Exemples
L'exemple de code suivant montre une méthode substituée PartCommunicationMainqui crée une instance de la classe ParametersInReadyEventArgs à envoyer lors de l'événement ParametersInReady se produit. Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface IParametersInProvider .
' Step #7: Implement 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 either the ParametersInReady or
' the NoParametersIn event. Some parts
' may not behave properly if they are left waiting for this
' information.
' ParametersInReady should be fired to send the parameters.
' NoParametersIn should be fired to indicate that there is no
' change in the parameters.
Public Overrides Sub PartCommunicationMain()
' Ensure that all of the Web Part's controls are created.
EnsureChildControls()
'Check if connected
If _connected Then
' Create the ParametersInReadyEventArgs object for the ParametersInReady event.
Dim parametersInReadyEventArgs As New ParametersInReadyEventArgs()
If _parametersReadyButtonClicked Then 'ParametersInReady Button was clicked
' Set the parameter values to the text box values.
If Not (_fieldList Is Nothing) Then
parametersInReadyEventArgs.ParameterValues = New String(_fieldList.Length) {}
