convert rows to columns c#

[nihirshah]

I have a grid in dataset as following

UserPatientStatusID RelevantPeriod TotalCount ProviderSpecialtyServiceName
a OUT November2008 1 Not Available
a ER September2008 1986 Not Available

c OUT April2009 1 Not Available

c ER March2009 1931 Not Available
c REC August2009 1 Not Available

I know that there can be 24 relevant periods for each user. There may or may not be all 24 present for each user.

Now all that 24 periods I have in an array in C#. I know what these periods will be. They change so I cannot hardcode it. It has to be dynamic.

I want to create 24 columns of that rows for relevant periods and display TotalCount in that and get all other data accordingly in c#.

Please advise me or show me some sample code.

Thanks in advance
