Types,Modes,Differences of session in

Overview of session modes and types in

Normally http protocol is stateless to maintain state following namespace is used.


Modes And's Provider:

Session State Mode State Provider

InProc In-Memory Object
StateServer Aspnet_state.exe
SQLServer DataBase
Custom CustomProvider

Session Event's:

There are two types of session events available in

* Session_Start
* Session_End


1.inproc Mode (ie inprocess)--->Its availble inside the webserver itself not ouside the application.
2.StateserverMode(ie out process) -->Its availble outside the webserver,not inside the application.
3.sqlserver Mode -->To store session datas in sqlserver.AND DATAS CAN BE SHARED BETWEEN OTHE APPLICATIONS.
4.Custom Mode --> To create a manual session id's.

1.inproc Mode

Advantages :

* It store Session data in memory object of current application domain. So accessing data is very fast and data is

easily available.
*Datas not alive when application restarted.
* There is not requirements of serialization to store data in InProc Session Mode.
* Implementation is very easy, just similar to using View State.


If the worker Process or application domain recycles all session data will be lost.


This session state is totally managed by aspnet_state.exe.

This approaches has several disadvantages due to the overhead of serialization and de-serialization.

Datas will be alive it the aspnet services restarted also.

3.sqlserver Mode

The most easiest way to configure SQL Server, is using aspnet_regsql command.

4.Custom Mode --> To create a manual session id's.

Differences::::Div vs span vs iframe

Differences::::Div vs span vs iframe

Blogger wont allow HTML content you can get full article which is given below from this link.You can download it..

DIV is short for "division" because it divides elements.

span is inline, div a block.span is permitted in a div, but not div in a span.

The main difference is that span element is in-line and usually used for a small chunk of in-line HTML whereas a div (division) element is block-line (which is basically equivalent to having a line-break before and after it) and used to group larger chunks of code.

is a block level element -- it's going to 100% width, and it will line break - and is best used for structure (stands for 'division' -- semantic markup here!)
is inline, it can go next to other elements and is best used for text editing... adding rules to special text in a paragraph, hiding text (like navigation), etc.


The div tag has forced a line break.
The div tag will force a line break.
The div tag has forced a line break.The span tag does not force a line break. There is no line break.

Reference to div tag properties::::

IFrame and Div are HTML tags. They are only for the layout purposes. Using IFrame, you can view another html file in your main html.
Div is used to display contents in a html page. You can put some text,image, and/or combination to display in a div.

An iframe is like having a hole on your page, and in that hole is another web page. If that page is clicked ONLY that page will refresh so that the rest of the site appears to stay in the same place. It's not valid HTML and is therefore not encouraged because browsers can interpret iframes however they want. An iframe is only a container and the page that goes inside it still needs to be written as usual.

To get small idea to get what is div tag

#framearea {
width: 550px;
height: 150px;
margin-bottom: 10px;
.framebody {
overflow: auto;
width: 550px;
height: 150px;

...content here...

Using a DIV as variable to write into IFRAME

Difference between Repeater , Datalist, DataGrid(or GridView)

Difference between Repeater , Datalist, DataGrid(or GridView)

Repeater :

It contains Header Template, Item template , alternate
Item template and footer template . it can't support
Selection, editing, sorting and paging. this is read only
and fast.

Datalist :

It contains Header Template, Item template , alternate
Item template , Edit itm template and footer template . it
can't support sorting and paging but support selection and

DataGrid(or GridView) :

It contains Header Template, Item template , alternate Item
template , Edit itm template and footer template . it can
support selection, editing , sorting and paging . Mostly
every developer caught used this control.

Datagrid vs Gridview

In datagrid you cannot set a permisiion level........

In gridview you can do the access level............

GridView is a composite data-bound control and shares a common set of methods and properties with all other data-bound controls, including DropDownList, DetailsView, and ListBox.

GridView can render on mobile devices.

Grid view Control take care automatically deletes or updates records from the datasource.

SilverLight 3.0 Features.

Silverlight 3.0 Features:

1.SLOOB(SilverLight out of browser).

Its like a java Applet(Application embedded into browser).but in silverlight we can get that application out of browser and we can use it and access/modify it.After finishing your work you can update it.

We can download that Apllication into your local system by the following ways,

A, Context Menu(By right clicking the app in the browser u can install it in your local system.

B, By the Button click event(Here you can write your program for the installation of Browser App).

There are two main events (Trigger and Network Event)

Network Event:

When you are working in your App(online) if suddenly your connection disconnected it will gives status as its disconnected its done through coding.

