New features in Visual Studio 2013 Developers perspective

    Hello All this is my third Article in this blog.Although main Objective of this Blog is to provide set of Online Quizzes and MCQs on Microsoft Technologies & Basics of Computers but after successful response to my Article- CRUD operation using Entity Framework and LINQ
some of my friends suggested me write few more articles and I am happy for that ☺☺☺.
This post is all about new features in Visual Studio 2013 IDE which I like most, We are happy for how Microsoft is managing the excellency in products like .NET Framework,Visual Studio,Windows and many more.
Visual Studio 2013 has new and enhanced features like,
1)Visual Studio languages      2).NET Framework 4.5.1
3)TFS and ALM                   4)SharePoint and Office
5)LightSwitch                        6)Windows Azure Mobile Services etc.etc. but in this post I am not going to discuss all the above.
Here we are going to discuss about Developers perspective of Visual studio 2013 for innovative features for greater productivity,
Following features which I like the most ☺☺☺...
1)Peek Definition(Alt+F12)
2)Move Code Line Up/Down (Alt+Arrow)
3)Inline Navigate To OR Code Lens(Ctrl+,)
4)64bit Edit and Continue
5)Back to Origin (i.e. icon colors)
Features like TFS&ALM(Team Foundation Server & Application Lifecycle Management)are fabulous in VS2013 as they made Developers or Support Team's life very easy for managing applications from Development phase till production deployment.
VS2013 also helps in Agile Portfolio Management for the Projects which are following Agile/Srum methodology of development.
So lets start with our favorite features ☺,
1)Peek Definition:
While coding most of developers are unhappy with F12(Go TO Definition) as after continuous clicking F12 they are getting lost from where they started or what they want actualy :P ,but that problem is getting resolved in this new IDE VS2013 ☺, now we can see the definition on the same file with new window as follow,

2)Move Code Line Up/Down:
This is very cool feature added in VS2013,with key (Alt+Arrow) we can move code segment Up or Down with arrow keys.
It will really help in performance improvement for Developers.
3)Inline Navigate To OR Code Lens:
Using this feature (ALT + ,) we can easily check the history of file as it is directly synched with TFS,so this feature can check who worked on this file by checking changeset.We can also check test cases passed/failed for particular code snippet.

This feature is helpful for Developers to find References,Find history and also in UTC executions.

4)64bit Edit and Continue:
It enables you to make changes to your source code while your program is in break mode but previous IDE were throwing exceptions for 64 bit,but now VS2013 IDE enables Edit and Continue for 64-bit and support for asynchronous debugging.

5)Back to Origin:
This is last but very important feature I like as all of us were complaining about Color and Themes of VS2012.
This new IDE is having good themeing functionality and decent color schemes ☺,here we can see light color icons compare to VS2012.
Here I have listed some cool features which I like most but you can find many new features added in VS2013 which are helpful in developers productivity.
Conclusion:
In this article we have seen some cool features of Visual Studio 2013 which helps in improvement of Developers productivity. I hope this post will help you.
Happy Development!!!☺☺☺

You receive the following error message when the Index method is invoked: "The view 'Index' or its master was not found." You need to resolve the error so that the new view is displayed when the Index method is invoked.What should you do? Create a folder named Cart inside the Views folder.Move Index.aspx to the Cart folder. Modify the Index method by changing its signature to the following: public ActionResult Index(Cart c) Change the name of Index.aspx file to Cart.aspx None of above 5.You are developing an ASP.NET MVC 2 application. A view contains a form that allows users to submit their first name. You need to display the value that is submitted, and you must ensure that your code avoids crosssite scripting. Which code segment should you use? <% Response.Write(HttpUtility.HtmlDecode(Model.FirstName)) %> <%: Model.FirstName %> <%= Model.FirstName %> Both b&c will work 6.Which of the following statement is false about MVC in .NET? Complete control over your HTML Markup Makes Test Driven Development (TDD) very difficult Allows you to create SEO-friendly URLs for your site Enables rich AJAX and jQuery integration 7.The Controller class is responsible for the following processing stages: Locating the appropriate action method to call and validating that it can be called. Getting the values to use as the action method's arguments. Handling all errors that might occur during the execution of the action method. All of the above. 8.Which Helper Method is used to return a user-defined content type. Content JavaScript View RedirectToRoute 9.Which Helper Method Returns binary output to write to the response?

