I'm gonna go crazy. I'm searching for a simple solution but it seems what I want isn't possible!? I have a Report with Header/Body/Footer. Inside the Body I had an Rectangle, next to an Tablix.
I want that this Rectangle is Auto-Stretched to full size of the body. So from top body to bottom body. The body area is flexible so has no fixed height. How can I achieve this? I tried every property of the rect, but still fail.
Maybe someone has the Solution as I searched 25+ Websites with no result.
