示例
下面的代码示例演示重写的WebPart.PartCommunicationInit方法创建一个RowProviderInitEventArgs对象，设置字段名称和显示名称，然后将触发RowProviderInit事件。此代码示例是示例的一个更大提供的IRowProvider接口的一部分。
' Step #7: Override the PartCommunicationInit() method.
' The PartCommunicationInit method 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.
EnsureChildControls()
' Check if connected.
If _connected Then
' Create the RowProviderInitEventArgs object for the
' RowProviderInit event.
Dim rowProviderInitEventArgs As New RowProviderInitEventArgs()
' Set the row field names.
rowProviderInitEventArgs.FieldList = _rowFieldNames
' Set the row field display names.
rowProviderInitEventArgs.FieldDisplayList = _rowFieldDisplayNames
' Fire the RowProviderInit event.
RaiseEvent RowProviderInit(Me, rowProviderInitEventArgs)
End If
End Sub
