Using MVC, Entity Framework, and ASP. NET Scaffolding, you can create a web application that provides an interface to an existing database. This tutorial series shows you how to automatically generate code that enables users to display, edit, create, and delete data that resides in a database table. The generated code corresponds to the columns in the database table. In the last part of the series, you will deploy the site and database to Azure. This part of the series focuses on creating a database and populating it with data. This series was written with contributions from Tom Dykstra and Rick Anderson. It was improved based on feedback from users in the comments section. Introduction. This topic shows how to start with an existing database and quickly create a web application that enables users to interact with the data. It uses the Entity Framework 6 and MVC 5 to build the web application. The ASP. NET Scaffolding feature enables you to automatically generate code for displaying, updating, creating and deleting data. Using the publishing tools within Visual Studio, you can easily deploy the site and database to Azure. Aspdotnetsuresh offers C. VB. NET Articles,Gridview articles,code examples of asp.

This approach is called Database First development. If you do not already have an existing database, you can instead use an approach called Code First development which involves defining data classes and generating the database from the class properties. For an introductory example of Code First development, see Getting Started with ASP. NET MVC 5. For a more advanced example, see Creating an Entity Framework Data Model for an ASP.

Prerequisites. Visual Studio 2. Visual Studio Express 2. Web. Set up the database. To mimic the environment of having an existing database, you will first create a database with some pre filled data, and then create your web application that connects to the database. This tutorial was developed using Local. DB with either Visual Studio 2. Visual Studio Express 2. Web. You can use an existing database server instead of Local. DB, but depending on your version of Visual Studio and your type of database, all of the data tools in Visual Studio might not be supported. If the tools are not available for your database, you may need to perform some of the database specific steps within the management suite for your database. If you have a problem with the database tools in your version of Visual Studio, make sure you have installed the latest version of the database tools. For information about updating or installing the database tools, see Microsoft SQL Server Data Tools. Launch Visual Studio and create a SQL Server Database Project. Name the project Contoso. University. Data. You now have an empty database project. You will deploy this database to Azure later in this tutorial, so youll need to set Azure SQL Database as the target platform for the project. Setting the target platform does not actually deploy the database it only means that the database project will verify that the database design is compatible with the target platform. To set the target platform, open the Properties for the project and select Microsoft Azure SQL Database for the target platform. You can create the tables needed for this tutorial by adding SQL scripts that define the tables. Right click your project and add a new item. SecurityStudy. Add a new table named Student. In the table file, replace the T SQL command with the following code to create the table. CREATE TABLE dbo. Student. Student. ID INT IDENTITY 1, 1 NOT NULL. Last. Name NVARCHAR 5. NULL. First. Name NVARCHAR 5. NULL. Enrollment. Date DATETIME NULL. PRIMARY KEY CLUSTERED Student. ID ASC. Notice that the design window automatically synchronizes with the code. You can work with either the code or designer. Add another table. This time name it Course and use the following T SQL command. CREATE TABLE dbo. Course. Course. ID INT IDENTITY 1, 1 NOT NULL. Title NVARCHAR 5. NULL. Credits INT NULL. PRIMARY KEY CLUSTERED Course. ID ASC. And, repeat one more time to create a table named Enrollment. CREATE TABLE dbo. Enrollment. Enrollment. ID INT IDENTITY 1, 1 NOT NULL. Grade DECIMAL3, 2 NULL. Course. ID INT NOT NULL. Student. ID INT NOT NULL. PRIMARY KEY CLUSTERED Enrollment. ID ASC. CONSTRAINT FKdbo. Enrollmentdbo. CourseCourse. ID FOREIGN KEY Course. ID. REFERENCES dbo. Course Course. ID ON DELETE CASCADE. CONSTRAINT FKdbo. Enrollmentdbo. StudentStudent. ID FOREIGN KEY Student. ID. REFERENCES dbo. Student Student. ID ON DELETE CASCADE. You can populate your database with data through a script that is run after the database is deployed. Add a Post Deployment Script to the project. You can use the default name. Add the following T SQL code to the post deployment script. This script simply adds data to the database when no matching record is found. It does not overwrite or delete any data you may have entered into the database. MERGE INTO Course AS Target. Economics, 3. 2, Literature, 3. Chemistry, 4. AS Source Course. ID, Title, Credits. ON Target. Course. ID Source. Course. ID. WHEN NOT MATCHED BY TARGET THEN. INSERT Title, Credits. VALUES Title, Credits. MERGE INTO Student AS Target. Tibbetts, Donnie, 2. Guzman, Liza, 2. Catlett, Phil, 2. AS Source Student. ID, Last. Name, First. Name, Enrollment. Date. ON Target. Student. ID Source. Student. ID. WHEN NOT MATCHED BY TARGET THEN. INSERT Last. Name, First. Name, Enrollment. Date. VALUES Last. Name, First. Name, Enrollment. Date. MERGE INTO Enrollment AS Target. AS Source Enrollment. ID, Grade, Course. ID, Student. ID. ON Target. Enrollment. ID Source. Enrollment. ID. WHEN NOT MATCHED BY TARGET THEN. INSERT Grade, Course. ID, Student. ID. VALUES Grade, Course. ID, Student. ID. It is important to note that the post deployment script is run every time you deploy your database project. Therefore, you need to carefully consider your requirements when writing this script. In some cases, you may wish to start over from a known set of data every time the project is deployed. In other cases, you may not want to alter the existing data in any way. Based on your requirements, you can decide whether you need a post deployment script or what you need to include in the script. For more information about populating your database with a post deployment script, see Including Data in a SQL Server Database Project. You now have 4 SQL script files but no actual tables. You are ready to deploy your database project to localdb. In Visual Studio, click the Start button or F5 to build and deploy your database project. Check the Output tab to verify that the build and deployment succeeded. To see that the new database has been created, open SQL Server Object Explorer and look for the name of the project in the correct local database server in this case localdbProjects. V1. 2. To see that the tables are populated with data, right click a table, and select View Data. An editable view of the table data is displayed. Your database is now set up and populated with data. In the next tutorial, you will create a web application for the database. Dynamically AddRemove rows in HTML table using Java. Scriptad nameADINBETWEENPOST A good web design involves the better user interaction and ability to fetch the data in a better way. For fetching user data, you may have to create a form wherein user can add multiple entries and submit them simultaneously. Thus for this you will need a way to add or remove fields dynamically into the HTML page. In my previous article, I had discussed about the way one can add dynamic form components into the web page. In this article we will create a user interface where user can adddelete multiple rows in a form using Java. Script. First check the user interface. In this example, we have created a table which will display our html components. On pressing Add Row, a dynamic row will be created and added in the table. And on selecting the checkbox and pressing Delete Row, the row will be removed. Following is the source. Codelt HTML. TITLE AddRemove dynamic rows in HTML table lt TITLE. SCRIPT languagejavascript.

