Examples
The following code example shows an overridden WebPart.PartCommunicationInit method that creates an instance of the ListProviderInitEventArgs class to send when the ListProviderInit event occurs. This code example is part of a larger example provided for the IListProvider interface.
' Step #7: Override 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. 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.
' Ensure that all of the Web Part's controls are created.
EnsureChildControls()
' Check if connected.
If _connected Then
'Create the ListProviderInitEventArgs object for the ListProviderInit event.
Dim listProviderInitArgs As New ListProviderInitEventArgs()
' Set the list field names.
listProviderInitArgs.FieldList = _listFieldNames
listProviderInitArgs.FieldDisplayList = _listFieldDisplayNames
' Fire the ListProviderInit event.
ListProviderInit(Me, listProviderInitArgs)
End If
