The code also provides direct access to named classes, methods, and events for the Data Set and its Table Adapter(s) -- Customers Table Adapter for this example -- in the Northwind Data Set. Figure 1-10 shows Internet Explorer displaying the first few lines of the 352-line schema . Customers) End Sub Figure 1-12 shows the final form after reducing the form's size, expanding the Data Grid View control to fill the available space, and pressing F5 to build, debug, and run the project. However, a Data Navigator is much more useful for a details form that displays column values in text boxes or other bound controls, such as date pickers for Date Time and checkboxes for Boolean values.
Expand the Customers node to display the Customers table's columns, as shown in Figure 1-8 The new Sql Connection object you created in preceding Steps 3 through 5 appears under Server Explorer's Data Connections node as Server Name. You can rename the node in Server Explorer to a simpler name, such as localhost.Expand the Tables node and mark the Customers table.Accept Northwind Data Set as the Data Set Name, as shown in Figure 1-7.The part of the schema that defines the elements for the table fields grows from 30 to 94 lines because element definitions now contain max Length attribute values and use restriction Base attributes to specify XSD data types. The section "Create a Complete Data Entry Form in One Step," later in this chapter, includes code to save the schema for the Northwind Customers Data Set. Changes you make to the Data Grid View don't propagate to the table until you click the Save Data button. Delete the Data Grid View control, display the Data Sources window, open the dropdown list for the Data Table, and select Details, as shown in Figure 1-13.
You can't open the saved schema in the project's Schema Designer. To make editing easier, you can automate increasing the column widths to match the content by setting the Data Grid View's Auto Size Columns Mode property value to All Cells or Displayed Cells, which adds a horizontal scrollbar to the control. Figure 1-13 Drag the Data Table icon to the form to automatically add a column of labels with associated data-bound Controls -- text boxes for this example -- to the form.
Figure 1-5 compares the objects required by updatable ADODB Recordsets and ADO. Table Adapters and Data Sets also appear in the Toolbox's Project Name Components section; the Data section has Data Set, Binding Source, and Binding Navigator controls.
