Examples

The following code example shows an overridden PartCommunicationInit method that creates an instance of the ParametersOutProviderInitEventArgs class to define the parameters that will be passed in the ParametersOutProviderInit event. This code example is part of a larger example provided for the IParametersOutProvider interface.

[Visual Basic]
      ' 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.
      Public Overrides Sub PartCommunicationInit()
         ' Ensure that all of the Web Part's controls are created.
         EnsureChildControls()
