Setting Web DataWindow design-time control properties

The previous section, “Designing DataWindow objects for the Web DataWindow,” began on page § and covered many topics about the design of DataWindow objects that are to be used as Web DataWindows. Now we look at the integrated support in PowerBuilder for creating and editing Java Server Pages (JSPs) for the Web DataWindow.

JavaServer pages

JSP pages can be written in any well-formed language, including XML, but they are usually written in HTML. In PowerBuilder, you usually create JSPs for use with Web DataWindows using the Web/JSP DataWindow Page wizard, and you edit them in much the same way as any other HTML page, using the HTML editor. In the Web/JSP DataWindow Page wizard, you specify whether you are using the Standard HTMLGenerator105 component, a custom HTMLGenerator105 component that you developed and deployed to EAServer, or a DataWindow container.

DTC properties

When the page is created, it contains a Web DataWindow design-time control (DTC). A Web DataWindow DTC lets you add database-driven content to Web applications.

In the Sybase Web DataWindow DTC Properties dialog box, you can specify the type of generation you want. The generation type determines the method that PowerBuilder calls in the HTMLGenerator105 component to generate an XML, XHTML, or HTML Web DataWindow.

You specify the type of generation in the DataWindow design-time control by selecting the DataWindow (JSP) in the Page tab, right-clicking the design-time control, and selecting Sybase Web DataWindow DTC 10.5 Properties:

Then in the HTML Generator tab, you select the generation format—HTML, XHTML, or XML:

For example, here the selected generation format is XML. This results in the generation of separate content (XML), layout (XSLT), and style (CSS), and a resulting transformation to XHTML. Setting the Generation Format property to XML is required for the XML Web DataWindow.

Also specify the rows per page for the XML or XHTML DataWindow For optimal bandwidth savings when you use XML or XHTML as the generation format, you must also specify the rows per page in the Control tab.
