Collapse all details in SSRS 2005 report?

Hello,

I have a report that contains a single group for customers. Each customer order is placed as a detail record under the group. I have the group header setup to toggle the detail records (so if a user clicks the plus sign image, the details are shown, if the user clicks the minus image, the details are hidden). By default when the report opens up the details are shown.

Rather than having the user click through each customer row to collapse all the details, is it possible to place a "collapse all" image or control somewhere on the report that will handle the collapsing of all the detail rows for each customer record? I assume if there is a way, there is something similar for expanding all as well?

Thanks!

The "initial state" of toggles on groups can be determined by expressions. You could add e.g. a boolean report parameter and then set the initial toggle state of all toggles to be based on the report parameter value.
