Question

When a user clicks the X button on a form, how can I hide it instead of closing it?

I have tried this.hide() in FormClosing but it still closes the form.

Answer 1

Like so:

private void MyForm_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing) 
    {
        e.Cancel = true;
        Hide();
    }
}
