HTML Server Controls
HTMLserver controls are simple HTML tags with a runat="server"attribute,which enables developers to access them programmatically and work with them in a similar way to Web controls.So,why include these types of controls when we have Web controls?Well,HTMLserver controls do havesome advantages over Web controls,including:
1.Web developers coming from an ASP3 or similar background may prefer to work with the HTML-style of control that they're used to
2.Developers can convert existing HTMLtags to HTMLserver controls fairly easily,thus gaining some server-side programmatic access to the control When a runat="server" attribute is added to an HTMLtag,the tag becomes a control.Each of these controls derives its functionality from the System.Web.UI.HtmlControls.HtmlControl base class.
Like Web controls,HTMLserver controls offer a variety of features that include:
1.Programmatic object model：
HTMLserver controls can be accessed programmatically on theserver.Each HTMLserver control is an object and you can access its various properties and get(and /set) them in your method or event-handler code.
2.Event processing：
HTMLserver controls provide a mechanism to write event handlers in muchthe same way as you would for a client-based form.The only difference is that the event is handled in the server code.
3.Automatic value caching：
When form data is posted to the server,the values that the user entersinto the HTMLserver controls are automatically maintained when the page is sent back to the browser.The magic behind this functionality is the result of a property called ViewState that all ASP.NET Web controls inherit.
