create "expand all" button.
Is there a built in option of adding an Expand/Collapse all Button to my report?
I have a report with few groups and I want to give the user a simple way to expand all of them for easy view or collapse all of them so he can see only the groups header.
I thought about using an expression in the hidden property of the groups and try to control it with parameters but its looks like a lot of work.
I also predict problem with it if I'll try to sort the table and the page will refresh it self every time.
Is there something "of the self" for it?
