Iframe implements brushless newest Linkage

The refreshing of iframe is actually a partial refresh. the scroll bar of the status bar will still scroll, but the page will not flash. This is an old technology, the processing data is slow. In this example, two pages are required: index. aspx and frame. asretrial, index. aspx is used to display the interface, with an iframe mark pointing to frame. the aspx page is used to display results.
Index. aspx front-end code

<% @ Page Language = "C #" AutoEventWireup = "true" CodeFile = "Index. aspx. cs" Inherits = "_ Default" %> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
Front-end code of frame. aspx:
<% @ Page Language = "C #" AutoEventWireup = "true" CodeFile = "frame. aspx. cs" Inherits = "myframe" %> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
Frame. aspx background code:

JavaScript refreshing

<% @ Page Language = "C #" AutoEventWireup = "true" CodeFile = "index. aspx. cs" Inherits = "callback_Default" %> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

UI. page, ICallbackEventHandler {private string _ data; protected void Page_Load (object sender, EventArgs e) {} ICallbackEventHandler member}
Ajax refreshing

This example also uses two pages: oec203index. aspx and datapage. aspx. datapage. aspx, which are mainly used to send data to be displayed.
. Aspx page front-end code:
<% @ Page Language = "C #" AutoEventWireup = "true" CodeFile = "index. aspx. cs" Inherits = "ajax_Default" %> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
Datapage. aspx background code:
