Normally the only reason why something would be kicked out of the cache before the expiration time is because the web site needed more memory so it would expire the cache before its time. NOTE you are using an absolute expire, so it will for sure expire in 1 hour. So I guess that is a possibility as well. You should write some code checking to see if the object exists in the cache before you try to use it. If it isn't there you will need to add it again.
If you didn't mean to force an expire of the dataset in 1hour then you should use the sliding expiriation. Then it will only expire if it hasn't be used for a certain period of time.
Hope that helps.

the problem is not appearing while i run the application in the local network !
i face the problem when i run the form throug VPN or remote connection which is slower .
i am not loosing the data after a long time i am loosing it immediately after a postback which
takes less than 2 seconeds and this happening sometimes from the first postback sometimes after 10 postbacks.
for now what i did is checking if the Dataset in the cache is still exists or not if not i am generating it again which means loosing the not saved changes .
but i want if there is an IIS configurations that could affect the cache ?
many thanks.

IIS controls a couple of things. In the app pool there is a recycle app pool that would re-set your entire web application, this includes the cache. By default this re-set happens like every 27 hours or something weird like that. Normally, I change it to recycle real early in the morning like 3am. The web site it self has many timeout settings for the session. I don't see any reason why a session expiring would affect the cache. I guess the question is how much data are you putting into web server memory when the post back occurs. If you are putting huge amounts of data into you web server memory then the cache could be cleared early because the server is running out of memory.
Hope that helps.

hmm, you want a menu? Look for some easy javascript 
This is an simple example, its not working super but i hope i can make my point with this!
<code>
<html>
<head>
<style type="text/css">
#MenuItem{
width:150px;
border-style:solid;
height:25;
}
#subMenuItem{
width:150px;
visibility:hidden;
border-style:solid;
}
</style>
<script type="text/javascript">
function openMenu(objID)
{
document.getElementById(objID).style.visibility = 'visible';
}
function closeMenu(objID)
{
document.getElementById(objID).style.visibility = 'hidden';
}
</script>
</head>
<body>
<div id="MenuItem" onMouseOver="openMenu('SubMenuItem')">My Links</div>
<div id="SubMenuItem" onMouseOut="closeMenu('SubMenuItem')">
<lu>
<li>Link item</li>
<li>Link item</li>
<li>Link item</li>
<li>Link item</li>
</lu>
</div>
</body>
</html>

Hi Mohan,
Check for the below code.
Datagrid.Databind
'After binding the datagrid
Dim item As DataGridItem
Dim i as integer=0
For Each item In Datagrid.Items
i+=1
item.Cells(0).Text=i 'Where item.Cells(0) is the first column in your datagrid if you have kept for serial number.
Next
'---------------------------------------
Or you can append the value of "i" while you are using datatable when you fill it with datareader.
Regards,
Raghu.

Please tell me the difference of...OLEDB vs SQLClient..which one is better and why?
Sujit
|
|
|
|
|
these both are providers for different types of database access.
SQLClient is a provider specially optimized to work with MS SQL server, and is very well recommended to use with sql server.
on the other habd OleDB is used with MS ACCESS.
The choice is entirely yours, as to which database you want to use. accordingly u will have to chose the provider
