I tried your issue with a 30000 row DataTable and could not reproduce your issue, could you provide more info on the type of data, maybe post a stack trace of the issue?
If you have a compact sample, you could submit it to Developer Support and let them debug it as well.
Simply copy/pasting the stack trace may provide additional clues. Other than that, you can try ViewState management and switch viewstate persistance to one of four possible locations:
As demonstrated in the following forum threads:
http://www.codeproject.com/KB/cs/C__ViewState_Management.aspx
http://www.eggheadcafe.com/articles/20040613.asp
This may alleviate the problem or provide additional clues.
Currently i m working as developer. i am new to infragisitcs Ultraweb grid tool.
facing some techinical issue in ultraweb grid. i have 100,000 records in the database. if i load the all the records from the server. it cause time out error. i planning to show only 20 records record per pages but the paging should be 100,000. for ex 100,000/20 = 5000. i want to get the records when i select the paging controls in ultraweb grid.
Is there any possiable to customize the ultrawebgrid control as per my request.

This calles a simple select * from and binds it.
Thanks.
I does not seem right, I've seen the grid work with thousands and even millions of records (with the correct datasource management) and even in this case - the end result would be slowness rather than exception.
The best way to proceed in this situation I believe is to send a small subset of your project reproducing the issue to our Developer Support folks - they can be reached via this link
http://ko.infragistics.com/gethelp/default.asp
If we have a repro, it will be easier to figure out what is going on.
It seems to error around 3100 records for me. Anything below, is ok. Am I missing a setting or something?
Well I shrunk my dataset size and the issue seemed to go away. But why is there a limit? And why is the paging size not helping?
