IParametersOutProvider.ParametersOutProviderInit event
NOTE: This API is now obsolete.
Allows the provider Web Part to pass initialization information about the parameters it is providing to the other connected parts.
Namespace: Microsoft.SharePoint.WebPartPages.Communication
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Examples
The following code example shows an overridden WebPart.PartCommunicationInit method that fires the ParametersOutProviderInitevent. This code example is part of a larger example provided for the IParametersOutProvider interface.
' Step #7: Override the PartCommunicationInit method.
' The PartCommunicationInit method is called by the Web Part
' infrastructure during the ASP.NET PreRender
' phase to allow the part to pass initialization information to
' the other connected parts.
' It is important to always pass initialization information. Some
' parts may not behave properly if this initialization
' information is not received.

' Ensure that all of the Web Part's controls are created.