This method will insert a row at position specified by the index arguement. Also for removing row, we have used delete. Row method. Note that for inserting dynamic row, we have to created cells by using row. Cell method. Check the online demo. Online Demo. Click here. AddRemove rows from table having Drop Down List. What if my table has a selectbox or drop down list and I want to implement addremove row functionality A lot of people asked me this question you can check comment section, so I thought to update this article and add one more case. Adding Removing rows in a table having drop down list. Following is the code lt HTML. TITLE AddRemove dynamic rows in HTML table lt TITLE. SCRIPT languagejavascript. Rowtable. ID. Element. By.

I have edited this piece of code from our previous example. The add. Row method iterates through all the columns and copy the content of 1st column to new column. This way a new row is created which is exact copy of 1st row. Also the switch case in the code make sure that the value are not copied as it is. For example, if you have entered text abc in textbox of 1st row and you press Add Row button, the new row will be added and the textbox of this new row will have value abc. So to make sure the values are not copied, we have added the switch code. You may want to comment the switch code if the copying of the values in newly added row if desired to you. Online Demo.

Hence we may want to submit the above form and fetch its values in PHP to store the data in database. If you notice we have multiple input textboxes with the same name. So in order to get these values in PHP request parameter, we need to modify our HTML. We need to append at the end of name of each input boxes including select box. Thus our textbox definition lt INPUT typetext nametxt. Will change into lt INPUT typetext nametxt. Also the checkbox and select box definition change to lt INPUT typecheckbox namechk. SELECT namecountry. OPTION valuein Indialt OPTION. OPTION valuede Germanylt OPTION. OPTION valuefr Francelt OPTION. OPTION valueus United Stateslt OPTION. OPTION valuech Switzerlandlt OPTION. SELECT. Once we have changed the HTML code, add a submit button at the end of the form and submit this form to Fetchrequest. Following will be the code to get the values from request in PHP and displaying them on screen lt POSTchk. POSTtxt. POSTcountry. If you read this far, you should follow me on twitter here.
