How Does ASP.NET Work?
i.When a browser requests an HTML file, the server returns the file.
ii.When a browser requests an ASP.NET file, IIS passes the request to the ASP.NET engine on the server.
iii.The ASP.NET engine reads the file, line by line, and executes the scripts in the file.
iv.Finally, the ASP.NET file is returned to the browser as plain HTML.
Some namespaces used in ASP.NET are:
I.System: This namespace includes the core needs for programming.
II.System.Collections: This defines many common containers and collections used in programming.
III.System.IO: It enables reading from and writing to different streams.
IV.System.Net: It provides an interface.
V.System.Data:It represents the ADO.NET architecture.
VI.System.Web:It provides various web related functionality.
*ASP.NET Controls*
ASP.NET Web server controls are objects on ASP.NET Web pages that run when the page is requested and that render markup to a browser.
Some of ASP.NET Controls are:
i.Button Control: Buttons submit the page to the server and cause it to be processed along with any pending events.
Syntax:
<asp:Button id="Button1"Text="Submit"runat="server"/>
ii.Label Control: The Label Web server control provides a way to display text programmatically control in an ASP.NET Web page.
Syntax:
<asp:Label id="Label1" Text="Label Control" runat="server"/>
iii.Hyperlink: This control displays a link to another Web page.
Syntax:
<asp:HyperLinkid="hyperlink1"ImageUrl="img.jpg"navigateUrl="https://syllabusme.com/search/label/HTML%20language?m=1"text="quizemine"runat="server"/>
iv.ListBox:This control allows users to select one or more items from a pre-defined list.
Syntax:
<asp:ListBox>
<asp:ListItem>Anshul</asp:ListItem>
<asp:ListItem>Himanshu</asp:ListItem>
<asp:ListItem>Nitin</asp:ListItem>
<asp:ListItem>Komal</asp:ListItem>
