    I've customized the editor toolbars by removing some buttons while adding my own custom buttons.  I've implemented a clientside OnClientCommandExecuting handler to intercept and cancel keyboard shortcuts to the removed editor buttons.  I also want to handle click events from the editor toolbar custom buttons. 

    Telerik documentation says to add onclick handlers to the editor's RadEditorCommandList.  But, I've noticed that custom button click events are first processed by the OnClientCommandExecuting handler before they get to the RadEditorCommandList handlers.  

    What is the difference between using these two handlers?  The custom buttons will instigate serverside save and saveas functionality via an ajax post.  I'ld prefer to combine everything into the OnClientCommandExecuting handler, and to launch save/saveas ajax posts from there.  After each launch I will cancel the click event.

    <script type="text/javascript">
        function OnClientCommandExecuting(editor, args) {
           if ("Save" == args.get_commandName()) {
                alert("OnClientCommandExecuting Save"); 
            } else if ("SaveAs" == args.get_commandName()) {
                alert("OnClientCommandExecuting SaveAs");
        } //EOF OnClientCommandExecuting
    <telerik:RadEditor ID="telerikeditor" Runat="server" 
            <telerik:EditorToolGroup Tag="grpInputOutput">
                <telerik:EditorTool ImageUrl="Images/radeditorSave.gif" 
                    Name="Save" ShowText="False" 
                    Text="Save" />
                <telerik:EditorTool ImageUrl="Images/radeditorSaveAs.gif" 
                    Name="SaveAs" ShowText="False" 
                    Text="Save As" />
                <telerik:EditorSeparator />     
    <script type="text/javascript"
         //locate this script after the radeditor HTML declaration
        RadEditorCommandList["Save"] = function(commandName, editor, oTool) {
            alert("RadEditorCommandList Save");

    Hi Andy ,

    Yes, the OnClientCommandExecuting event is executed before the RadEditorCommandList so that you can cancel the command execution. This is more suitable for canceling the built-in commands, but of course works for custom ones. You can implement your solution by combining everything into the OnClientCommandExecuting handler, and to launch save/saveas ajax posts from there.

    Best wishes,
