Re-Running Query

Presumably, an RDL data set is only queried once before generating a report. And presumably, this is true even if the data set feeds a list control. However, I'd like to know if I can cause a data set to be queried repeatedly from a list control. I need to do this, because the data set contains aggregate functions that would be impacted by each "pass" the list control would make.

Is it possible to make a data set queried repeatedly in this fashion?

What list control, what environment, what event of the control are you looking to handle here?

IAC "presumably" you want to change a parameter to the report based on the currently-selected item or items in this list, right?

You re-send the parameters and (usually) call ReportRefresh()... but it is hard to say exactly without, um, presuming too much about your scenario <s>.
