if you want to get values from contact form then you should assign controls' modifier to public

//MAIN FORM
//First method 
private void btnInsertContact_Click(object sender, EventArgs e)
{
    frmContact.FormClosed += new EventHandler(ContactForm_Closed);
    frmContact.ShowDialog();
}
private void ContactForm_Closed(object sender, EventArgs e)
{
     //Write ur code here
}

//Second method 
private void btnInsertContact_Click(object sender, EventArgs e)
{   
    frmContact.ShowDialog();
    write ur code here.
}

Form.ShowDialog() is a blocking call. The program flow stops at this method until the method returns. The ShowDialog() method returns when the user closes the form.

You can simply update your information in the main form after calling ShowDialog():

private void btnInsertContact_Click(object sender, EventArgs e)
{
    frmContact.ShowDialog();

    // ToDo: Insert your code for updating the main form here
}

The ShowDialog function displays a modal dialog box and is therefore blocking. In plain English, that means that the ShowDialog function will not return (yield execution) until after the dialog box has been closed (either by the user clicking OK, Cancel, or some other button you provide).

So all you need to do is place your synchronization code after the call to ShowDialog. (Of course, you might want to check the DialogResult property to ensure that the user clicked the OK or Yes button!)
