I tried that too. it returns 10 record and there is no page 2 or 3
below is the query
SELECT *
FROM
(SELECT *,
ROW_NUMBER() OVER(ORDER BY adid) as RowNum
FROM advert e
) as DerivedTableName
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1

There are a lot of articles that cover datalist paging, like this one[^] or this one[^]

Hi again, this article http://aspalliance.com/157_Paging_in_DataList was someway useful but I have already done that part and it mentions the disadvantage at the end of the article too..
so I changed my database call to add extra parameter i.e. currentindex and total rec to display per page
<pre>
public void AdList(Navigation navigation)
{
List<Advert> adverts = new List<Advert>();
PagedDataSource pds = new PagedDataSource();
pds.AllowPaging = true;
//Based on navigation manage the NowViewing
switch (navigation)
{
case Navigation.Next: //Increment NowViewing by 1
NowViewing++;
break;
case Navigation.Previous: //Decrement NowViewing by 1
NowViewing--;
break;
case Navigation.Last: //Make NowViewing to last page for PagedDataSource
NowViewing = pds.PageCount - 1;
break;
default: //Default NowViewing set to 0
NowViewing = 0;
break;
}
adverts = myBLL.GetAdverts(country, city, adtype,NowViewing,pds.PageSize);
PropertyListCount = adverts.Count;
pds.DataSource = adverts;
pds.PageSize = 10;
//Set the current page index
pds.CurrentPageIndex = NowViewing;
// Disable Prev, Next, First, Last buttons if necessary
lbtnPrev.Enabled = !pds.IsFirstPage;
lbtnNext.Enabled = !pds.IsLastPage;
lbtnFirst.Enabled = !pds.IsFirstPage;
lbtnLast.Enabled = !pds.IsLastPage;
dlPropertyList.DataSource = pds;
dlPropertyList.DataBind();
}
//DataList Pagination Scripts
protected void lbtnPrev_Click(object sender, EventArgs e)
{
PropertyList(Navigation.Previous);
}
protected void lbtnNext_Click(object sender, EventArgs e)
{
PropertyList(Navigation.Next);
}
protected void lbtnFirst_Click(object sender, EventArgs e)
{
PropertyList(Navigation.First);
}
protected void lbtnLast_Click(object sender, EventArgs e)
{
PropertyList(Navigation.Last);
}
public enum Navigation
{
None,
First,
Next,
Previous,
Last,
Pager
}
public int NowViewing
{
get
{
object obj = ViewState["_NowViewing"];
if (obj == null)
return 0;
else
return (int)obj;
}
set
{
this.ViewState["_NowViewing"] = value;
}
}
---STORED proc script
select ROW_NUMBER() OVER(ORDER BY adid) as RowNum,
* from advert where isActive=1 and
c.countryname like '%'+@CountryName+'%' and
a.adcity like '%'+@AdCity+'%' and
a.AdSubCatType like '%'+@AdSubCatType+'%'
) as DerivedTableName
WHERE RowNum BETWEEN @CurrentPageIndex AND (@CurrentPageIndex + @PageSize) - 1
order by adDate desc
</pre>
but this gives only 10 records in one call so how can i display total records, next and previous etc?

can someone please help me. I need a fastest way to display datalist with hugh record set in website.

You might try MultiThreading here. Each thread would pull 'n' number of record set from database. Hence if you are having 2 thread for pulling data from database your performance is doubled. Currently if 35000 record is fetched in 5 seconds, then if you use 2 thread for data pulling then you could get 70000 records pulled from database in same 5 seconds.
But the risk is that correct multithreading can provide you very enhanced reformance, whereas if not implemented correctly it can lead to severely affecting the exising system.
Thanks,

I am sure there must be an alternative solutions other than multi-threading. I saw this article http://www.netomatix.com/Development/DataListPaging.aspx in this article it users query string but how can i use it without having to use querystring
could someone please help? I now have created two stored proc one returns the total count of the result which is about 35000 and the one to display for a page currently being views i.e.
adverts = myBLL.GetAdverts(country, city, adtype,NowViewing,pds.PageSize);
-SQL
SELECT *
FROM
(
select ROW_NUMBER() OVER(ORDER BY adid) as RowNum,
a.*
from advert
where isActive=1 and
c.countryname like '%'+@CountryName+'%' and
a.adcity like '%'+@AdCity+'%' and
a.AdSubCatType like '%'+@AdSubCatType+'%'
) as DerivedTableName
WHERE RowNum BETWEEN @CurrentPageIndex AND (@CurrentPageIndex + @PageSize) - 1
order by adDate desc

hey. am new in asp.net. Actually, I have a series of component and would like these component come invisible before.although I invisible the properties, I need to make them invisible before loading page. I am lloking for sth like page load but don't know when and where to write it.
thx for ur help in advance

Your post isn't exactly clear. If you set the visibility property of the control it will be not be visible when the page loads.

