I have a bunch of reports in my application, all of which display the group tree - however, this is empty in all cases. It is fairly easy for the users to turn it off themselves, but I wanted to disable it programatically as it is never used. How is this done?

Thanks

If the reports never require a group tree, you can change the reports by choosing the File ... report options and untick create group tree (this is using Crystal Reports itself not an add on to the .net environment)

You can also set the properties of the reportviewer, showgrouptree.

One bug i have noticed if you allow the user to toggle the group tree on/off i seem to get the group tree back after the pge has been navigated (if the report is show in multiple pages)

HTH,
