2x volané události v ASP.NET - proč? – .NET – Fórum – Programujte.com

Zdravím,
mám jednoduchý kód v ASP.NET:

public partial class _Default : System.Web.UI.Page 

{

    int count = 0;

    /*

     *      FÁZE ZPRACOVÁNÍ UDÁLOSTÍ V ASP.NET:

     *      

     * 1)   Page.Init();

     * 2)   Page.Load();

     * 3)   TextBox.TextChanged();

     * 4)   Button.Click();

     * 5)   Page.PreRender();

     * 6)   Page.Unload();

     * 

     */



    protected void Page_Init(object sender, EventArgs e)

    {

        // init

        lblInfo.Text += "1. event: Page_Init(); ";

        count++;

    }

    protected void Page_Load(object sender, EventArgs e)

    {

        // load

        lblInfo.Text += "2. event: Page_Load(); ";



        if (Page.IsPostBack)

        {

            lblInfo.Text += "(<strong>PostBack!</strong>)";

        }



        lblInfo.Text += "";

        count++;

    }

    protected void Page_PreRender(object sender, EventArgs e)

    {

        // prerender

        lblInfo.Text += "3. event: Page_PreRender(); ";

        count++;

        lblInfo.Text += "Total count: " + count.ToString() + "";

    }

    protected void Page_Unload(object sender, EventArgs e)

    {

        // unload

        lblInfo.Text += "4. event: Page_Unload(); ";

        count++;

    }

}
