Partial support for SaveDocument function

The SaveDocument function for RichTextEdit controls is supported for the TXT format, but HTML tags are saved in the text file. SaveDocument can also save text and images to HTML and DOC file formats, however, it cannot correctly save Unicode characters in these file formats. SaveDocument does not support RTF or PDF formats in Web Forms applications.

Controls in DataWindow objects

Table 8-5 lists the properties that are not supported in Web Forms applications for controls that you can place in a DataWindow object.
