A very quick note on why borders may be misbehaving in SSRS. This note corrects the situation at Design time. This is where you are trying to select a cell to have an outline border but then cells around it without a border. You may find that BIDS or Report Builder (however you're building your report) will apply the border to some cells and sometimes a whole section of the report with just one border???
How?
- In Design view, click on the first cell (top-left),
- hold down the shift key
- and click on the last cell (bottom-right). This selects all cells.
- Now open the "Properties" pane,
- find the "BorderStyle"
- and type the word "None" next to it (as its value).
- Press the "Enter" key if you need to.
You are now free to apply normal borders to each specific cell.
