I’m upgrading an ASP.NET solution from AjaxControlToolkit V4.x to V17.x. The original HTMLEditor was deprecated and HtmlEditorExtender shall now be used instead. My HTML editor contains a few custom toolbar buttons, which need to be migrated. Unfortunately, I couldn’t find any examples on how to add custom toolbar buttons to the HtmlEditorExtender.

An example on how to add a toolbar button „H1“, which applies the h1 style to the selected text would be very helpful.

Also, HTMLEditor offered these properties to set a specific style sheet (which can be selected by the user dynamically at runtime):

htmlEditorEx.DesignPanelCssPath
htmlEditorEx.DocumentCssPath

Is there an equivalent in HtmlEditorExtender?

While you can extend a HtmlEditorExtenderButton class, HtmlEditorExtender's client code has no logic that runs custom client behavior of a button.

I see the only valid option is to extend HtmlEditorExtender itself and add your custom logic to a client code that executes button logic.

  • Thanks for your reply. After spending hours with the HtmlEditorExtender, I decided to go with a commercial editor. Your reply backs that decision. – Hirnilein0815 Jun 01 '17 at 10:43
