OK , can't you add a DataSet.xsd and do the same thing I have mensioned above and try out the work , doing experiments are good too

ok i try to explain again

i want create from code new rdlc.
i dont create any database and i dont want create.

i want after create rdlc add table and fill table with list data

The details are very less in the questions you have posted , but can't you populate a dataset from the List you have mensioned and use that dataset to a report
