First, you’ll create a method, FillDBGrid, which fills a DataSet object. Then you’ll read data from a DataSet object and populate the DataGrid control. The Fill method of SqlDataAdapter fills data from a data adapter to the DataSet. You call Fill method in FillDBGrid method. Once you have a DataSet containing data, you can do anything with it including creating views for that data. DefaultViewManager, which binds the DataSet object to the DataGrid control (see Listing 4-3). Listing 4-3. DefaultViewManager; } Now you simply call FillDBGrid from the Form1 constructor or the Form_Load event or from a button-click handler.

You can use the Data Form Wizard to develop your database application with viewing, updating, and deleting capabilities. NET (unless you’re an extremely fast typist). In this section, you’ll use a Data Form Wizard to write a fully functioning database application including features such as inserting, updating, and deleting data without writing a single line of code.

Listing 4-4. Calling the FillDBGrid method from the Form1 constructor public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); FillDBGrid(); // // TODO: Add any constructor code after InitializeComponent call // } 189 933ch4 3/20/02 11:03 AM Page 190 Chapter 4 Now build and run the project.