Trigger Event:

When you are working in your App(offline) you can update ur app at anytime from the main app(online).By placing the button like install.


The files or datas what you are working with offline app it wont affect your local system other drives such as c:,d:,etc.....It's mean SECURITY.

It allot separate space for his work that place is ISOLATED STORAGE.

Default size of isolated storage 25MB. But it can extended to what ever size(UNLIMITED).

Difference between DotNet 1.0,2.0,3.0,4.0

DotNet 1.0 = Managed code.
DotNet 2.0 = Generics,ADO.NET.
DotNet 3.0 = Linq(Language Integarated Query),Partial Methods, VAR Keyword.
DotNet 4.0 = Dyanamic Programming.

DotNet 1.0 Understand It:

.Net managed code enjoy's benefits of CLR, which automatically checks for object scope and if it is not referenced by any object than it is removed from memory.

What is the difference between managed and unmanaged code?

Program written in any .net compatible language will go for
compilation for 2times.
In the first compilation of the program, the language
compiler will generate MSIL code which is the managed code. &

the code generated after the second execution ie by the CLR
is called unmanaged code which is machine understandable and
not by the user.

What is MSIL code ?

When the code is compiled, the compiler translates your code
into Microsoft intermediate language (MSIL). The common
language runtime includes a JIT compiler for converting this
MSIL then to native code.
MSIL contains metadata that is the key to cross language
interoperability. Since this metadata is standardized across
all .NET languages, a program written in one language can
understand the metadata and execute code, written in a
different language. MSIL includes instructions for loading,
storing, initializing, and calling methods on objects, as
well as instructions for arithmetic and logical operations,
control flow, direct memory access, exception handling, and
other operations.

DotNet 2.0: Generics,ASP.NET-AJAX.

DotNet 3.0: Understand It:

1.1-->Partial Methods(Refer:

1.2-->LINQ stands for Language-Integrated Query. This means we can use any relational or XML-specific features to our programming languages and runtime. It is a general approach query and provide facilities to the .NET Framework to access any kind of sources of information, not just relational or XML data. It's a Language-Integrated Query to indicate that query is an integrated feature of the developer's primary programming languages (for example, Visual C#, Visual Basic). Language-integrated query allows query expressions to benefit from the rich metadata, compile-time syntax checking, static typing and IntelliSense that was previously available only to imperative code.

The format of the query is more or less simillar to that of SQL. The Select, From, Where clauses are also used here with the same meaning but in different style/location/position. Here is an example of a LINQ program.

using System;
using System.Linq;

class sample
static void Main()
int[] arrMarks = {78, 90, 56, 45, 89, 23, 67, 93};

IEnumerable Distinction = from m in arrMarks
where m > 70
orderby m
select m;

foreach (int distMark in Distinction)

DotNet 3.5 Understand It:

WPF = Windows Presentation Foundation.

WPF is the latest in desktop app development in .Net. It features markup based layout much like The markup language is XAML. It provides a new way to develop desktop applications keeping UI and logic separate.

WCF = Window Communication Services

WCF is used to communicate between different applications with stuff like services. It is much like web services, but is much more robust and configuration enabled. WCF web services can be configured to act like asmx webservices, or use json or something else. Anything that represents a service can benefit from WCF, such as web services, windows services etc.

DotNet 4.0: Dyanamic Progamming

1.Named and Optional Parameters.(Refer:::
2.Integarated COM interop.
3.Co and Contra Variance(Used in interface and delegates).
4.Dyanamic Typed Objects.
5. Response.PermanentRedirect,Page.Keywords and Page.Description Properties for SEO

Example For Dyanamic Keyword:

It's one of way to tranfer datas or values from one aspx page to another.Before knowing query string u should know GET method and POST method.
In Get method u can transfer a values but its limited about 256 characters and u can view it in the address bar example:
In post method its unlimited values transering so better choose POST method in a form tag.
From the address bar url we get values to the another page.

Application State:

It's one of way to tranfer datas or values from one aspx page to another.But the state or values in the memory were stayed till open -(to) close the application.Application in the sense for eg; Browsers.


It's one of way to tranfer datas or values from one aspx page to another.cookies means a small data ie key value pairs were stored in our local systems and it has been accessed by all other aspx pages.But its not good practice because some of systems ie browsers has not support the function of cookies.Because it were disabled.

Session State:

It's one of way to tranfer datas or values from one aspx page to another.When we talk about session there are many types.But basically means maintaning the state of the user. Example:when user logged into certain site for shopping till he log out the id for him is provided automatically intially..By that id we can track the user and maintain his state till logout.
