I had a customer request to hide a row conditionally, but when the report rendered in the browser the hidden row still took up spacing on the report.
I found this post thanks to Frank v.d. Laar:

Try to set the Hidden property of the Static Row Group under the Details Group, in this case the whole row will disappear instead of the content of the textboxes.
If you are using Report Builder, you need to switch to Advanced Mode (make sure that the Properties and the Grouping windows are displayed, go to the upper right side of the Grouping window and press the black triangle), click on the second "Static" item under the "(Details)" group and you can set the Hidden property on the Properties window.


We have a bug/enhancement list we use to show what items have been completed, if they are bugs or enhancement, assignees, etc.
Getting SQL Server 2008 Reporting Services series chart line to start @ 0 (trying to mimic another chart in another application that does the same thing) was a bit of a challenge. The line chart series is being used for accounting and starts at the January amount, say $10,000 for the first month data value.
After much searching to try to get around the division by zero issue, I had to create a custom code function for both the report rendering and interactive column sorting to work.
