Asp.net is the Web branch of. NET Framework .. Net Framework is completely originated from the hierarchical structure of object-oriented classes, covering all Programming Problems in the Windows operating system. Web ApplicationsProgramConsists of pages, the user requests these pages from the server, and then the server processes the page, with HTMLCode. The method for processing the requested resource varies with the server. If the resource has a. aspx extension, IIS delegates the Asp.net Runtime library system for processing.
The. ASPX page where the Asp.net Runtime Library will be requestedSource codeConvert to an instance of the. NET Framework class inherited from the page base class. In short, the running Asp.net page is an object, and some components (that is, server-side controls) are also objects.

Any element can be identified by ID and written for it. All the elements on the page are real components, not just parsed texts. This model is flexible and powerful in scalability.

Runat is available in: 1. Server Control:
(System.web.ui.html controls and System. Web. UI. webcontrols)
Ii. full-page mark:
<Title>, <link>, <body>, <span>, <div>, <font>, and <IFRAME> for example:
<Title ID = "thetitle" runat = "server"/>
<Body id = "thebody" runat = "server"/>
<SCRIPT runat = "server">
Void page_load (Object sender, eventargs e ){
Thetitle. innertext = "Pro Asp.net (CH 01 )";
Thebody. attributes ["bgcolor"] = "yellow ";
}
</SCRIPT>
Iii. meta tag:

<Meta id = "meta1" runat = "server" http-equiv = "refresh"/>
<SCRIPT runat = "server">
Void page_load (Object sender, eventargs e ){
Meta1.attributes ["content"] = "4; url = http://www.asp.net ";
}
</SCRIPT>
Generation: <meta id = "meta1" http-equiv = "refresh" content = "4; url = http://www.asp.net"> </meta>

<SCRIPT runat = "server">
Void page_load (Object sender, eventargs e ){
