We often use a database backend such as
SQL Server to store data. In such databases, you have to specify the length
of any textual field when a table is designed. If you tried to insert a record whose
text length is greater than allowed by your table, an error will be reported.
To prevent this type of error from occurring, developers can use MaxHTMLLength
or MaxTextLength in the RichTextEditor to limit the length of the
user's input.
