Thanks for your replay,,
Let me explain clearly,,,actually we are implementing a dashboard the first page is like this....
--Middleware(these all are not the tabs its like a tree structure, and assume all are individual sheets)
From this first page if i click servers that report has display and if i click on Desktops that report has to display ....... i think now you understand my req...
So you can use the Show Condition in the the individual sheets.
Choose Sheet properties -> Layout -> Show -> Conditinal
In the Conditional window you can use something like:
That will for e.g. show your Hardware-Sheet if there is "Hardware" selected in the field where you have your tree information.
Is that what you need?
