All correct but there is another way if you want close the window in your code:

Suppose that the button ID is "ContineButton" and the click event handler name is "ContineButton_Click"

protected void ContineButton_Click(object sender, EventArgs e)
{
    this.ClientScript.RegisterClientScriptBlock(this.GetType(), "Close", "window.close()", true);
}
