Multiple Sub Report

[ahmad_hamdan]

I have the following a Master Table that has some Id and a child table with multiple records for that Id, i created a Main rdlc report in asp.net and a sub report, i am having trouble on displaying the sub report as multiple times (i.e. for reach record in the child table for a particular Main Id there should be a sub report with the information related to the child tabke), i was able to display it repeated but it repeated the first record of the child table.

So can any one point me to the right way to do the above?
