Hi all, I've encountered a weird issue when i deploy one report on my report server. There is a tablix in my report, and it has two groups, one is group1,the other is detail, i set the detail was toggled by the group1's head row. If i select the "Do not cache temporary copies of this report" option in execution tab in report manager, then it is ok ,the group1's head row could toggle detail row correctly, but after i select the "Cache a temporary copy of the report. Expire copy of report after a number of minutes:10" option, there a problem occured, when i click the toggle icon at first time ,the detail row wouldn't show, but after that, the toggle works correctly, in other words, only the first time the toggle can not work. In order to prove that, i reset the the cache option to do not cache the report, and the toggle works fine no matter first time or after that. Can anybody help me, any reply would be appreciated aaron

Hi, It works fine in my enviroment. So could you please check the specific version of your Reporting Services, it can be found at the bottom of the Report Server page.
