The best way to log access to SSRS reports

The correct answer would be to say yes - however, a quick win is to close your solution, then open the .rdl file up with notepad and do a find-and-replace. Then save your .rdl file and re-open your solution - you should find all of your references within the report have been updated. Remember that the .rdl file is essentially an xml file, open it up and have a look around - it will help you understand the inner workings better. You will of course need to update the data source yourself though.

I hope this helps you.

As it looked ok in design mode and the issue was happening at run time, it would be helpful to investigate what elements displayed in the Tablix can grow or expand at run time.

I resolved this issue by following the steps below:

1- There was an image in one of the tablixe cells, I checked to see what is the selected option for displaying the image, if its size is bigger than the cell's size. The image had set to accept the growth, so it was increasing the width of the cell and consequently the Tablix size.

2- The padding for all cells of the row needs to be checked, especially it can be simply overlooked when an image has been assigned to a cell in the Tablix. If there is a padding, it would affect the cell size and eventually the row size in the Tablix.

I hope this description helps anyone else experience this issue.
