Conditionally Show/Hide or Enable/Disable an option in a radio button list

This would be best handled with JavaScript. Doing this with server side code would mean you'd have to create a custom form control.

Thanks very much Brenden for your response!

Is there any way to get the uploaded file extension before saving the form and use same extension in some other field via macro?

Thanks,

I agree with Brenden, using Javascript you should be able to simply read the textbox of the Upload control (which depending on which one, should show the file path, including the file extension) and do a show/hide.

If you wanted to do it server side, I don’t believe there is anyway by default to grab that value using macros. If you wanted to do it, this is what you would have to do:

1. Create or clone the Upload File form control
2. Modify the “File Select” portion of that upload form control, to trigger when they select a file (there may already be a hook or event for this)
3. Use the MacroContext.CurrentResolver.SetNamedSourceData(“TheUploadExtension”, TheUploadExtensionValue);
4. Leverage that in your visible field (ex: {% TheUploadExtension == “pdf” %})

Hope that helps!

May be my question is silly but just wanted to be more clear.

We have created a custom uploader inside which we are using Kentico's Direct Uploader itself (~\CMSModules\Content\Controls\Attachments\DocumentAttachments\DirectUploader.ascx) and the extra thing which we included in this is a preview option of the file.

After this, we have a document type called "File Attachment" in which one of the field is "File" to which the above mentioned custom form control is assigned.

Now we've recently added a radio button list in the document type itself from Kentico UI which has three options:

1. Sidebar

2. Embed

3. Inline

Now, on the basis of selected file extension (before saving it to DB), we need to show/hide "Embed" option where I'm stuck. As per my understanding from various posts, we can assign the source to radio button list with some conditions as well using macro but before that I need to get the file extension.

And to do same with javascript, I'm confused to how get the new file upload event and the update file event (inside a grid in direct uploader) where I need to fetch the file extension and show/hide the "Embed" option in radio button list.

Waiting for your help now!

Javascript will definitely be easier in this case. It still is possible to do it my way, where you add stuff to the current Macro Resolver, but it's a lot of work just to get that.
