I have created an SSRS 2008 report with a data-driven list of hyperlinks. The hyperlinks work fine in the VS2008 designer/preview window, but when they are deployed to the Report Manager and viewed in IE8 the hyperlinks do not jump anywhere despite having the cursor change to the pointing hand icon on mouseover. The complete hyperlink, including "http://", plus the visible textbox value and the tooltip all come from the database via stored procedure call.
While troubleshooting, I found that a) the data-driven hyperlinks do not include an anchor tag element in the report page source (the reason for the bug), and b) non-data-driven hyperlinks work fine even in the browser.
The hyperlink list is included in a tablix control in the report body section which is displayed after the tablix containing the main report data.
I have SQL Server 2008 SP1 and cumulative update 7 for SP1.