I have an ASP page, and want to have a hover changing style event.
Here is the code for the hyperlink.
<asp:HyperLink ID="HyperLink1" runat="server" BorderStyle="None"
Font-Underline="False" NavigateUrl="~/Default.aspx"
ToolTip="See Overview of Cardington Site">
Cardington</asp:HyperLink>
I was thinking there is a way of doing a StaticHoverStyle, but I think I can only do that in a MENU item.
Is there a way of doing a mouse over change easily?
PS Using VB as code behind.

Just add the events to the link
<asp:HyperLink ID="HyperLink1" runat="server" BorderStyle="None"
Font-Underline="False" NavigateUrl="~/Default.aspx"
ToolTip="See Overview of Cardington Site"
onmouseover=MouseOverFunction onmouseout=MouseOutFunction>
Cardington</asp:HyperLink>

<asp:HyperLink ID="HyperLink1" runat="server" BorderStyle="None"
Font-Underline="False" NavigateUrl="~/Default.aspx"
ToolTip="See Overview of Cardington Site"
onmouseover = bgcolor="Red" onmouseout = bgColor="Aqua">
Cardington</asp:HyperLink>
I put this line in but it is not a happy bunny.
It is suggesting that if this statement contains quotes, then they must match, but they do.
When I build it fails
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Of course its not happy, that is not the correct syntax. 
onmouseover="this.style.bgcolor='Red'" onmouseout="this.style.bgcolor='Aqua'"

Ah, got it!
onmouseover="this.style.color='red'" onmouseout="this.style.color='black'"
Your answer was superb, it got me thinking, got me searching and the final solution was down to me working on your response!
I feel all clever with myself, as I am not an ASP expert!
(obviously).
Thanks, have a vote-up.

Good although if all you are doing is setting styles a better way to handle this would be to use CSS
<style>
.MouseOver:hover
{
color:Red;
}
.MouseOver
{
color: Black;
}
</style>
<asp:HyperLink ID="HyperLink1" runat="server" BorderStyle="None"
Font-Underline="False" NavigateUrl="~/Default.aspx"
ToolTip="See Overview of Cardington Site" CssClass="MouseOver">
Cardington</asp:HyperLink>

Cheers, I find the more I do, the more I find out what I don't know, and the more I have to ask.
I am getting such an education on this site.
And BTW, thanks for the swift replies.

Could you link to screenshots of your application's setup within IIS please?
|
|
|
|
|
Try opening IIS. Expand the Treeview that contains all sites/sub directories etc. Look for the virtual directory called "myapp" (or whatever you've named your site). Right click ->Properties. Under the Directory tab, click the button that says "Create" (which is inside the Application Settings group) then click OK.
Hope that helps...

Hi experts
I have googled for tips/solutions and failed to get a right method to implement following scenario.
I have a gridview populated with data on page load from my source table.
To make it precise I have fields Ac_Id, Ac_Name, Balance, and user_Id in my table. The user_Id and Ac_Id forms the composite key.
I have say 3 rows in my table as follows
1, Cash, 1000, ABC
2. CITI, 8000, ABC
3. BOA , 6000, ABC
While editing in grid I want let user edit only the balance field if Ac_Name is Cash otherwise User can Edit both Ac_Name and Balance.
whle I could make both ac_name and Balance field editable but failed to achive above. Advise is solicited
Thanks in advance and regards
Kris

Hello!
When I try to built my web project I get the following error: "A namespace does not directly contain members such as fields or methods" for a file called 'DownloadFiles.aspx' (which has also an code behind file). The error should be in lone 1 row 1.
<%@Page Language="C#" AutoEventWireup="true" CodeFile="DownloadFiles.aspx.cs"
Inherits="MD.TPConfigurator.Web.DownloadFiles"
Culture="auto" UICulture="auto" Async="true" %>
<html>
<head>
<title>Download</title>
</head>
<body>
</body>
</html>
The funny thing is, when I open the file 'DownloadFiles.aspx' and try to build it again, there is no error any more. I am also sure that there are no members directly in the namespace.
Has anyone any ideas?
Thanks in advance,
Florian
