Authorization Concept in .net

Authorization Concept in .net

Introduction:

            In this article we going to know about the authorization concept in .net.
Authorization is a process of allowing or denying resources to the users.

To know more about checkout the example, I have used VS2008.

Step 1: create a website and on the solution explorer check the web.config file

Step 2:(For Application)
Now change the authentication mode to Forms" to apply the authorization concept, and also add authorization in system.web section to allow or deny users.

This will be used only for creating an application and give permission to some users to use like office use.

But at the same time if I have a website and need users to see registration webpage and other web page if they logged in, then we have to use the below code

Step 3:(For webpage)
     

 Still now we have seen how to allow authenticated users, now we going to see how to allow particular users

Step 4:(To allow particular users for application)

This will allow only 'ramanand" and restrict others.

Step 5:(To allow particular users for website)
    

As of now we have seen allow or deny anonymous users, now we going to learn how to apply this authorization concept for various roles users like admin

here,
I have two folders one is Administrator folder and another one is Customer folder. Now I want give permissions like Admin role users are able to access both the folders and Customer role users are able to access only Customer folder for that we need to set the condition like this in web.config file.

In this way we can use the authorization concept in asp.net and also note that before use deny we have to use allow tag!

ASP PAGE LIFE CYCLE

ASP PAGE LIFE CYCLE

Introduction:

     The life cycle of an asp.net page can be understandable easily if you have a knowledge of some keywords like viewstate, postback and events in asp.net . 

Description:

PreInit -

* In preinit you can check weather the page is loaded first time             or  not using IsPostBack property.
* On the first time load page you can create control with values.
* You can set master page and theme dynamically.

* If the page is postback, you can set control property value to           be overwritten. 
 * The values have not been yet restored from viewstate.
     
Init -

* In the Init event of the individual controls occurs first, later               the Init event of the Page takes place.
 * This event is used to initialize control properties.

InitComplete -

* In the InitComplete event the viewstate property checking will be done and that changes will be persisted until next postback.

PreLoad -
* This will process the data on postback event with the request.

Load -
* In this process the initial Page controls or objects calls the OnLoad method and that method with any controls or objects comes next.

ControlEvents -

* This events occurs after page loads like onclick in button, textchanged in textbox, onchange in dropdownlist etc.

In case of the postback, 
if the page contains validator controls , the page.isvalid property and the validation of the control takes place before the firing of individual events.

Load Complete - 

* This session occurs after the event handling page.
* This will complete all controls and their methos events.

Pre Render -

* This method is used to make final changes to the controls on the page like assigning the DataSourceId and calling the DataBind method.

PreRenderComplete -

* This event is raised after all the final id values are set in prerender completes.

SaveStateComplete -

* This will occur after control state and view state saved.

RenderComplete -

* This method writes the controls values or markup to the browser.

Unload -

* This event is raised for each control and then for the page.

* This will do the final clean up work and close dataconnection etc.,

If any clarification or need changes please comment.

Overloading and Overriding in C#

Overriding and Overloading in C#

Hi, today we going to learn all about the overloading and overriding concepts in c# with example.

Description:

Before going to the overloading and overriding, we have to learn polymorphism, which is the one of the important concept of oops.

Poly means 'many' , morph means 'forms' hence, hence the polymorphism means ability to take many forms.

In polymorphism we can declare the same method name with different arguments in a class and same method name with same arguments in different classes. The polymorphism has the ability to provide different method implementation and that are with the same name.

We have two types of polymorphism, namely

Overloading and Overriding 

Overloading:

In overloading the same name with different signature can be used, thus provides us the benefit of using same name with different tasks. This is also called as compile time polymorphism .

Overriding:

In overriding the method name have same signature can be used in many class with the reference, hence at the runtime only the method and its signatures will be known to the clr.
This is also known as runtime polymorphism.

Overriding an be performed using virtual and override keywords.

Initially we need to create a method with the name virtual and when using the same method name we have to use override keyword.

*signature = parameters

example of overloading:

Example of overriding:
