Operating mechanism:

c/S (client application) code is executed on the client, just go to the database on the server to access data

b/S (website application) program code executes on the server, the client only renders HTML+CSS, executes the JS code, all other functions are executed on the server

The client browser sends the request → IIS (Internet Information Services Manager) on the server (HTML+CSS+JS) →. NET framwork on the server for code processing → databases on the server

Why the web is becoming more and more popular

2, no need to install, anytime and anywhere access to the Web

3. Cross-platform

Second, Repeater control

1. <%@%>-There are some statements and references in this

<%%>-writing C # code

<%=%>-Outputs the value of a variable to the interface

<%# Eval ("attribute name", "optional, format string")%>-used in repeater data presentation

<% #Eval ("Birthday", "{0:yyyy mm month DD day}")%>

<HeaderTemplate></HeaderTemplate> perform first, once, often to show the table header

<ItemTemplate></ItemTemplate> executes after <HeaderTemplate></HeaderTemplate> to bind the data, how many times the data is executed.

<AlternatingItemTemplate></AlternatingItemTemplate> alternating item templates, with <itemtemplate></itemtemplate > Alternate execution.

<FooterTemplate></FooterTemplate> last executed, executed once

3. Data binding
