Can someone redirect me to your own blog link or any other link explaining complete tutorial about how to implement gridview custom paging using stored procedure?
My search in google giving me old articles from year 2006. Right now I am using asp.net 3.5 and c#.

only finished the cust results before I moved on to another project I was using linq at the time but this might help you understand what is needed to get a gridview going. this is using linq with AdventureWorks as a sample database
Explanation of code now what you need to pay attention to is the
<asp:GridView ID="gdvCust" runat="server" AllowPaging="True"
AutoGenerateColumns="False"
onpageindexchanging="gdvCust_PageIndexChanging">
and the columns and bound fields on the aspx page where DataField = Name of column in database and the Header field is what is labeled at the top of the column on the gridview.
now on the code behind look at
private void GetCustResults()
{
_conResults = CreateCustQuery();
gdvCust.DataSource = _conResults;
gdvCust.DataBind();
}
//and
protected void gdvCust_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gdvCust.PageIndex = e.NewPageIndex;
gdvCust.DataSource = _conResults;
gdvCust.DataBind();
}
they do the binding from a data source and the paging control. comment if you need some more explaination
Check the code below.
CREATE PROCEDURE getDeals
@StartIndex int,
@PageSize int,
@TotalCount int OutPut
as
select @TotalCount=count(1) from mstrDeals;
WITH CTE AS
(
select top(@startIndex+@PageSize-1) ROW_NUMBER() OVER(ORDER BY creationdate) RowNumber,dealid,dealTitle from mstrDeals
)
select * from CTE where RowNumber between @startIndex and (@startIndex+@PageSize-1)
Then we need to generate pager with total no of rows, page size and current page, below is the sample code that populating pager here total number of pager links is 5 that can be customize further by resetting local variable named totalLinkInPage and have first and last button also which automatic enable or disable when current page is first or last accordingly.
Check out generate pagination code and bind gridview code (reference):-
Custom paging in asp.net using stored procedure in gridview with nice pagination
Since SQL's syntax hasn't changes much since 2006, there isn't much to update. On the stored procedure side you would still do a ROW_Number() call.
With table AS
( SELECT ID, NAME,
ROW_NUMBER() OVER (order by Name) as RowNumber
FROM Customers )
select *
from table
Where RowNumber >= @RowStart and RowNumber <= @RowEnd end
