To connect the data control to this database, double-click the DatabaseName property in the Properties window and then click on the button with three dots on the right as shown in Figure MDB, as shown in Figure You can also change the caption of the data control to anything, we use Click to browse Customers. After that, we will place a label and change its caption to Customer Name.
We need to bind this label to the data control for the application to work. One more thing that we need to do is to bind the label to the correct field so that data in this field will appear on this label. In our example, we named the first table Inventory and the second table Stock. After designing the tables, we can then proceed to create a database that comprises the two tables.
Visual Data Manager can be used to create tables, add new data as well as edit data. Besides that, it can be used to modify table structure. To learn how to create database using Visual Data Manager, follow the link below:. The next step is to insert some relevant controls into the form for displaying and manipulating the data of the database. DataGrid controls and FlexGrid controls are used to display and store the data from the database tables. As ADO is ActiveX-based, it can work in different platforms different computer systems and different programming languages.
Besides, it can access many different kinds of data such as data displayed in the Internet browsers, email text and even graphics other than the usual relational and non relational database information. To be able to use ADO data control, you need to insert it into the toolbox. The first is to deal with data in the Inventory table and the second is to deal with data in the Stock table. They are use to display the data to the user. Besides, we insert one FlexiGrid control to store the data and also to print out the data by connecting it to MS Excel spreadsheet.
After inserting the necessary controls, it is time to write code to coordinate the controls and to manipulate the data. The first most important code for our program is to connect the ADO controls to the database when the form is loaded. The code is as shown below:. Refresh Set DataInventory. Refresh Set DataStock. In this tutorial, we use the Microsoft Entity Framework.
However, it is important to understand that you can use a variety of different technologies to interact with a database from an ASP. Follow these steps to complete the wizard:. The Designer should display the Movies entity see Figure 2.
We need to make one change before we continue. The Entity Data Wizard generates a model class named Movies that represents the Movies database table. Because we'll use the Movies class to represent a particular movie, we need to modify the name of the class to be Movie instead of Movies singular rather than plural.
Double-click the name of the class on the designer surface and change the name of the class from Movies to Movie. After making this change, click the Save button the icon of the floppy disk to generate the Movie class. Now that we have a way to represent our database records, we can create a controller that returns the collection of movies. Click the Add button to add the new controller. Figure 04 : The Add Controller dialog Click to view full-size image.
We need to modify the Index action exposed by the Movie controller so that it returns the set of database records. Modify the controller so that it looks like the controller in Listing 1.
The expression entities. ToList returns the set of all movies from the Movies database table. The easiest way to display a set of database records in an HTML table is to take advantage of the scaffolding provided by Visual Studio. Build your application by selecting the menu option Build, Build Solution.
You must build your application before opening the Add View dialog or your data classes won't appear in the dialog. Right-click the Index action and select the menu option Add View see Figure 5. Figure 05 : Adding a view Click to view full-size image. In the Add View dialog, check the checkbox labeled Create a strongly-typed view.
