    I am having an issue with RadEditor and the attribute DialogCssFile. I have previously posted this on stackoverflow, but have not yet got a reply. The basic question is

    I have a Telerik RadEditor (2017.3.913.45) control with custom/unembedded skin (created using the themebuilder on telerik), and when I enter a value for the DialogsCssFile attribute, the markup of the page changes, meaning that my custom skin is not applied to the editor anymore.

    Why is this a problem? Well the css inside the dialog for Find/replace for example didn't display correct, and having done some research, I needed to do some @imports into a customDialog.css file and drop that into the DialogsCssFile attribute.
    As soon as I do this, the generated markup in the page for RadEditor changes from

    Radeditor RadEditor_MyCustomSkin reWrapper


    Radeditor MyCustomSkin reWrapper

    meaning that my radeditor Skin is not applied to the editor, If I remove the DialogCssFile then the editor skin loads correctly, but the dialogs look wrong. In the Page source, the Window is a div within the page, and not an iFrame

    Am I doing something wrong here?


    For more detail, see my question on Stack Overflow:

    Hi Colin,

    Thank you for reporting this issue!

    To fix the DialogsCssFile problem please explicitly set the RenderMode property of RadEditor to "Lightweight", i.e.


            <telerik:RadEditor RenderMode="Lightweight"
                runat="server" ID="pageRadEdit" ToolbarMode="Default" EditModes="Design,Html"
                ToolsFile="~/App_Data/Editor.xml" Width="980px" Height="800px"
                EnableResize="false" OnClientLoad="resizeMe" NewLineMode="P"
                <SpellCheckSettings DictionaryLanguage="en-GB" AllowAddCustom="false" />
                    <telerik:SpellCheckerLanguage Code="en-GB" Title="English (UK)" />


    Best Regards,
