C# 如何向客户展示进度过程

我正在使用C#4.0，我希望在单击按钮后显示进度

protected void ASPxButton_cloture_Click(object sender, EventArgs e)
{
    tell user that procedure 1 begin
    do procedure 1.....
    tell user that procedure 1 finish

    tell user that procedure 2 begin
    do procedure 2.....
    tell user that procedure 2 finish

    etc...
}

我试过使用更新面板，但每个按钮只能使用一个。这意味着当我有5个程序时，我必须有5个按钮

我想要的是只点击一次按钮。

试试这个：

protected void ASPxButton_cloture_Click(object sender, EventArgs e)
{
    tell user that procedure 1 begin
    do procedure 1.....
    tell user that procedure 1 finish

    tell user that procedure 2 begin
    do procedure 2.....
    tell user that procedure 2 finish

    etc...
}

protected void ASPxButton_cloture_Click(object sender, EventArgs e)
{
    Response.Write("procedure 1 begin");
    Response.Flush();
    // do procedure 1.....
    Response.Write("procedure 1 finish");
    Response.Flush();

    Response.Write("procedure 2 begin");
    Response.Flush();
    // do procedure 2.....
    Response.Write("procedure 2 finish");
    Response.Flush();

    // ...
}
