Sorting data in SSRS report .

I initially have a report and it uses RDP class to populate data in the report.The data for temporary table gets populated through various tables across many classes and It doesn’t uses Query concept to loop through the required records.There is a field called surchage field in temporary table and I need to sort that field .How to sort the data after data gets inserted in Temporary table and also how to perform this through code level?

Look at Sort Data in a Data Region (Report Builder and SSRS)
