if you want to bind/associate image details on data bound event, you need to do following,
step 1. Identify the layout controls inside the repeater. Say if you have a Table layout which is repeating for each row of data source. You need to capture that in that data bound event handler. (To do that you might need to add a runat = server in case of a table layout )
step 2. Once the layout control is identified, find the image control ( assuming that in aspx file you must have provided an image control inside layout to display the images). Then set required property of that images.
NB: Row Bound event handler's event argument should give you the data from database i.e image title, image path etc.
Please let me know if you need more help.

If you're going to ask in the Quick Questions, don't cross post here. And if you're using ASP.NET, you didn't say so before, although I guess it's irrelevant ( and therefore the question does not belong here, if you're using ASP.NET or not )

I am having a global resource file in the App_GlobalResources folder.
In that I have included my JS file.
Also it is in the web applicaiton also.
In the run time I want to load the js based on the resource file selected in the page and to register the events for the buttone.
Kindly help me how to do it.
Thanks a lot in advance.

When you add resource in the resource file in a web application it doesn’t get marked with the WebResource attribute, it means that you can not access this on the basis of the ui culture using a resource manager. This is more appropriate for control development. I suggest you to manually load the js file on the basis of the ui culture. Instead of embedding the js file in global resource, place them in a separate folder and load them accordingly.

Dear Prakash,
Thank your for your hint.
Can you tell me how to load the JS dynamically by having them in the web application.

Check the Thread.CurrentThread.CurrentCulture.Name and register the script using CleintScript.RegisterClientScriptInclude method like
ClientScript.RegisterClientScriptInclude("MyScript","MyScript.en-GB.js")

Hi,
I am using datalist in c# web application. the site was fast till about I had 2000 records now it slowed down and I need to efficiently page the data rows. I followed this article.
http://aspnet.4guysfromrolla.com/articles/031506-1.aspx
but, it only gives me 10 records at a time but the actual result is ~500000
in my below code
<pre>
List<Advert> adverts = new List<Advert>();
PagedDataSource pds = new PagedDataSource();
pds.AllowPaging = true;
adverts = myBLL.GetAdverts(country, city, adtype,pds.CurrentPageIndex,pds.PageSize);
PropertyListCount = adverts.Count;
pds.DataSource = adverts;
pds.PageSize = 10;
</pre>
I know i am only getting 10 records as its only retrieving 10 records for the firsst time for Page No 1
but how can i display other page numbers so when user clicks Page 2 the parameter becomes
pds.CurrentPageIndex=10 and pds.PageSize=10?
please help I hope my question is clear enough to understand.
thank you

this is exactly what i am doing. its little show. takes about 5secs to display 35000 records. is there something funny i might be doing? or it is normal for it to take 5 secs?
well its queries "select * from table" but this operation might take long?

You should change your query to return only the number of records necessary for the page.

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.

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.
