Se uma Web Part que implementa a interface IParametersOutConsumer do consumidor recebe o evento NoParametersOut , ele deve reutilizar seus parâmetros existentes.

Examples

O exemplo de código a seguir mostra uma implementação de um método NoParametersOut . Este exemplo de código é parte de um exemplo maior fornecido para a interface IParametersOutConsumer .

' Step #8: Implement the NoParametersOut event handler.
' The connected provider part may call this method during its PartCommunicationMain phase
' to indicate there is no change in the parameter values. This allows the consumer part to 
' display its cached data instead of potentially hitting a database again or recalculating values. 
' <param name="sender">Provider Web Part</param>
' <param name="eventArgs">The Event Argumentsr</param>
Public Sub NoParametersOut(sender As Object, eventArgs As EventArgs) Implements IParametersOutConsumer.NoParametersOut
    _noParametersOutFlag = True
         
    ' Set font attributes based on cached values.
    _fontFamily = CStr(ViewState("FontFamily"))
    _fontColor = CStr(ViewState("FontColor"))
    _fontWeight = CStr(ViewState("FontWeight"))
    _fontSize = CStr(ViewState("FontSize"))
End Sub

public void NoParametersOut(object sender, EventArgs eventArgs)
{
    _noParametersOutFlag = true;

    // Set font attributes based on cached values.
    _fontFamily = (string)ViewState["FontFamily"];
    _fontColor = (string)ViewState["FontColor"];
    _fontWeight = (string)ViewState["FontWeight"];
    _fontSize = (string)ViewState["FontSize"];
