i have to set a show condition on an Upload-Button only if a file is selected in the File Browser Item in the same Region..
The Upload-Button should not be visible, if a File is not selected.
Is it possible?
What version APEX are you on? If 4.x, then you can define a dynamic action onChange of the file browse item with a condition testing if it's null, then relevant true/false actions to show/hide your button.
Thanks for your answer...
Yes, it is Apex 4.1 and i already have tested it with an dynamic action. The Problem is, that the Buttion is a "region-button" and this item can't be selected in the Dynamic Action menu.
Is there a possibility to use Region Buttons with Dynamic Actions?
Yes, but if memory serves correct you need to ensure your button template has an ID, typically something like
The DA uses this to identify the button. Templates have been improved as time goes on...
Do you habe an example on http://apex.oracle.com/pls/apex/?
apex.oracle.com is now on 4.2.3, which has none of the button/DA problems 4.1 has.
Try "html button" style, or check the template you're using.
