- 10. The DataGrid View Control The DataGridView control is bound to a table in a dataset . The data fields display automatically in the cells of the grid.
- 13. Steps to Display Data in Bound Controls on a Form
- 18. Grid with Pre-Defined AutoFormat Predefined formats can be applied from the AutoFormat item on the smart tag.
- 20. .XSD File The .xsd file holds the schema of the database, where table elements, relationships, and keys can be viewed and modified
- 22. Data-Bound Text Boxes -Example Each text box or check box is bound to one field from the table. As the user clicks the navigation buttons, all controls change to display the data for the next record
- 26. Data Source Configuration Wizard
- 28. Sorting Data Click the Fill,GetData() entry in the dataset schema to display the properties of the Fill command in the Properties window. Select Ascending for the Sort Type to sort the data by the Title field. The SQL statement changes to include an ORDER BY clause
Editor's Notes
- Brief description on how to navigate within this presentation (ppt) The first time a Key Term from the chapter is used in the ppt it will display in blue Gold colored text boxes display coding examples Slides will be numbered (# of #) when multiple slides on same topic (Slide title) Speaker notes are included where appropriate for slides (*)Denotes either a comment for page reference to textbook or slide reference in ppt
- ADO.NET allows the access to database data in many formats including: OleDb, SQLClient for SQL Server (Microsoft’s proprietary DBMS), Odbc, and Oracle. Data from sources such as Access, Oracle, Sybase or DB2 can be obtained when using OleDb
- To use database file the standard terminology of relational databases needs to be understood.
- *Specifications at http://www.w3.org/XML, World Wide Web Consortium (W3C)
- Remember that controls for a Windows application are different from controls for a Web application and have different properties and events
- To set up data access in VB several classes and objects are used
- *The next slide displays the grid with a predefined format
- *The next slide displays a form with data0bound text boxes
- *The next slide displays the Data Source Configuration Wizard
- Select only the fields that are to be included in the Data Source Configuration Wizard
- You cannot sort bound data in a combo box or list box using the Sorted property of the control *The next slide displays the dialog boxes to sort data
- You can choose the control type for all controls and then drag the table to the form to create the Details view
- When you write database programs for the Web instead of Windows, you have a few more considerations—setting up data sources and bind to controls—but the Web controls are considerably different from their Windows counterpart
- Visual Studio 2005 ensures that data will be secure unless the user takes steps to unprotect the files
- You should be able to move the database projects in this chapter to another computer, open them in the IDE, and edit and/or run the applications. This is a huge improvement over earlier versions of VB .NET.
