i am a beginner 

```

function PopupUserRegist() {

        result = $.ajax({ url: "Default.aspx?cmd=Setting",
            async: false ,
            complete: function () {
                // unblock when remote call returns 

            }
        }).responseText; ;

   }

```

```

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request["cmd"] == "Setting")
        {
              div.InnerText = "test"; //This  does not change inner text 
        }
    }

```

```

    protected void Button2_Click(object sender, EventArgs e)
    {
        div.InnerText = "test";//This   change inner text
    }

```
