ConnectionPoint.DefaultID Field

Represents a string used to identify the default connection point within a collection of connection points associated with a server control.

Namespace:  System.Web.UI.WebControls.WebParts
Assembly:  System.Web (in System.Web.dll)

public static readonly string DefaultID

When a connection point is created, it is possible to specify an ID for the connection point in the source code of a consumer or provider WebPart control, using a ConnectionConsumerAttribute or a ConnectionProviderAttribute attribute. However, when an attribute is added to a connection point in the source code, the ID parameter is optional. If the ID is not specified in the attribute, the DefaultID field provides a string that is used to identify the default connection point.

If multiple connection points are defined in a consumer or provider control, it is necessary to specify an ID for each connection point, so that the connection points can be distinguished when creating connections.
