What is ASP.NET?
|
|
ASP.NET is a server side scripting
technology that enables scripts (embedded in web pages) to be executed by an
Internet server.
ASP.NET provides increased performance by running compiled code. |
2.
|
What is the difference between Classic
ASP and ASP.Net?
|
|
ASP is
Interpreted language based on scripting languages like Jscript or VBScript.
ASP.Net
is supported by compiler and has compiled language support.
|
3.
|
What is Difference between
Namespace and Assembly?
|
|
Namespace is a logical design-time
naming convenience, whereas an assembly establishes the name scope for types
at run time.
|
4.
|
What is the difference between
early binding and late binding?
|
|
Calling a non-virtual method,
decided at a compile time is known as early binding. Calling a virtual method
(Pure Polymorphism), decided at a runtime is known as late binding.
|
5.
|
What is the difference between ASP
Session State and ASP.Net Session State?
|
|
ASP session state relies on
cookies, Serialize all requests from a client, does not survive process
shutdown, Can not maintained across machines in a Web farm.
|
6.
|
What is the difference between ASP
Session and ASP.NET Session?
|
|
Asp.net session supports cookie
less session & it can span across multiple servers.
|
7.
|
What is reflection?
|
|
All .NET compilers produce
metadata about the types defined in the modules they produce. This metadata
is packaged along with the module (modules in turn are packaged together in
assemblies), and can be accessed by a mechanism called reflection.
The System.Reflection namespace contains classes that can be used to interrogate the types for a module/assembly. |
8.
|
What is the difference between
Server.Transfer and response.Redirect?
|
|
|
The Server.Transfer ()
method stops the current page from executing, and runs the content on the
specified page, when the execution is complete the control is passed back to
the calling page.
While the Response.Redirect () method transfers the control on the specified page and the control is never passed back to calling page after execution. |
|
9.
|
What is a PostBack?
|
|
|
The process in which a Web page
sends data back to the same page on the server.
|
10.
|
What namespace does the Web page
belong in the .NET Framework class hierarchy?
|
|
System.Web.UI.Page
|
11.
|
What’s a bubbled event?
|
|
When you have a complex control,
like DataGrid, writing an event processing routine for each object (cell,
button, row, etc.) is quite tedious. The controls can bubble up their event
handlers, allowing the main DataGrid event handler to take care of its
constituents.
|
12.
|
What is the differences between
Server-side and Client-side code?
|
|
|
13.
|
What is the difference between
static or dynamic assemblies?
|
|
Assemblies can be static or
dynamic.
Static assemblies can include .NET Framework types (interfaces and classes), as well as resources for the assembly (bitmaps, JPEG files, resource files, and so on). Static assemblies are stored on disk in portable executable (PE) files. Dynamic assemblies, which are run directly from memory and are not saved to disk before execution. You can save dynamic assemblies to disk after they have executed. |
14.
|
What are the difference between
Structure and Class?
|
|
|
15.
|
What is the differences between
dataset.clone and dataset.copy?
|
|
Dataset.clone copies just the structure of dataset (including all the
datatables, schemas, relations and constraints.); however it doesn’t copy the
data.
Dataset.copy, copies both the dataset structure and the data. |
16.
|
What is the difference between Custom
Control and User Control?
|
|
Custom Controls are compiled code (Dlls), easier to use, difficult to
create, and can be placed in toolbox. Drag and Drop controls. Attributes can
be set visually at design time. Can be used by Multiple Applications (If Shared
Dlls), Even if Private can copy to bin directory of web application add
reference and use. Normally designed to provide common functionality
independent of consuming Application.
User Controls are similar to those of ASP include files, easy to create, can not be placed in the toolbox and dragged - dropped from it. A User Control is shared among the single application files. |
17.
|
What is the difference between ASP
Session State and ASP.Net Session State?
|
|
ASP session state relies on
cookies, Serialize all requests from a client, does not survive process
shutdown, Can not maintained across machines in a Web farm.
|
18.
|
What is ViewState?
|
|
ViewState is a .Net mechanism to store the posted data among post
backs. ViewState allows the state of objects to be stored in a hidden field
on the page, saved on client side and transported back to server whenever
required.
|
19.
|
What is Authentication and
Authorization?
|
|
Authentication is the process of identifying users. Authentication is
identifying/validating the user against the credentials (username and
password) and Authorization performs after authentication.
Authorization is the process of granting access to those users based on identity. Authorization allowing access of specific resource to user. |

|
|
There are three types of Caching :
|
26.
|
What is Side-by-Side Execution?
|
|
The CLR allows any versions of the
same-shared DLL (shared assembly) to execute at the same time, on the same
system, and even in the same process. This concept is known as side-by-side
execution.
|
27.
|
How to view an assembly?
|
|
We can use the tool
"ildasm.exe" known as "Assembly Disassembler" to view the
assembly.
|
28.
|

|
29.
|
What are the layouts of ASP.NET
Pages?
|
|
.

