    Hi Padma,

    In case u r using EVS, any event related to that can not be captured bcos everything in handled by framework.

    For ur requirement better go to OVS.

    regards

      	WDValueServices.addOVSExtension("Data Selection",ovsStartUpAttributes,
      									  wdThis.wdGetCustOVSController().getOVSInputNode(),
      									  wdThis.wdGetCustOVSController().getOVSOutputNode(),listener);
