Client-side Events Overview

RadNotification provides the following client-side events:

  • OnClientShowing - fires just before RadNotification is shown. It can be canceled.

  • OnClientShown - fires after RadNotification is shown.

  • OnClientUpdating - fires just before RadNotification content is updated. It can be canceled.

  • OnClientUpdated - fires after RadNotification content is updated.

  • OnClientUpdateError - fires if an error was thrown when RadNotification content is updated. An error alert which can be canceled is displayed.

  • OnClientHiding - fires just before RadNotification hides.

  • OnClientHidden - fires after RadNotification hides.

If a Notification Menu is configured, it has its own client events as specified in the Client-Side Events article of RadContextMenu.

To use these events, simply write a JavaScript function that can be called when the event occurs. Then assign the name of the JavaScript function as the value of the the corresponding property.

<telerik:RadNotification RenderMode="Lightweight" runat="server" ID="RadNotification1" VisibleOnPageLoad="true"
    Position="BottomRight" Width="250px" Height="100px"
    OnClientShowing="OnClientShowing" Text="Sample notification text">

<script type="text/javascript">
    function OnClientShowing(sender, eventArgs)
        alert("OnClientShowing event fired by RadNotification with id: " + sender.get_id());

You can also modify the event handlers dynamically via JavaScript. For more information see the Setting Event Handlers via JavaScript article.