30.
|
What is Delegates?
|
|
Delegates are a type-safe,
object-oriented implementation of function pointers and are used in many
situations where a component needs to call back to the component that is
using it. Delegates are generally used as basis of events, which allow any
delegate to easily be registered for as event.
|
31.
|
What is a Namespace? What is the
use of a namespace?
|
|
Namespaces are logical grouping of
classes and other types in hierarchical structure.
Namespaces are useful to avoid collision or ambiguity among the classes and type names. Another use of the namespace is to arrange a group of classes for a specific purpose. |
32.
|
What’s the difference between
Codebehind="MyCode.aspx.cs" and Src="MyCode.aspx.cs"?
|
|
Visual Studio uses the Codebehind
attribute to distinguish the page source or programming logic from the
design. Also the src attribute will make the page compile on every request.
That is the page will not be compiled in advance and stored in the bin as a
dll instead it will be compiled at run time.
|
33.
|
What is datagrid?
|
|
The DataGrid Web server control is
a powerful tool for displaying information from a data source. It is easy to
use; you can display editable data in a professional-looking grid by setting
only a few properties. At the same time, the grid has a sophisticated object
model that provides you with great flexibility in how you display the data.
|
34.
|
How do you hide the columns?
|
|
One way to have columns appear
dynamically is to create them at design time, and then to hide or show them
as needed. You can do this by setting a column’s “Visible” property.
|

the data.
where as Reference type uses the Heap to store the data. |
|
41.
|
What is the difference between
Server-side scripting and Client-side scripting?
|
|
|
Server side scripting means that all the script will be executed
by the server and interpreted as needed. ASP doesn't have some of the
functionality like sockets, uploading, etc.
Client side scripting means that the script will be executed immediately in the browser such as form field validation, clock, email validation, etc. Client side scripting is usually done in VBScript or JavaScript. |
42.
|
How do you create a permanent
cookie?
|
|
Permanent cookies are available
until a specified expiration date, and are stored on the hard disk.So Set the
'Expires' property any value greater than DataTime.MinValue with respect to
the current datetime. If u want the cookie which never expires set its
Expires property equal to DateTime.maxValue.

meanings.It includes databa which includes connections,Session States,Error
Handling,Security etc.
|
47.
|
What is the difference between
in-proc and out-of-proc?
|
|
An Inproc is one which runs
in the same process area as that of the client giving tha advantage of speed
but the disadvantage of stability becoz if it crashes it takes the client
application also with it.
Outproc is one which works outside the clients memory thus giving stability to the client, but we have to compromise a bit on speed. |

56.
|
What is strong-typing versus
weak-typing?
|
|
Strong typing implies that the types of variables involved in
operations are associated to the variable, checked at compile-time, and
require explicit conversion
Weak typing implies that they are associated to the value, checked at run-time, and are implicitly converted as required. |
57.
|

|
Implicit conversion of value type
to reference type of a variable is known as BOXING, for example integer to
object type conversion.
Conversion of reference type variable back to value type is called as UnBoxing. |
58.
|
What is garbage collection?

Serialization is the process of
converting an object into a stream of bytes.
Deserialization is the opposite process of creating an object from a stream of bytes. Serialization / Deserialization is mostly used to transport objects. |
60.
|
What is the differnce between
Managed code and unmanaged code?
|
|
Managed Code: Code that runs under a "contract of
cooperation" with the common language runtime. Managed code must supply
the metadata necessary for the runtimeto provide services such as memory
management, cross-language integration, code access security, and automatic
lifetime control of objects. All code based on Microsoft intermediate
language (MSIL) executes as managed code.
Un-Managed Code:Code that is created without regard for the conventions and requirements of the common language runtime. Unmanaged code executes in the common language runtime environment with minimal services (for example, no garbage collection, limited debugging, and so on). |

any value. It's used when you want the control should not be empty.
|
68.
|
What are the different types of
Session state management options available with ASP.NET?
|
|
ASP.NET provides In-Process and
Out-of-Process state management. In-Process stores the session in memory on
the web server. Out-of-Process Session state management stores data in an
external data source. The external data source may be either a SQL Server or
a State Server service. Out-of-Process state management requires that all
objects stored in session are serializable.

What is the difference between an
abstract method & virtual method?
|
|
An Abstract method does not
provide an implementation and forces overriding to the deriving class (unless
the deriving class also an abstract class),
Virtual method has an implementation and leaves an option to override it in the deriving class. Thus Virtual method has an implementation & provides the derived class with the option of overriding it. Abstract method does not provide an implementation & forces the derived class to override the method. |

What is the difference between
Compiler and Interpreter?
|
|
Compiler:
A compiler is a program that translates program (called source code) written in some high level language into object code.A compiler translates high-level instructions directly into machine language and this process is called compiling. Interpreter: An interpreter translates high-level instructions into an intermediate form, which it then executes. Interpreter analyzes and executes each line of source code in succession, without looking at the entire program; the advantage of interpreters is that they can execute a program immediately |

Data List, and Repeater can have other child controls inside them. Example
Data Grid can have combo box inside data grid. These child control do not
raise there events by themselves, rather they pass the event to the container
parent (which can be a data grid, data list, repeater), which passed to the
page as “ItemCommand” event. As the child control send events to parent it is
termed as event bubbling.
