Linq Query

On 22:44:00 By RAMASHANKER VERMA // No comments:

Language-Integrated Query(Ling) was Introduced as a new Component of .NET Framework 3.0. The basic
function of Linq is to add native data querying capabilities to .Net Framework by using the syntax similar to Structured Query Language(sql).

Linq is a programming model that is used to provide a consistent method to obtain and manipulate
data. Linq define the set of query operators,which are used to query and filter the data.
In .NET Framework 4.0,Linq is used for writing efficient and multithreading queries,which is called
PLinq (Parallel Linq).we can easily retrieve data from various data source through Linq query,
such as Linq to Object,Linq to ADO.NET and Linq to XML.
A query is an expression that retrieves the requested data from a data source .Linq queries
can also perform additional functions.such as sorting and grouping the retrieve data. The various clauses that you can use with the Linq query are the 'Form',where 'order by' and 'Select' clauses.

There are three basic steps to execute the Linq query.

Obtain the data source that can be either an Sql Database or an XML File.
Create the query.
Execute the Linq Query.

Constructor and Destructor In C#

On 20:38:00 By RAMASHANKER VERMA // No comments:

We know that all objects that are created must be given initial values.we have used two approach to initialize the value of all the variables without constructors.

The first approach uses the dot operator to access instance variables and then assigns values to them individually. It can be a tedious approach to initialize all the variables of all the objects.
The second approach takes the help of a function like 'GetData' to initialize each object individually using statement like;

rect1.GetData(30,20);

We can predefine the method of parent class in child class by implementing the concept of method hiding. In method hiding the base(parent) class method is predefined in child class by specify new keyword.
Example:-

Method Overriding in C#

On 11:28:00 By RAMASHANKER VERMA // 2 comments:

When one class inherit from another class ,all the member of parent class become the member of child class .If there is a method of parent class that we want to predefined in child class. we can implement the concept of method overriding ,it means a method overriding of parents class and child class can have same method name with same parameter but parent class method will have "VIRTUAL"Keyword and child class method have "OVERRIDE"Keyword.

Method Overloading in C#

On 00:19:00 By RAMASHANKER VERMA // 2 comments:

We can used more than one Method with same name,within same class but with different parameter,that is called method overloading. When the basic functionality of more than one method is same but they are used different parameter,then we can implement method overloading.
Method overloading will be possible if method name is same but there signature is different.

What is XML and how it differ from HTML

On 21:18:00 By RAMASHANKER VERMA // 2 comments:

XML:-> It is a markup language which is used to describe the data and transfer the data from one application to another application .XML is a language which is platform independent format so it can used on Internet "Heterogeneous environment" to transfer the data and to describe the data.
Difference between XML and HTML:-
XML and HTML both are markup language but there are some difference between HTML and XML.

HTML is used to design the layout of form but XML is used to describe and transfer the data.
HTML is not case sensitive but XML is case sensitive.
HTML has predefined element but XML has not predefined elements. we can specify according to our requirements.

Rules for a Well form Document:-

It must contain a root element.
Every starting tag must be contain end tag.

EX:- <id> ....<//id>

We have to type of elements.

Container element:- In this 'Start tag' will have an 'End tag'.

EX:- <Name>.......</Name>

2. Empty element:- In this 'Start tag' is not 'End tag' but we specify by forwards lace (/).

EX:- <Sid = "100" / >

We can specify an information as an Element or as a Attribute. Attribute value must be enclosed within this " "..

EX:-

Here "101" is attribute value

<Id> 102 </Id>

Here 102 is a value.

Ajax In ASP.NET

On 04:00:00 By RAMASHANKER VERMA // No comments:

Ajax is neither a new programming language nor a new platform for developing websites. Ajax is a new technology which is used to displays the refreshed content on a web page by using the page update approach rather than page replacement approach.
Ajax is built using various technologies which are us follows:-

Java Script:-

Java Script is a client side dynamic scripting language that supports object-oriented programming.It provides various tools, such as from elements, to communicate with server.

