' Step #9: Override the PartCommunicationInit() method
' PartCommunicationInit() is called by the Web Part infrastructure during the ASP.NET PreRender
' event to allow the part to pass initialization information to the other connected parts.
' It is important to always pass initialization information as some parts
' may not behave properly if this initialization information is not received.
Public Overrides Sub PartCommunicationInit()
' Check if connected
If _connected Then
' Create the InitEventArgs structure for the CellProviderInit event.
Dim cellProviderInitArgs As New CellProviderInitEventArgs()
' Set the FieldName and FieldDisplay values.
cellProviderInitArgs.FieldName = _cellName
cellProviderInitArgs.FieldDisplayName = _cellDisplayName
' Fire the CellProviderInit event.
