Ascx transformation questions

The field where you are storing the image is holding just the GUID of the attachment form the CMS_Attachment table. So, you can also compose the URL manually to look like ~/getattachment/

Thank you. You mean to hardcode part of url in transormations, like this: <image>cms/getattachments/<%# Eval("Thumbnail") %></image>

if so, how can I get an image filename by it's guid?

Can you also check second part of my question, about categories?

I would recommend using one of the transformation methods for images. And for the categories - there is no ASCX transformation method available - the one you used looks more like a macro, which is not supported in ASCX transformations. I would rather recommend creating a custom transformation and use the API to achieve your need.

Thank you.

The problem with transformation methods for images is that they returns the whole image tag, while i need just a link. Can I use something(like regex or smth else) to extract the link from tag code? Also, transformation method GetImage doesn't include the localhost's port to image link, so it becomes <img alt="" src="http://localhost/getattachment/bd9127f3-7ef4-4dd8-ab51-8cf951c0a3b7/rss-1.aspx"/> instead of <img alt="" src="http://localhost:8066/getattachment/bd9127f3-7ef4-4dd8-ab51-8cf951c0a3b7/rss-1.aspx"/> May be the problem won't reproduce when deployed not on localhost, but however it looks suspisious.

I'll also try your advice for categories, thank you.

The port number is added probably because you are running the project from Visual studio. When running on full IIS, this won't be a problem. And for getting just links, you can use the page and URL methods like GetAttachmetUrl or there are few more options.
