Export To Excel, CSV, XML with expression in Hidden property omits data

I have a matrix table with a rectangle in the data cell. The rectangle has an image and textbox. The textbox has an expression in it's Hidden property based on the column name. The report renders fine on screen. When the report is exported to Excel, CSV, XML the textbox contents are not output (the images display as expected). I've tried setting the DataElementOutput to Output/Yes with no success. Exporting to TIFF, PDF, Web Archive/MTHML is fine.

Here is a sample RDL which exhibits the issue:

Here is a posting related to this that may help.

Andrew,

Thanks for the posting. I've seen that blog. Unfortunately, the "good news" wasn't so good for this case. The setting of DataElementOutput(yes, no, auto) has no effect on the output for the situation described . If you find any other possibilities I would very much appreciate it.

Thanks,

Brian
