NET is a web development platform, which provides a programming model, a comprehensive software infrastructure and various services required to build up robust web applications for PC, as well as mobile devices. NET works on top of the HTTP protocol, and uses the HTTP commands and policies to set a browser-to-server bilateral communication and cooperation. All client side user activities are forwarded to the server for stateful processing. NET framework helps in storing the information regarding the state of the application, which consists of: The page state is the state of the client, i.e., the content of various input fields in the web form. Click the button to see effect: We have studied the page life cycle and how a page contains various controls. The page class has the following extremely useful properties that correspond to intrinsic objects: We will discuss each of these objects in due time. However, this object helps in checking some information such as the client browser and cookies. The content file: Run the page to see the following result: Controls are small building blocks of the graphical user interface, which include text boxes, buttons, check boxes, list boxes, labels, and numerous other tools. Net server controls inherit all properties, events, and methods of the Web Control and System. Other Navigation controls are: Menu control and Site Map Path control. Write a few lines of code to ensure that when a particular node is selected, the label control displays the node text and the text box displays all child nodes under it, if any. If more than one group is required in a single form, then specify a different group name for each group. The browser submits a web form to the web server and the server returns a full markup page or HTML page in response. The label shows page load, page initialization and, the page pre-render events. The methods and properties of the Http Server Utility class are exposed through the intrinsic Server object provided by ASP. The following table provides a list of the properties: The request object is an instance of the System. The information presented by this object is wrapped by the higher level abstractions (the web control model). However, the Http Response object still provides some important functionalities, like the cookie feature and the Redirect() method. Redirect() method allows transferring the user to another page, inside as well as outside the application. The following table provides some noteworthy properties of the Response object: The following simple example has a text box control where the user can enter name, a button to send the information to the server, and a label control to display the URL of the client computer. A Tree view control comes under navigation controls. task allows you to format the tree view as shown: Add a label control and a text box control on the page and name them lblmessage and txtmessage respectively. To create a group of radio buttons, you specify the same name for the Group Name attribute of each radio button in the group. Text = "You must select a room type." End If End If End If The error I keep getting is "expression expected" at the end of the two andalsos. Been racking my brain with this, scouring the internet, & both of my textbooks, & have even ordered an "ASP. I would appreciate any pointers anyone could give me.
