Create Dynamic columns in an RDLC report

Hi,

I need to create dynamic queries using RDLC. My column names come from a query:

Select distinct item_Number from item_Table

The output should appear as columns like:

Store   |   Location   |  ItemNumber1  |  ItemNumber2  |  ItemNumber3  |.....|Total

How can I set this in my RDLC. I need totals inside the column names for this report. eg:

Store   |   Location   |  ItemNumber1  |  ItemNumber2  |  ItemNumber3  |.....|Total

111      |  NY            |   28                 |  30                   |  2                    |.....|

How can I do this. Please help me with a process. Till now I have used typed dataset. Can I use any other process.
