The EnsureInterfaces method of the WebPart class provides notification for a connectable Web Part part that it should ensure all its interfaces are registered using the RegisterInterface method.
Remarks
When developing a connectable Web Part you must override the EnsureInterfaces method. Overriding this method is not necessary when you are developing a Web Part that does not support connections.
Example
The following code example shows an overridden EnsureInterfaces method. This code example is part of a larger example provided for the ICellProvider interface.
