Retrieve value from stored procedure as dataset and add to datatable

Question

Hi,I have declared a datatable that is somehow similar to the table in the database.

 

DataTable dtgvCriticalTerms = null; //Reflect the CT table in SQL 
Server 



dtgvCriticalTerms = vrmdb.Get_CriticalTerms("ContractID").Tables[0];

Since the query string is ContractID, is my next step needs to declare a dataset such that it can store the data associated with this table?

Once i have this dataset, i need to add it back to the datatable that i have defined it early before?
is it made use of this code:

 

dtgvCriticalTerms = ViewState[viewStateGVCTName] as DataTable;

Thks!
