Description

The methods listed in this section are now supported by server-side Web DataWindow objects. The Web DataWindow was formerly known as the HTML DataWindow.

It is also possible to call some of these methods in client-side scripts on the Web DataWindow client control. The description for each method in the DataWindow Reference indicates the type of DataWindow to which it applies.

Usage

When you place a Web DataWindow DTC onto a 4GL Web page, you create an object of type PSWebDataWindowClass on the application server. This object has its own server-side events and methods. Server-side methods are listed below. For information on server-side events, see New Web DataWindow events.

The Web DataWindow server component resides on a component server. When you install EAServer, a default DataWindow server component is provided for you. The methods that apply to the default server component are defined in an interface definition file (HTMLGenerator80.idl). If you are using a Web DataWindow DTC and the Web Target object model, you would not call these methods directly, but would use the methods defined for objects of type PSWebDataWindowClass.

You can also create a custom DataWindow server component with its own server-side methods.

The syntax you use, including the data types of method arguments, depends on the object type or DataWindow control on which you call the method. Methods of the Web DataWindow server component with more than one syntax have different names to overcome restrictions on the use of overloading. These name variations are listed under the main method name (for example, ClearValuesByColNum is listed under the ClearValues method).
