I have an ssrs report with a tablix on it. There is one group with a group header row. I merged the cells on that row and set the textbox border color to black. The column associated with that group now has black border instead of the default light gray, which is fine. I'm trying to set the other textboxes in the details row to border color black. It won't stick. I hit OK and it's still light gray. I go back and it says light gray. I switch to black, hit OK and again, it's light gray. What am I doing wrong? How can I get it to "stick"? Thanks.
