Hi,
You have to call Form1 in Form2's OK Button Click Event and Pass Textbox value as Parameter.
private void btnOk_Click(object sender, EventArgs e)
{
using (Form1 form=new Form1 (Textbox1.Text))
{
form.Show();
}
}

On Form1 Constructor:
public Form1(string text)
{
InitializeComponent();
Label1.Text=text;
}
