Preview Data Dialog Box
The Preview Data dialog box allows you to view the data returned by the TableAdapter queries in your project. You can preview data from parameterized queries by inputting parameter values for each parameter in the Parameters area.
Note When working with local data files (.mdb or .mdf files), two copies of the database are in your project. One copy is in the bin folder, and one copy is in your project folder. Any changes you make while running your application are written to the copy in the bin folder. The data displayed in the Data Preview dialog box is from the copy in the project folder. For more information, see How to: Manage Local Data Files in Your Project.
