Some supported features increase the size of the generated code. If you do not use a feature such as display formatting, validation rules, or client-side scripting, you can enhance performance by preventing the server component from generating code for the unused feature. You can turn these features on or off on the Web Generation property page in the DataWindow painter or in a script. For more information, see “Controlling what is generated”.
You can also cache client-side methods in JavaScript files to reduce the size of the generated code and increase performance on both the server and the client. Without JavaScript caching, each time a Web DataWindow is rendered in a client browser, JavaScript code for DataWindow methods is generated on the server and downloaded to the client. When you set DataWindow properties to reference cached JavaScript files, the methods defined in the files are not generated with the HTML in any Web DataWindow pages that are sent to the page server (and client browser).
