data from the main form, and should pass some out to the main form when a button is clicked.
here is the code:

Add.cs:

        private void button1_Click(object sender, EventArgs e)
        {
            main ma = new main();

                ma.optionType = "add";
                ma.optionName = txtName.Text;
                ma.optionURL = txtURL.Text;
                ma.optionInterval = "12";
                //What should I pass here?


            this.Close();
        }

main.cs:

  private string opt;// create a property
        public string optionType
        {
            get
            {
                return opt;
            }
            set
            {
                opt = value;
            }
        }
        private string opt2;// create a property
        public string optionName
        {
            get
            {
                return opt2;
            }
            set
            {
                opt2 = value;
            }
        }
        private string opt3;// create a property
        public string optionURL
        {
            get
            {
                return opt3;
            }
            set
            {
                opt3 = value;
            }
        }
        private string opt4;// create a property
        public string optionInterval
        {
            get
            {
                return opt4;
            }
            set
            {
                opt4 = value;
            }
        }

My problem is that I don’t know when to try to fetch the data coming from add.cs after button1 (in add.cs) was clicked. With what event should I check if the data came?

I just changed it to this:
add.cs:

 public string optionType { get; set; }
 public string optionName { get; set; }
 public string optionURL { get; set; }
 public string optionInterval { get; set; }
 public int yCoord { get; set; }
