Events Overview

Here you can learn the basics of handling RadEditor's client-side events.

The rich set of client-side events exposed in RadEditor providesflexibility—you can handle them for your project requirements or to manipulate the text being inserted and/or submitted.The available events are listed below. Each event-specific article offers concrete examples and explains the arguments each event handler receives:

To attach an event you can use either of these two approaches:

  • On the server, you can use the dedicated properties - OnClient[EventName]. The examples below showcase this technique.

Example 1: Attaching a handler in the markup via the OnClientLoad property.

<script type="text/javascript">
    function OnClientLoad(editor, args) {

        editor.attachEventHandler("onkeydown", function (e) {
            alert("Content area key down " + e.keyCode);
        });
    }
</script>

<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" OnClientLoad="OnClientLoad"></telerik:RadEditor> 

Example 2: Attaching a handler in the code behind via the OnClientLoad property.

<script type="text/javascript">
    function OnClientLoad(editor, args) {

        editor.attachEventHandler("onkeydown", function (e) {
            alert("Content area key down " + e.keyCode);
        });
    }
</script>

<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1"></telerik:RadEditor> 
RadEditor1.OnClientLoad = "OnClientLoad";
RadEditor1.OnClientLoad = "OnClientLoad"
  • On the client, to attach or detach event handlers, you should use the client-side add/remove methods - add_[EventName], remove_[EventName]. You can find a full list of the methods for attaching and detaching events in the RadEditor Object article.

Example 3: Attaching a handler via the client-side add_commandExecuted method.

<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1">
</telerik:RadEditor>

<script type="text/javascript">
    function pageLoad(sender, args) {
        var editor = $find("<%= RadEditor1.ClientID %>");

        editor.add_commandExecuted(onCommandExecuted);
    }

    function onCommandExecuted(sender, args) {
        var editor = sender;
        var executedCommand = args.get_commandName();

        alert("The " + executedCommand + " command has been executed!");
    }
</script>
