You define DataWindow objects in PowerBuilder. The Web ActiveX supports all DataWindow presentation styles except RichText.
You can use all edit styles, including DropDownDataWindow. Properties can have conditional expressions (written in PowerScript) and computed fields can use any of the functions available to a standard DataWindow.
In the Web page, you can include scripts (written in JScript or other ECMAScript-compatible scripting languages) to manipulate DataWindow presentation and data.
