You need to provide bigger code sample to be able to even start guessing what the problem might be. - InitK

This is the most generic error you can find working with rdlc.

You have to catch the Exception and give a look at the various levels of InnerException; i.e.:

ex.Message
ex.InnerException.Message
ex.InnerException.InnerException.Message

Maybe try to allow null the parameter you have,

i think you are sending a nothing value on that parameter and your parameter is not design to accept null value, so error will occur. if the problem still there, try to add screen shot
