Undo/Redo functionality does not work correctly in IE9

[Toldo]

Hello,
We faced a problem that undo/redo functionality does not work correctly in IE9.
The issue can be reproduced on RadEditor demo.

1. Place a cursor into the text begining.
2. Press Enter several times.
Undo/Redo buttons do not work for such a change.

Could you please respond if it can be fixed?

Hi Toldo,

We are aware of this issue - the Enter command in RadEditor is not logged currently in the Undo/Redo list to not decrease the editing performance when editing a large document as well as to eat memory.

Nevertheless, you can add it to the list using the following code (note that the NewLineMode property should be set to "P", which inserts the paragraph mode):

<telerik:RadEditor ID="RadEditor1" runat="server" NewLineMode="P" OnClientLoad="OnClientLoad"></telerik:RadEditor>
<script type="text/javascript">
    function OnClientLoad(editor, args)
    {
        editor.attachEventHandler("onkeydown", function (e) {
            if (e.keyCode == 13) {
                var oCmd = new Telerik.Web.UI.Editor.GenericCommand("Enter", editor.get_contentWindow(), editor);
                editor.executeCommand(oCmd);
            }
        });
    }
</script>
