示例

下面的代码示例演示重写的WebPart.PartCommunicationMain方法创建一个RowReadyEventArgs对象，设置行值和所选内容的状态，然后将触发RowReady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 #8: Override the PartCommunicationMain method.
' The PartCommunicationMain method is called by the Web Part 
' infrastructure on the client during the 
' ASP.NET PreRender event to allow the part to pass its primary data to 
' the other connected parts.
' It is important to always fire the RowReady event. Some parts
' may not behave properly if they are left waiting for this 
' information.
Public Overrides Sub PartCommunicationMain()
   ' Check if connected
   If _connected Then
      'If there is a listener, fire the RowReady event.
      If Not (RowReady Is Nothing) Then
         ' Create the RowReadyEventArgs object for the RowReady event.
         Dim rowReadyEventArgs As New RowReadyEventArgs()
               
         ' Declare data Variables.
         Dim selectionStatus As String = ""
         Dim dr(0) As DataRow

          If _dataGrid.SelectedIndex > - 1 Then
             ' Generate an array containing the selected DataRow(s).
             dr(0) = CType(_dataGrid.DataSource, DataTable).Rows(_dataGrid.SelectedIndex)
