Bind controls to data in Visual Studio

 

You can display data to users of your application by binding data to controls. You can create these data-bound controls by dragging items from the Data Sources window onto a design surface or controls on a surface in Visual Studio.

This topic describes the data sources you can use to create data-bound controls. It also describes some of the general tasks involved in data binding. For more specific details about how to create data-bound controls, see Bind Windows Forms controls to data in Visual Studio and Bind WPF controls to data in Visual Studio.

In the context of data binding, a data source represents the data in memory that can be bound to your user interface. In practical terms, a data source can be an Entity Framework class, a dataset, a service endpoint that is encapsulated in a .NET proxy object, a LINQ to SQL class, or any .NET object or collection. Some data sources enable you to create data-bound controls by dragging items from the Data Sources window, while other data sources do not. The following table shows which data sources are supported.

  1. Generate the model using the Entity Data Model wizard, then drag those objects to the designer.

  2. LINQ to SQL classes do not appear in the Data Sources window. However, you can add a new object data source that is based on LINQ to SQL classes, and then drag those objects to the designer to create data-bound controls. For more information, see Walkthrough: Creating LINQ to SQL Classes (O-R Designer).

Data sources are available to your project as items in the Data Sources window. This window is visible, or is accessible from the View menu, when a form design surface is the active window in your project. You can drag items from this window to create controls that are bound to the underlying data, and you can also configure the data sources by right-clicking.

Data Sources window

For each data type that appears in the Data Sources window, a default control is created when you drag the item to the designer. Before you drag an item from the Data Sources window, you can change the control that will be created. For more information, see Set the control to be created when dragging from the Data Sources window.
