When the NewLineMode of a RadEditor is set to Div and a line of text is entered in an empty content area of the control under Chrome, the text will be wrapped in a paragraph element. Possible workaround is to set an initial content with a DIV and BR elements inside: <telerik:RadEditor runat="server" ID="RadEditor1" NewLineMode="Div"> <Content> <div></div> </Content> </telerik:RadEditor> Another possible solution is incorporating the following JS code right after the RadEditor declaration: <telerik:RadEditor runat="server" ID="RadEditor1" NewLineMode="Div"> </telerik:RadEditor> <script type="text/javascript"> Telerik.Web.UI.RadEditor.prototype._onKeyPressed = function (e) { } </script>
