ASP.Net Web Server Control
 
ASP.NET Web Server Controls
 
Web controls are alike to the HTML server controls such as TextBox, Button, and Hyperlink, except that Web controls have a standardized set of property names. Similar to HTML server controls, Web server controls are also created on the server and they need a runat="server" attribute to work. Web server controls are implemented using particular ASP.NET tags understood by the server.
 
The syntax for creating a Web server control is:
 
<asp:control_type id="control_id" runat="server" />
