How to enable the "Cancel button" so you can stop a report while loading ...

Question

I have seen that some reports have a Cancel button located just below "the loading ..".
How can I enable that button in MS Reporting service 2005?

Answer 1

The following mechanism responds to any of the following events: <Esc> key, Close icon ('x'), Cancel button
JavaScript part:
function popupClosedListener(event){
              var source = event.getSource();
              var popupId = source.getClientId();
              var params = {};
              params['popupId'] = popupId;
              var type = "serverPopupClosed";
              var immediate = true;
              AdfCustomEvent.queue(source, type, params, immediate);
}JSF part:
         <af:popup ....>
              <af:clientListener method="popupClosedListener"
                                       type="popupClosed"/>
              <af:serverListener type="serverPopupClosed"
                                      method="#{myBean.serverPopupClosedMetod}"/>
        </af:popup>Finally, Java part:
public void serverPopupClosedMetod(ClientEvent event){
}
