示例
下面的代码示例演示将触发FilterConsumerInit事件重写的PartCommunicationInit方法。此代码示例是示例的一个更大提供的IFilterConsumer接口的一部分。
' 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()
' If the connection wasn't actually formed then we don't want to
' send the Init event.
If _connected Then
' Ensure that all of the Web Part's controls are created.
' The _filterFieldNames and _filterFieldDisplayNames are set
' during EnsureChildControls().
EnsureChildControls()
' Create the FilterConsumerInitEventArgs object for the
' FilterConsumerInit event.
Dim filterConsumerInitArgs As New FilterConsumerInitEventArgs()
' Set the field names.
filterConsumerInitArgs.FieldList = _filterFieldNames
filterConsumerInitArgs.FieldDisplayList = _filterFieldDisplayNames
' Fire the FilterConsumerInit event.
RaiseEvent FilterConsumerInit(Me, filterConsumerInitArgs)
End If
