2)using dataset i will get whole table.. if my stored proc has 2 queries then i will get 2 tables within same dataset.. i can reference therese using ds.tables(0).rows(value).
3)suppose i use a datareader then i will get multiple-rows. i want to know how to get these each separate rows coloumn values into variables. below is the reader aspx.vb
reader = cmd.ExecuteReader();
while (reader.Read()) {
4)what is it mean by data reader is forward only method of getting data.

I need to do parallel processing in my coding because i have 4 sql to fetch data from database which each take me 3-4 minutes.All the tables involved are raw table and that is no way i can reduce the time for the sql.I need to find a way out to reduce the data fetching time.The only thing i canfigure out is to have this 4 sql execute at the same time by doing parallel processing.

I have two databases (DB1 & DB2) from which i wish to build a single table/gridview output, ideally i want to be able to sort the table by using any data.
However i cannot seem to figure out how to have more than one datasource per Gridview, and if i have more than one Gridviews then i can't sort all the data by any of the columns.
This is a oneway street, i do not want to update the databases from the webfront end.

I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
