Look up subreports in the SSRS documentation. Subreports allows you to embed
one report inside another. That may be what you want. Watch out though -
subreporting is not very flexible and has lots of limitations. The two most
frustrating are scheduled execution becomes very complex to manage and there
is no simple way to pass variables up or down the chain.

If all you want to do is put more than one table/chart/matrix on the screen
at once you may be better off just creating multiple datasets and chart
objects inside the same report.

What you need to do is to bring all the data of all the controls say Table,
chart, matrix etc.. with different dataset keeping one record of all
information in each datasets. so that it doesn't iterate for the records.
This way you can achieve Dashboard at one short.
