If your database requires a password, select the option to include sensitive data, and then click Next. Select New Connection to launch the Add/Modify Connection dialog box. If a data connection to the Northwind sample database is available in the drop-down list, select it. On the Choose your Data Connection page do one of the following: Select Database on the Choose a Data Source Type page, and then click Next. In the Data Sources window, select Add New Data Source to start the Data Source Configuration wizard. To open the Data Sources window, on the Data menu, click Show Data Sources. This step creates a data source from a database using the Data Source Configuration wizard:

Paste the T-SQL script into the query editor, and then choose the Execute button.Īfter a short time, the query finishes running and the Northwind database is created.Ĭreate a new Windows Forms App (.NET Framework) project for either C# or Visual Basic. This T-SQL script creates the Northwind database from scratch and populates it with data. Right-click on your LocalDB instance and select New Query.Ĭopy the Northwind Transact-SQL script to your clipboard. (SQL Server Object Explorer is installed as part of the Data storage and processing workload in the Visual Studio Installer.) Expand the SQL Server node.

This walkthrough uses SQL Server Express LocalDB and the Northwind sample database. You must have the Data storage and processing workload installed. NET Framework Windows Forms projects, not to. The procedures in this article apply only to. Setting the drop type of the items in the Data Sources window.Ĭreating controls that display data by dragging items from the Data Sources window onto a form.Īdding controls to display the data on the form.Ĭompleting the Search Criteria Builder dialog box.Įntering parameters into the form and executing the parameterized query. Tasks illustrated in this walkthrough include:Ĭreating and configuring the data source in your application with the Data Source Configuration wizard.
Open the dialog box by selecting the Add Query command on the Data menu (or on any TableAdapter smart tag). You can add parameterized queries to any TableAdapter (and controls to accept parameter values and execute the query), using the Search Criteria Builder dialog box. In contrast, if you request an entire database table, transfer it over the network, and then use application logic to find the records you want, your application can become slow and inefficient. Using parameterized queries helps make your application efficient by letting the database do the work it is best at - quickly filtering records.

This walkthrough shows how to create a query that returns customers in a specific city, and modify the user interface so that users can enter a city's name and press a button to execute the query. The query returns only the data that satisfies the criteria entered by the user.
