I have a page setup where I would like to hide an imagebutton when the user starts their upload. The only function that even allows me to manipulate the imagebutton is on fileuploaded. Which is useful for showing it again, but I cant hide it on uploading.

 

I tried all the other options such as (AttachmentActionClicked,AttachmentAdded,AttachmentCreated,AttachmentDataBound) etc.. None of them will allow me to do this.

 

I figured if you had an OnClientClick functionality, I could create by own postback in a javascript function to handle it.

 

What are my options?

 

I want to add I am using the autoupload option if this helps.
