SitemapGenerator: Ecommerce products are not included in the sitemap

Sitefinity sitemap generator is cool, but you get frustrated when it won't do what it was build for ... And you have to vote for the bug and wait for it to be fixed in the next release or next to that next, so on., You can see & vote the bug logged in their feedback tool.

Well., that is not the end of the story. Even though I blame them for such obvious reasons, I love their Sitefinity product. It is such extensible and provides/exposes various events for most built in modules through Event Hub. You can subscribe to this events and implement your requirements in a Jiff.

So for Sitemap Generator, I could hook to ISitemapGeneratorBeforeWriting and fix the bug on my own till the official fix is released for this version OR may be the next version(Forced to upgrade for a fix).

Following code in global.ascx, will help you add the missing dynamic pages to sitemap