Online Quiz on State Management in ASP.NET

While working in WEB Envrionment with HTTP Protocol it becomes challenging to manage state of web applications as HTTP is stateless protocol. But,State management techniques in ASP.NET are used to maintain user state throughout the application. State management becomes essential while learning WEB Application development,let's have look on how many techniques are there to achieve this,
Main techniques are,
a.Client Side
b.Server Side
c.SQL Server State Management

Client Side State Management Techniques:

1. ViewState
2. Hidden fields
3. Query strings
4. Cookies
5. Control state</>

Server Side State Management Techniques:

1. Application State
2. Session State
3. Profile Properties
4. Database support

In this post I am not going to explain above techniquies in detail rather than I am writing Quiz for above topic to test your knowledge about that.Now you might be thinking that how we will test programming knowledge with Quiz,I know we can test our programming knowledge while actual development/work but we should be aware of the topic what we are going to implement,what is syntax?Is there any impact of your implementation on existing application?what will be performance impact?

So,let's take this simple quiz... ☻☻☻

CRUD operation using Entity Framework and LINQ

This article is for beginners who are new to EF Terminology and currently working on ADO.NET by creating DAL,BAL to interact with database.
First question comes in to picture is What is Entity Framework?
Lets see the definition given by Microsoft-"The Microsoft ADO.NET Entity Framework is an Object/Relational Mapping (ORM) framework that enables developers to work with relational data as domain-specific objects, eliminating the need for most of the data access plumbing code that developers usually need to write. Using the Entity Framework, developers issue queries using LINQ, then retrieve and manipulate data as strongly typed objects. The Entity Framework’s ORM implementation provides services like change tracking, identity resolution, lazy loading, and query translation so that developers can focus on their application-specific business logic rather than the data access fundamentals."
So,Entity Framework is ORM(Object/Relational Mapping) framework.
ORM helps to keep database design separate from domain Class design and it also improves standard CRUD (Create, Read, Update & Delete)operation.
Entity Framework 4.1 have multiple modeling techniques like code first, model first or database first.Here we are going to implement Database first approach. In this article we are also going to implement LINQ(Language Integrated Query)to perform CRUD operation with entity model.
To implement Database/Model first approach we need to create database first,

Query to create Database in SQL Server:

CREATE DATABASE MYCART

Query To create PRODUCTS table in MYCART Database:

USE MYCART
CREATE TABLE PRODUCTS
(
 Product_ID int IDENTITY(100,1) NOT NULL primary key,
 Product_Name varchar(20),
 Product_Desc varchar(50),
 Product_Price money,
 Quantity int
)

Create New ASP.NET Application:Create application "EF_CRUD" and add AddProduct.aspx page to implement CREATE operation.

Sample Structure

Create the First simple Entity Data Model (EDM):
Solution Explorer =>right click on project => Add => New Item. Select the Data Template => ADO.NET Entity Data Model and click Add.

Rename it as ProductModel.edmx

It opens Entity Data Model Wizard. Select "Generate from database" option and click "Next"

Now enter your credentials and your database details as follows.

