![]() ![]() For more information, see BindingSource Component Architecture. If you start adding items to the BindingSource component without first specifying a list to be bound to, the component will act like a list-style data source and accept these added items.Īdditionally, you can write code to provide custom "AddNew" functionality by means of the AddingNew event, which is raised when the AddNew method is called prior to the item being added to the list. Also see Bind Windows Forms controls to data in Visual Studio. The following illustration demonstrates where the BindingSource component fits into the existing data-binding architecture.Īt design time, some actions, like dragging a database table from a data window onto a blank form, will create the BindingSource component, bind it to the underlying data source, and add data-aware controls all in one operation. At design time or run time, you can bind a BindingSource component to a complex data source by setting its DataSource and DataMember properties to the database and table, respectively. The BindingSource component acts as an intermediary that provides binding and currency management services. ![]() You can bind the BindingSource component to both simple data sources, like a single property of an object or a basic collection like ArrayList, and complex data sources, like a database table.

The BindingSource component acts as the data source for some or all of the controls on the form. BindingSource Component as an Intermediary Additionally, you can add data directly to it, so that the component itself functions as a data source. ![]() It provides an abstraction of your form's data connection while passing through commands to the underlying list of data. The BindingSource component acts as both a conduit and a data source for other controls to bind to. The BindingSource component is designed to simplify the process of binding controls to an underlying data source. ![]()
