I am wondering if anyone has came across a solution for limiting the length of characters in either CKEditor or  RadEditor (either one will do).

I saw generic (non-DNN) implementation of this fearture, but many lack copy and and paste while it will limit keystokes only.

For me it is a vital feature. 

Thanks Sebastian for your reply, but I found a better way, and would like to share it.

1. Install  dnnWerk.RadEditorProvider, one can customize the toolbox and other features, per user role.

 2. Open the ConfigDocumented.xml  in the Telerik folder \Providers\HtmlEditorProviders\Telerik  with full reference  to all the additional options.

 3. Copy

<property name="MaxTextLength">xxxxx</property>

and paste it in the config file of the user group and portal number you have customized  it is here \DesktopModules\dnnWerk.RadEditorProvider\ConfigFil

In my case it is ConfigFile.Registered.PortalId.0.xml

     xxxx state the max length of the text (integer)

I tried it and it works, I get popup dialog box with the error  “1000 . . “  1000 is  the the value of the max length of the text one has selected.

I can not find a way to place my own error message saying "The max length permitted is 1000 characters, please go back and reduce the text length"”

From the Repository module, I know this is implemented by the resx file, but I need to place the reference in the resx file and insert my custom error message.
