Servlet is java technology provided by Oracle that is used to communicate web server and client like web browsers applications. Servlet as technology provides Java an API to facilitate the development of web applications. It is partially implemented by web server vender and by the application programmer. From an application point of view, it is a java class that is created using Servlet API and instantiated by web server to process dynamic request.
Sensitive data from the page and the states of different controls on the page are stored in hidden fields that form the context of that page request.
NET runtime controls the association between a page instance and its state.
NET page is an object of the Page or inherited from it. All the controls on the pages are also objects of the related control class inherited from a parent Control class.
When a page is run, an instance of the object page is created along with all its content controls.
NET page is also a server side file saved with the. It is modular in nature and can be divided into the following core sections: The Page directive defines page-specific attributes used by ASP.
NET page parser and compiler. Page directives specify how the page should be processed, and which assumptions need to be taken about the page.
It allows importing namespaces, loading assemblies, and registering new controls with custom tag names and namespace prefixes. Code Section The code section provides the handlers for the page and control events along with other functions required.
We mentioned that, ASP. NET follows an object model. Now, these objects raise events when some events take place on the user interface, like a user clicks a button or moves the cursor.
The kind of response these events need to reciprocate is coded in the event handler functions. The event handlers are nothing but functions bound to the controls.
The code section or the code behind file provides all these event handler routines, and other functions used by the developer. The page code could be precompiled and deployed in the form of a binary assembly. Page Layout The page layout provides the interface of the page.
The following code snippet provides a sample ASP. NET page explaining Page directives, code section and page layout written in C: Generally it is c: Open the file from the browser to execute it and it generates following result: Instead of typing the code, you can just drag the controls into the design view: The content file is automatically developed.
But this time, the instead of on submitting the form, validations are on field level, i.e. whenever you move from one field to another. HTML & CSS Web Development HTML Forms Working with XHTML forms can be somewhat daunting; they not only use some niche HTML elements, but also .
To Write a HTML code is simple.
First you open a text editor like NOTEPAD,Word Pad, MS-word etc and write HTML code and save with ".html" or ".htm" extension. whatever field will be required in your course registration webpage you include inside the.
This article explains about creating a simple registration or signup and login or sign in form using regardbouddhiste.com, c#.net and sqlserver. Follow the steps as described below to create the registration form and login form as shown above.
