Question

I have 2 Forms. At init of 1st form I have code:

public App_Index()
        {
            InitializeComponent();

            this.Hide();

            Authorization loginForm = new Authorization();
            loginForm.ShowDialog();
        }

And if I push on Close button [X] on Form2 — App_Index(Form1) Form do .Show(); But no code in Form2 about this. I want to close Form1 and Form2 if I push [X] on Form2. How can I do this?

Answer 1

How about this? This closes the current form if the dialog is cancelled.

public App_Index()
{
    InitializeComponent();

    this.Hide();

    Authorization loginForm = new Authorization();
    if (loginForm.ShowDialog() == DialogResult.Cancel)
        Close();
}
