HtmlEditor icons are not displayed in a custom Default theme if ToolbarMode is Menu

It's working, thanks

Hi,
We still continue with the issue, we updated to the lastest version (15.2.5).
We make a new project from scratch with the last version, and we still have the problem of missing icons on Toolbar in HtmlEditor.
What can we do resolve the problem?

Thanks for the clarification. I see that the problem still persists if ToolbarMode is Menu. This behavior looks incorrect and I've forwarded it to our R&D team for further research.  We'll post our results here. Please bear with us.
In the meantime, I suggest using Ribbon as a toolbar.

C#
settings.ToolbarMode = HtmlEditorToolbarMode.Ribbon;  

Thanks,
Artem

We have fixed the issue and introduced the following behavior. Menu icons are set up using the HtmlEditorImages.MenuIconSet  property. For the Default theme, it's set to MenuIconSetType.NotSet (no icons are displayed) in the .skin file. When you're creating a custom theme based on the Default theme, this property isn't changed either. We don't automatically change it in order to provide you with the capability to define a custom set of images. So, you need to manually set this property to a required value. To enable icons in this case, the following steps are required:

1. Load a required icon set using the ExtensionsFactory.GetStyleSheets method:

C#
@Html.DevExpress().GetStyleSheets(  
    new StyleSheet { ExtensionSuite = ExtensionSuite.HtmlEditor, MenuIconSet = DevExpress.Web.MenuIconSetType.Colored }  
)  

2. Set up the MenuIconSet property for the HtmlEditorSettings object:

C#
@Html.DevExpress().HtmlEditor(settings => {  
         settings.Name = "he";  
         settings.Images.MenuIconSet = MenuIconSetType.Colored;  
          ...  
}).GetHtml()  

As an alternative solution, you can set up this property at the theme level (see the image). In this case, there is no need to perform additional registrations.

If you decide to use different icon sets for different HtmlEditors, it will be necessary to register additional icon sets using the ExtensionsFactory.GetStyleSheets method, as shown at step 1 and assign a delegate method to the PreRender property:

C#
@Html.DevExpress().HtmlEditor(settings => {  
         settings.Name = "he";  
         settings.PreRender = (s,e) =>{  
              ((MVCxHtmlEditor)s).Images.MenuIconSet = MenuIconSetType.Colored  
         };  
          ...  
}).GetHtml()  

Attached is a test sample illustrating these ideas. Note that these changes will have effect only with the applied hot fix.