X HTML:-

X HTML is a combination of HTML and XML.X HTML is used with Ajax enabled website to ensure that the website runs consistently on all Browsers(IE, Firefox,Chrome, Opera mini).

CSS (Cascading style sheet):-

CSS is a file that define the pattern of a web form.Using CSS, you can specify fonts,colours, styles(bold,italic) and size of controls.It is used to design attractive web page.

DOM (Document Object Model):-

DOM represents a structured web form in an object oriented model. It is a platform and language -independent interface that allows programs and scripts to access and update the content of web form.DOM is recommended by world wide web consortium(w3c) to manipulate content at run time.

XMLHttpRequest Object:-

The core of Ajax functionality is the XMLHttRequest object, as it is responsible for making asynchronous requests to a server,updating the server response and performing necessary changes in the current web page. It sends and receives data in the form of XML.

Ajax Server or Extension Controls:-

Script Manager:-

Script Manager Controls helps in implementing the Ajax functionality in an asp.net website. You need to add this control on a web page whenever Ajax functionality is required. It manage all the Ajax control on the web page. If we are using Ajax control over web page then we first drag and drop this control on the web page.

ScriptManagerProxy Control:-

In any Ajax enabled website is only one Script Manager Control,which manage all the Ajax server controls on that page. If the website contains a 'Master Page'and the Script Manager Control is added in the Master Page. Then all the web page inherited from the Master Page.For this purpose each content page requires a link to connect to Master Page's Script Manager Control.The content page uses the the Script Manager proxy control to make a link with master page.

EX:- If the service and scripts added earlier in the Script Manager Control of the Master Page are not useful for your current web page, then you can remove them by using the Script Manager Proxy Control.

UpdatePanel Control:-

The UpdatePnael Control helps to divide your web page into parts, where each part can be update independently. If we have a button on the web page, which clicking the page goes to the server and back to the client ,if we want to go only a small part of web page to the server then we use the UpdatePanel Control.

Creating a simple Application:-

Drag and drop ScriptManager control,UpdatPanel control , a button control and two label controls from the Toolbox on the Design view of the Default.aspx page.

Set the Text property of the Label1 control s to simple Application with AJAX ,the Button1 control to Display and ID property to Btndisplay.

->On Btndisplay Double click:-

protected void Btndisplay_Click(object sender, EventArgs e)
    {
        String myDateTime;
        myDateTime = System.DateTime.Today.ToLongDateString() + " ";
        myDateTime += System.DateTime.Now.ToLongTimeString();
        TimeLabel.Text = myDateTime;
    }

OUTPUT:-

Application Using Timer Control:-

The Timer control can be used in the following two ways:-

Inside the Update Panel Control
Outside the Update Panel Control

Here we are showing Timer control Inside the Update Panel Control.Outside the Update Panel Control is similar to this .You Can download whole Application from the below download link.

Drag and drop a Script Manager control, Update Panel control,Timer control and two Label controls from the Toolbox on the Design view of the Default2.aspx page.To use Timer control inside the Update Panel control.

Set the Text property of the Label1 control to Application using Timer control,Label2 control to current System time,D property of the Label1 control to Label Heading, ID property of the Label2 control to Time Label,ID property of the Timer control to Timer Updater, and Interval property to 1000

Double click on Timer -Time Updater control:

protected void TimeUpdater_Tick(object sender, EventArgs e)
    {
        TimeLabel.Text = System.DateTime.Now.ToLongTimeString();
    }

OUTPUT:-

Your system current time will be displayed.

Application Using Update Progress Control:-`

Using the Update Progress control for single Update Panel Control.
Using the Update Progress control for Multiple Update Panel Control.

Here we are going to show Update Progress control for Multiple Update Panel Control. Here we are using two Update Panel Control.

Design view Defaut4.aspx:-

Code of Defaut4.aspx.cs:-

protected void BtnProgress_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(5000);
 //LabelDemo.Text = "Demonstration on Update Progress Control taken place last time at " + System.DateTime.Now.ToLongTimeString();
        Response.Redirect("default5.aspx");
    }

OUTPUT:-
In this ,you will see that update is in progress and after 5000 interval it go to Default5.aspx.
