Examples
The following code example shows an overridden WebPart.PartCommunicationInit method that creates a RowProviderInitEventArgs object, sets field names and display names, and then fires the RowProviderInit event. This code example is part of a larger example provided for the Microsoft.SharePoint.WebPartPages.Communication.IRowProvider interface.
' 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
