Retrieve data tables from database with stored procedure - asp.net

Question

Let me explain you in details the scenario that I am having and the solution I am looking for.
Firstfully, I created a stored procedure that outputs simple things such as 2 tables and a message 'don't stop here'"
T-SQL:
USE [mydb]
GO
/****** Object: StoredProcedure [dbo].[BackupDatabase] Script Date: 2/26/2013 11:29:10 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create PROCEDURE [dbo].[testing]
AS
BEGIN
select 'A' firstname, 'B' lastname;
print 'dont stop here'
select 1 final
END
Up until now I used to retriew the tables in a single manner by using datarowcollection class, and my static method looked like this:
C#:
public static class DataMan
{
public static DataRowCollection SelectData(string sql)
{
SqlDataSource DS = new SqlDataSource(CS, sql);
return ((DataView)DS.Select(DataSourceSelectArguments.Empty)).ToTable().Rows;
}
public static string CS = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
}
where I can easily get what i needed like here, and locate what evver row I wanted:
DataRowCollection people = Util.SelectData("Select * from students")
But now I am planning to create a stored procedure Like I mentioned above and do somthing like this, for instance:
**DataTableCollection** people = Util.SelectData("exec dbo.Testing")
UPDATE:
so I can locate the specific table from my storedprocedure.
I have tried to use DataTable, DataSet, DataTableCollections but no success.I can't use them in proper way.
Please help me
Thank You

Although it can be used in code-behind as you're illustrating here, the SqlDataSource is more typically used in a declarative manner on an ASP.NET markup page. However, given what you've started, when calling a stored procedure, you should set the SqlCommandType to StoredProcedure, supply the name of the procedure to SelectCommand, and return a DataReader. The DataReader, in turn, supports a NextResult() method that you can call to retrieve each discrete result set your procedure provides. Here is a framework of pseudo code that tries to illustrate how you might leverage this:
// pseudo code
void stub()
{
SqlDataSource d = new SqlDataSource(*connection string*);
d.DataSourceMode = SqlDataSourceMode.DataReader;
d.SelectCommandType = SqlDataSourceCommandType.StoredProcedure;
d.SelectCommand = "dbo.Testing";
// set some parameters
d.SelectParameters.Add("Parameter1Name","Parameter1Value"); // must be tailored to your proc!!
d.SelectParameters.Add("Parameter2Name","Parameter2Value"); // must be tailored to SqlDataReader r = (SqlDataReader) d.Select();
while (r.HasRows)
{
while (r.Read())
{
// do something with each row
}
// advance to next result set
r.NextResult();
}
r.Close();
}
