Paging in my web page - asp.net

Question

I have a large data set and i have to apply paging on that data set and after that the result set should be another data set. What is the reliable method to achieve that.
I have tried with 'PagedDataSource' class but i don't know how it is possible to convert to dataset or data table.
In my case i need a general solution. I have to bind to a control like gridview as well as i have to used it with normal html table.

check this article doing same thing you want : http://www.codeproject.com/KB/custom-controls/EnhanceGrid.aspx
following sp returns record that you want
CREATE PROCEDURE [dbo].[GetRequestedRecordByPage]
#FromList nvarchar(200) -- Table Name
,#SortingCol nvarchar(200) -- Sorting column Name
,#SelectList nvarchar(200) = '*' -- Select columns list
,#WhereClause nvarchar(200) = '' -- Where clause i.e condition
,#PageNum int = 1 -- Requested page number
,#PageSize int = 5 -- No of record in page
,#TotalNoOfRecord int output -- Total no of selected records
AS
Begin
SET NOCOUNT ON
DECLARE #Query nvarchar(max) -- query going to be execute
IF rtrim(ltrim(#WhereClause)) <> ''
BEGIN
SET #Query ='SELECT #TotalNoOfRecord = COUNT(*)
FROM ' + #FromList + '
WHERE ' + #WhereClause
END
ELSE
BEGIN
SET #Query ='SELECT #TotalNoOfRecord = COUNT(*)
FROM ' + #FromList
END
/* Count no. of record */
EXEC sp_executeSQL
#Query,
#params = N'#TotalNoOfRecord INT OUTPUT',
= #TotalNoOfRecord OUTPUT
DECLARE #lbound int, #ubound int
/* Calculating upper and lower bound */
SET #lbound = ((#PageNum - 1) * #PageSize)
SET #ubound = #lbound + #PageSize + 1
/* Get list of record(s) */
SELECT #Query = ''
SELECT #Query = 'SELECT *
FROM (
SELECT ROW_NUMBER() OVER(ORDER BY ' + #SortingCol + ') AS rownumber,' +#SelectList +
' FROM ' + #FromList
IF rtrim(ltrim(#WhereClause)) <> ''
BEGIN
SELECT #Query = #Query + ' WHERE ' + #WhereClause
END
SELECT #Query = #Query + ' ) AS tbl
WHERE rownumber > ' + CONVERT(varchar(9), #lbound) +
' AND rownumber < ' + CONVERT(varchar(9), #ubound)
EXEC (#Query)
End
