What is Kendo UI?

Kendo UI is an HTML5, jQuery-based framework for building modern web apps. Advantages of using Kendo UI

a.       Fast And Responsive

Performance matters. One of the key bottlenecks in modern web development is network latency. The time it takes to make a request to the server and get the results can account for a huge portion of page load time, and with hit-and-miss mobile internet, the problem is magnified. 

With JavaScript development, this is achieved by sending JSON (or sometimes XML) data to the client instead of sending a mix of data and markup HTML. All HTML rendering happens in the browser, keeping communication with the server fast and to a minimum.

b.      Universal Front End Platform

ASP.NET may make certain front-end tasks “drag-and-drop easy,” but it may not be the best platform for raw service performance (too much overhead). Maybe a lightweight NodeJS server would be a better simple, fast service provider.

With a JavaScript/HTML5 front-end, you can test server-side performance and pick the best platform for the task. As long as JSON gets to the browser, your front-end is covered.

How to Select the Tone in Text to Speech Conversion in Windows Forms

Today I am going to explain how we can select tone when we are converting text to speech.

In the previous article Converting Text To Speech in Windows Forms I have demonstrated the way we can get audio output to the typed text in windows forms. Now I’ll demonstrate how we can select the tone that reads the given text.

First drag a combo box onto the form. Then add two values into the combo box i.e. Female and Male.

In the code page write a condition in the button click event. Check which of the following values are selected? The condition can be as follows

if (comboBox1.SelectedItem == "Female")

If the condition is satisfied then the female voice is selected.

Here we will write the Speaker hints as follows

How to clear browser cache in ASP.NET

In this article I will explain How to clear browser cache in ASP.NET?

How to Get All the Weeks into Drop Down list using C# .NET

                                  

Today I am going to explain how we can get all the weeks of a year into Dropdown list using C#.NET

In our application sometimes we may have a requirement to show all the weeks in the dropdown list. We can use C# .NET to get this functionality.

First declare a dropdown list in aspx page as follows

<table>

            <tr>

                <td>

                    <asp:DropDownList ID="ddlWeeks" runat="server" AutoPostBack="true">

                    </asp:DropDownList>

                </td>

            </tr>

        </table>

Now write the code to bind the values in aspx.cs page

First take a method. Here I have declared a method called GetWeeks()

public void GetWeeks()

        {

            try

            {

      }

            catch (Exception ex)

            {

            }

3 tier architecture example in dotnet

In this article I will explain about uses of 3-Tier architecture and how to create and implement 3-tier architecture for our project in asp.net. 

 Uses of 3-Tier Architecture

  

1.    To make application more understandable (Flow of the code). 

2.    Easy to maintain, easy to modify application and we can maintain good look of architecture.

3.    If we use this 3-Tier application we can maintain our application in consistency manner.   

Basically 3-Tier architecture contains 3 layers

1.    Application Layer

2.    Business Logic Layer (BLL) 

3.    Data Access Layer (DAL)

How to set a particular page as Startup page in MVC project?

Today I am going to explain how to set a particular page as Startup page in MVC project.

In normal three tier architecture we will select an aspx page in the solution explorer. Then right click on the page and select set as start page in the menu items.

But in an MVC project we cannot set a page as set as start page.

In order to set that page as a startup page we need to write the code in Global.asax page.

Go to global.asax.cs page.

Create a method called Application_Start() and write the following code

protected void Application_Start()

        {

            AreaRegistration.RegisterAllAreas();

            RegisterGlobalFilters(GlobalFilters.Filters);

            RegisterRoutes(RouteTable.Routes);

        }

Now in RegisterRoutes method add the path info to the page.

public static void RegisterRoutes(RouteCollection routes)

        {

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapHttpRoute(

                name: "DefaultApi",

                routeTemplate: "api/{controller}/{id}",

                defaults: new { id = RouteParameter.Optional }

            );

What is Early Binding and Late Binding in C#.NET and what is the Difference between Early Binding and Late Binding

In this article I will explain what is Early Binding and Late Binding in C#.NET and what is the Difference between Early Binding and Late Binding.

Polymorphism:

An operation may exhibit different behaviours in different instances.Polymorphism means same operation may behave differently on different classes.The behaviour depends on the data types used in the operation.

Polymorphism is extensively used in implementing Inheritance.

 In Polymorphism we have 2 different types those are

       -  Early Binding

       -  Late Binding

What is C#.NET?

In this article i will explain what is C#.NET?
         
            C# (pronounced "C-sharp") is an object-oriented programming language from Microsoft that aims to combine the computing power of C++ with the programming ease of Visual Basic. C# is based on C++ and contains features similar to those of Java.

            C# is designed to work with Microsoft's .Net platform. Microsoft's aim is to facilitate the exchange of information and services over the Web, and to enable developers to build highly portable applications. C# simplifies programming through its use of Extensible Markup Language (XML) and Simple Object Access Protocol (SOAP) which allow access to a programming object or method without requiring the programmer to write additional code for each step. Because programmers can build on existing code, rather than repeatedly duplicating it, C# is expected to make it faster and less expensive to get new products and services to market.
