Remarks

Using the Web Parts control set, you can enable two server controls to form a connection and share data, with one control acting as the data provider and the other acting as the data consumer. The two controls can be WebPart controls or any other type of server control, provided that they are designed to handle connections and are residing in a WebPartZoneBase zone.

For more information on the ConnectionsZone and Web Parts controls, see ASP.NET Web Parts Pages.

Example

The following code example demonstrates how to use the ConnectionsZone control on a Web page declaratively. Within the element, a number of properties are set declaratively. Other properties on the connections zone are set programmatically in the script section of the page.

For the definitions for the user control and the custom control that is defined with @ Register directives, see the "Example" in the class overview for ConnectionsZone.
