How to programatically execute download event

[Former Member]

HELLO.

I want to add download functionality to my web dynnpro app. All examples shows that I must generate ByteArray in the wdInit method. The problem is that it is a lot of files and I dont want to generate them all on view init. I want to generate the byte array after choosing donwload option. How can I achieve it ?

Thanks in advance

ps. there is no option to set onAction on download file component. it autommatically download binded ByteArray

without possibility to execute any line of code before it.

Hi,

create a button or link and add the following code to its action handler:

final byte[] data = ...;
final IWDCachedWebResource resource = WDWebResource.getWebResource(data, WDWebResourceType.<MIME_TYPE>);
try {
	final IWDWindow window = wdComponentAPI.getWindowManager().createExternalWindow(resource.getAbsoluteURL(), "Title", false);
	window.open();
} catch(Exception e) {
	wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);
}
