Parameter	Description
value	The value to be assigned to the property. Value can be a quoted DataWindow expression. Values are: Yes – DataWindow HTML generation uses the HTMLGen properties. No – DataWindow HTML generation is a read-only. table as described for the Data.HTMLTable property.

Usage

When HTMLDW is set to Yes, the generated HTML supports data
entry and takes advantage of browser features that enable user interaction
when used with a page server (as described for the Data.HTML property).
The generated HTML can be used to produce a page that displays a
subset of retrieved rows and can include JavaScript code requesting
additional pages with other subsets of the retrieved rows.

The resulting HTML can be used as a Web DataWindow control,
which is a cooperation between a server component, a page server,
and a client Web browser. The server component produces the HTML
and the page server incorporates it into a Web page.

The user interacts with the DataWindow in the client browser,
and actions produced by buttons in the DataWindow object are sent
back to the page server. The page server calls methods of the server
component to request processing for the data in the DataWindow object,
including applying actions, updating data, and scrolling to other
subsets.

For more information, see the DataWindow Programmers
Guide. To affect the level of DataWindow features in
the resulting HTML, or to produce master/detail links between
two Web DataWindow controls, see HTMLGen.property.

DataWindow features that will not be rendered into HTML include:

• Graph, OLE, and RichText presentation styles and
  controls.

• Client-side expressions that include aggregate functions.
  Aggregate functions cannot be evaluated in the browser. Instead,
  they will be evaluated on the server and the resulting value included
  in the HTML.

• Resizable and movable controls.

• Sliding of controls to fill empty space.

• Autosizing of height or width.

• EditMasks for column data entry.
