Set value to another form

Question

I have to form Form1 and Form2

Form1 source

namespace WindowsFormsApplication1
{
    public partial class Form1 :          


        

Answer 1

In Form2 you have to add a parameter for the Form1.

i.e.

// Form1
...
private void button1_Click(object sender, EventArgs e)
{
    Form2 frm = new Form2(this);
    frm.SetBtn = "teste test";
    frm.Show();
}
...

// Form2
public Form2(Form frm1)
{
    InitializeComponent();
    frm1.setLb = "test test";
}
