How to: Connect to Data in an Object

You can connect your application to data in objects by running the Data Source Configuration Wizard and selecting Object as the data source type.

After completing the wizard, a data source based on the selected object is added to your project and is immediately available in the Data Sources Window. You can drag items from the Data Sources window onto a form in your Windows application to create controls that are data-bound to the selected properties of your object. For more information, see Displaying Data Overview.

Note

The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Visual Studio Settings.
