Notification / Show




If the ShowInterval property is set to an int value, the notification will automatically show after that interval of milliseconds. To stop it - set it to 0 (default value)
RadNotification exposes a server method Show() - when called, the notification will show, no matter you update it or not if called with AJAX
 VisibleOnPageLoad='False'
 RadNotification exposes a server property VisibleOnPageLoad - when set to true, the notification will show. If set with with AJAX request, the notification should also be updated
RadNotification exposes can be also shown on the client by using the client-side method show()

  • Show

    RadNotification provides the following 4 basic manners to show it:

    • ShowInterval property - if set to a positive int value, the notification will automatically show after that interval of milliseconds. To stop it - set it to 0 (default value)

    • Server Show() - when called, the notiofication will show, no matter you update it or not if called with AJAX

    • VisibleOnPageLoad property - when set to true, the notification will show. If set with with AJAX request, the notification should also be updated

    • Client show() - used to show notification client-side
