Skip keyboard presses for some predefined commands

[QualiWareUA]

Hi guys,

I'm struggling with little problem now - how to prevent Enter hitting. For example such piece of code

function onEditorClientLoad(editor, args)
{
    editor.attachEventHandler("onkeydown",
        function(e)
        {
            if (document.all)
            {
                e.cancelBubble = true;
                e.returnValue = false;
                return false;
            }
            else
            {
                e.preventDefault();
                return false;
            }
        }
    );
}

helps us to discard any symbol key hitting, but not Enter, or Ctrl-A, and so on.
But in my case I really want to cancel Enter, if it is done inside link, and thus prevent creating two separate links.
Any help would be appreciated. Thanks in advance.

Sergey.

Hi Sergey,

You can achieve the desried behavior using the following code:

<script type="text/javascript">
    function OnClientLoad(editor, args)
    {
        editor.attachEventHandler("onkeydown", function(e)
        {
            var key = e.keyCode;
            var shift = e.shiftKey;
            if (shift && key == "13")
            {
              $telerik.cancelRawEvent(e);
              return false;
            }
            if (key == "13")
            {
              $telerik.cancelRawEvent(e);
              return false;
            }
        });
    }
</script>
<telerik:RadEditor Id="RadEditor1" Runat="server"
      OnClientLoad="OnClientLoad">
</telerik:RadEditor>

Sorry, I didn't mentioned this at first time. Setting RadEditor property

NewLineBr="false"

makes suggested by George solution unworkable in FireFox.
In IE all works fine.

Hi Sergey,

The default behavior of the Enter command in Mozilla (Gecko) editors is to insert a <br> tag. In order to provide support for paragraph insertion under Firefox we made a custom implementation (NewLineBr="false") which has its limitations because of the different browser problems and behaviors. The observed behavior is a side effect of our code which handles the enter key event. However, note that there is no need of setting the NewLineBr property, because when the enter key is prevented no new lines will be inserted.
 
I hope this helps.

Kind regards,

Hi George,

We have to set NewLineBr to false, because such behaviour is being expected by our users.
I posted here simplified project. In reality it's checked if cursor is in link scope and in this case Enter should be prevented.
It'll be really excellent if we could rewrite your Enter processor in some way. I mean using your implementation as base in every case, except some special situations as mentioned above.

Best regards,
Sergey.

Hi Sergey,

I prepared a sample code that demonstrates how to achieve the desired behavior. Please review it bellow:

<script type="text/javascript">
    function OnClientLoad(editor, args)
    {
        //IE
        editor.attachEventHandler("onkeydown", function(e)
        {
            var key = e.keyCode;
            var shift = e.shiftKey;
            if (shift && key == "13")
            {
              $telerik.cancelRawEvent(e);
              return false;
            }
            if (key == "13")
            {
              $telerik.cancelRawEvent(e);
              return false;
            }
        });
        //FF
        editor.add_commandExecuting(function(sender,args)
        {
            if (args.get_commandName() == "EnterParagraphMozilla")
            {
                args.set_cancel(true);
            }
        });
    }
</script>
<telerik:RadEditor Id="RadEditor1" NewLineBr="false" Runat="server"
      OnClientLoad="OnClientLoad">
</telerik:RadEditor>

I hope this helps.

Have a great day,
