im working on a report which shows the data based on the users input. I have used a matrix because I have no control on how many fields the users want, so practically we have a dynamic column here. My problem is that they require me to able the user to hide the columns he/she wishes to during runtime. We have a previous report that enables the user to hide it during runtime but it has static column. Any idea on how I could do it?... Thank you so much... By the way im using microsoft reporting services...
