OnClientImageChanging

The OnClientImageChanging event is raised when the user initiates an action on the image. The event can be canceled.

The event handler receives the following parameters:

1. The RadImageEditor client instance that fired the event.

2. Event arguments object. You can cancel the event by calling its set_cancel(true) method

ASP.NET

<telerik:RadImageEditor RenderMode="Lightweight" runat="server" ID="RadImageEditor1" OnClientImageChanging="OnClientImageChanging"></telerik:RadImageEditor>
<script type="text/javascript">
    function OnClientImageChanging(sender, eventArgs)
    {
        alert("OnClientImageChanging event fired by RadImageEditor with ID: " + sender.get_id());
        eventArgs.set_cancel(true); //cancels the event
    }
</script>
