Hello,

Thank you for your message. The CMSUploader control was specifically created for use with BizForm/KentiForm engine (that's why it isn't documented in detail, it's only described in the API Reference). If you need to create an upload field in your custom form, I would rather recommend you creating a standard upload dialog.

Best Regards,

Hello,
I'm working now on the simillary thing, I made component(ascx control) for automaticaly created multipaged form based on BizForm with using all funcionality of it(rendering, validation, mail sending etc.). Everething is ok, but just only CMSUploader is not working properly, it is due to specification of used html control <input type=file/>, it's not problem of CMSUploader. It's principaly impossible to use this control thru more postbacks without own handling of uploaded files, because they are contained only in the request from "form/page" where the control was rendered. Try to read something about http file posting. You must keep them "anywhere" after postback from "form/page" with upload control and "manualy" use them in final request processing.
I found just one way to do that, don't use standard CMSUploader(for error throwing) and use own component which know to do specified above. But first question is "How to implement your own component(ascx control) to BizForm?". It's easy if your are familiar with standard Kentico CMSForms. If you don't know how to do that, write this and I can write some simple article in this forum about how to do that in the concrete...
I hope that my answer is understandable, sorry for my english:)