By double clicking on ProductModel.edmx, it will open EDM designer which displays all the entities for selected tables and relation between them.Now check Entity model will be generated like

CREATE/INSERT Operation:Check AddProduct.aspx.cs ---Download
Create instance of Context MYCARTEntities context = new MYCARTEntities();

protected void btnAdd_Click(object sender, EventArgs e)
        {
            try
            {

                PRODUCT objProduct = new PRODUCT();
                objProduct.Product_Name = txtName.Text;
                objProduct.Product_Desc = txtPdesc.Text;
                objProduct.Product_Price = decimal.Parse(txtPrice.Text);
                objProduct.Quantity = int.Parse(txtQuantity.Text);

                context.AddToPRODUCTS(objProduct);
                int result=context.SaveChanges();
                if (result != 0)
                {
                    lblMsg.Text = "Product Added!!";  
                }
                else
                {
                    lblMsg.Text = "Failed!!";
                }
                

            }
            catch (Exception ex)
            {

                lblMsg.Text = "Failed!!";
                throw ex;
            }
        }

SaveChanges() method on the context to reflect the changes back to database.This will insert the record into the table.

Now, READ,UPDATE and DELETE OPERATION:1.Add ModifyProduct.aspx page to Project
2.Add GridView to page "gvModifyProducts"
3.Use Template fields and Bound Fields to bind Data to GridView.
4.Create following Method to implement READ Operation

private void BindProductDetails()
        {
            try
            {
                var myData = from c in context.PRODUCTS select new { c.Product_ID, c.Product_Name, c.Product_Desc,       c.Product_Price,c.Quantity };
                gvModifyProducts.DataSource = myData;
                gvModifyProducts.DataBind();
            }
            catch (Exception ex)
            {
                
                throw ex;
            }
        
        
        }

5.Now handle Following events

protected void gvModifyProducts_RowEditing(object sender, GridViewEditEventArgs e)
        {
            try
            {
                gvModifyProducts.EditIndex = e.NewEditIndex;
                BindProductDetails(); 
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
        protected void gvModifyProducts_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            try
            {
                BindProductDetails();
                gvModifyProducts.PageIndex = e.NewPageIndex;
                gvModifyProducts.DataBind();
           }
            catch (Exception ex)
            {
                throw ex;
            }
         }

        protected void gvModifyProducts_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {
          gvModifyProducts.EditIndex = -1;
            BindProductDetails();

        }
        protected void gvModifyProducts_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {
            try
            {
                int intID = int.Parse(gvModifyProducts.Rows[e.RowIndex].Cells[0].Text);
                TextBox txtName = (TextBox)gvModifyProducts.Rows[e.RowIndex].Cells[1].FindControl("txtName");
                TextBox txtDesc = (TextBox)gvModifyProducts.Rows[e.RowIndex].Cells[2].FindControl("txtDesc");
                TextBox txtPrice = (TextBox)gvModifyProducts.Rows[e.RowIndex].Cells[3].FindControl("txtPrice");
                TextBox txtQuant = (TextBox)gvModifyProducts.Rows[e.RowIndex].Cells[4].FindControl("txtQuantity");
//This Code is used to handle Validations like Required field
                if (txtName.Text.Trim() == "")
                {
                    txtName.Focus();

                }
               else if (txtDesc.Text.Trim() == "")
                    txtDesc.Focus();
               else if (txtPrice.Text.Trim()=="")txtPrice.Focus();
                else if (txtQuant.Text.Trim()=="")
               txtQuant.Focus();
                else
                {
              var data =
                    (from c in context.PRODUCTS
                     where c.Product_ID == intID
                     select c).First();

                    data.Product_Name = txtName.Text;
                    data.Product_Desc = txtDesc.Text;
                    data.Product_Price = decimal.Parse(txtPrice.Text);
                    data.Quantity = int.Parse(txtQuant.Text);
                    context.SaveChanges();

                    lblMsg.Visible = true;
                    lblMsg.Text = "Product Updated Successfully!!!";
                    BindProductDetails();
                }

            }
            catch (Exception ex)
            {
                throw ex;

        {
            try
            {
                int intID = int.Parse(gvModifyProducts.Rows[e.RowIndex].Cells[0].Text);
                PRODUCT p = new PRODUCT();
                p = (from c in context.PRODUCTS
                     where c.Product_ID == intID
