OnClientModeChange

This event is fired before the mode is changed.

function OnClientModeChange(editor, args)
editor	object	Returns a reference to RadEditor client object
args	object	Returns the needed information about the event

The following example demonstrates how to check the current mode of Telerik RadEditor:

<script type="text/javascript">
    function OnClientModeChange(editor, args)
    {
        var mode = editor.get_mode();
        switch (mode)
        {
            case 1:
                alert("We are in Design mode");
                //do something
                break;
            case 2:
                alert("We are in Html mode");
                //do something
                break;
            case 4:
                alert("We are in Preview mode");
                //do something
                break;
        }
    }
</script>
