Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|WebPartConnectionsEventArgs(WebPart, ProviderConnectionPoint, WebPart, ConsumerConnectionPoint)||Initializes a new instance of the class without requiring a WebPartConnection object.|
|WebPartConnectionsEventArgs(WebPart, ProviderConnectionPoint, WebPart, ConsumerConnectionPoint, WebPartConnection)||Initializes a new instance of the class using the specified WebPartConnection object.|
|Connection||Gets the WebPartConnection object of the current connection.|
|Consumer||Gets the WebPart control that is acting as the consumer in the connection.|
|ConsumerConnectionPoint||Gets the ConsumerConnectionPoint object of the current connection.|
|Provider||Gets the WebPart control that is acting as the provider in the connection.|
|ProviderConnectionPoint||Gets the ProviderConnectionPoint object of the current connection.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Using the capabilities of the Web Parts control set, it is possible to create a connection between two WebPart or other server controls, with one control acting as the provider, and the other acting as the consumer of data. To form a connection, the two controls must reside in a zone that inherits from the WebPartZoneBase class (such as the WebPartZone control), and they must be designed correctly to share data through a common interface. For details about Web Parts connections, see WebPartConnection and Web Parts Connections Overview.
The class passes event data to methods that use the WebPartConnectionsEventHandler delegate to handle events. There are two such connection-related methods that raise events and use the class to provide event data. Both are members of the WebPartManager control. The OnWebPartsConnected method raises the WebPartsConnected event after two server controls have successfully connected, and the OnWebPartsDisconnected method raises the WebPartsDisconnected event after two server controls have been disconnected.
Developers can create custom event handler methods for the WebPartsConnected and WebPartsDisconnected events, and in those methods, they can use the class to access details of a connection. For example, a developer can declare the OnWebPartsConnected attribute on the <asp:webpartmanager> element, and assign to it a custom method name that will handle the event. In the custom handler method, developers can access the details of a connection by using the object that is passed to the method as a parameter.
The class has two overloads of the constructor. The WebPartConnectionsEventArgs.WebPartConnectionsEventArgs(WebPart, ProviderConnectionPoint, WebPart, ConsumerConnectionPoint) constructor is the default; it initializes the property values for the class. The WebPartConnectionsEventArgs.WebPartConnectionsEventArgs(WebPart, ProviderConnectionPoint, WebPart, ConsumerConnectionPoint, WebPartConnection) constructor calls the default constructor, and then it also initializes the Connection property.
The class has several properties, all of which refer to the essential aspects of a Web Parts connection. The Connection property refers to the associated WebPartConnection object that represents the entire connection. The Provider property references a WebPart or other server control acting as the provider in the connection, and the Consumer property references a WebPart or server control acting as the consumer. The ProviderConnectionPoint property references the connection's ProviderConnectionPoint object, while the ConsumerConnectionPoint property references the ConsumerConnectionPoint object.
