Hi Ali,

The requested functionality is discussed at the following forum thread: 

Getting Row Count.

Please check it out, if needed improve the implementation and if you'd like share it with the community.

Hello,

RadEditor is a rich text editor but not a textbox for plain text editor. As such it allows HTML tags and formatting inside its content area.

If you want to obtain the content as plain text you can do it via:

• the Text server property - https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/accessibility-and-internationalization/localization/text-property
• or the get_text() client side method -  https://www.telerik.com/forums/charector-limit-in-rad-editor#ommxkH-VxEyG4QLNfkrAuA.
• You may be also interested in the MaxTextLength property which restricts only the text length of the content without checking the HTML markup: https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/max-content-length-
