Examples
O exemplo de código a seguir mostra um método substituído WebPart.PartCommunicationMain que cria um objeto RowReadyEventArgs , define os valores de linha e o status da seleção e, em seguida, aciona o evento de RowReady . Este exemplo de código é parte de um exemplo maior fornecido para a interface IRowProvider .
' 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 a row is selected, send the row.
If _dataGrid.SelectedIndex > - 1 Then
' Generate an array containing the selected DataRow(s).
dr(0) = CType(_dataGrid.DataSource, DataTable).Rows(_dataGrid.SelectedIndex)
' Set the selection status.
selectionStatus = "Standard"
Else
' The user hasn't selected a row so send null.
dr(0) = Nothing
' Set selection status.
selectionStatus = "None"
End If
' Set Values
rowReadyEventArgs.Rows = dr
rowReadyEventArgs.SelectionStatus = selectionStatus
' Fire the RowReady event.
RaiseEvent RowReady(Me, rowReadyEventArgs)
End If
End If
