Question

I have 2 forms. One is the display form and the other is the where data is added to an array.

How do I start a function on the display form once the ok button has been clicked on the add to array form?

EDIT:

Let me rephrase. How would I go about calling a function that is in one .cs file, from another .cs file.

Form 1

private void menuItem1_Click(object sender, EventArgs e)
{
    Form2 form2= new Form2();
    form2.Owner = this;
    form2.ShowDialog(this);
}

Form 2

private void button1_Click(object sender, EventArgs e)
{
    Form1 form1 = new Form1();
    form1.myMethod();
}

Obviously, the form2 code is generating a new instance of form1.

How do I run the method of the form that opened the modal window?

Thanks

Answer 1

The owner of Form2 is a instance of Form1 so you can cast the owner to Form1 and call the method:

(this.Owner as Form1).myMethod();
