(The text length of the RadEditor control below is restricted to 150 characters.)

RadEditor offers the ability to specify the max characters lenght that will be submitted to the server by setting the MaxTextLength and MaxHtmlLength properties. This is very useful in database scenarios when the max content length of RadEditor should be set to not exceed the specified characters lenght of the database field.
The MaxTextLength property restricts only the text length of the content without checking the HTML markup, while the MaxHtmlLength property restricts the content along with the HTML markup.

Note: In order to not decrease typing, editing and pasting performance both properties check the characters length only when submitting the content.
