WebScheduler has OnDelete (server side event); and both OnBeforeDelete and OnAfterDelete (client side event) that will be invoked when user deletes event. You may add your own logic in those events if needed.

Please let me know your response.

hi,yudi!

I want to kown how to use OnBeforeDelete event and i want to kown how to cancel delete methord in OnBeforeDelete .

In order to cancel delete method in OnBeforeDelete client side event, you can add “return false;” line on the specific condition that you wish the deletion to be canceled.

The code snippet below shows that if the resource id of the selected event equals to “8”, then all delete operation over the events will be canceled on OnBeforeDelete client side event.

<script language="javascript" type="text/javascript">
    <!--
    function ws1_OnBeforeDelete(controlId, evt) {
        var ws1 = ISGetObject(controlId);

        if (evt.ResourceID == "8") {
            return false;
        }

        return true;
    }
    -->
</script>

Hope this helps. Please let us know if you have different scenario.
