Page not found when doing postback

[hphan1229]

I have an ASP.net application running on framework 1.1. The page has a datagrid that is populated based on user's selection. There's a link button on each row to open up another window to display the detail for a specific row. The page is working fine when the number of rows on the datagrid are around couple thousand. When the number of rows reach over 10k, clicking on the link button to cause the postback will result a page not found error.

I've put a breakpoint on the Page_Load event handler to see if it is called but it's not. Have anyone run into this problem?

Just in case anyone runs into the same problem. I found out that the httpRuntime parameter in the machine.config has the maxRequestLength set to 4096K. I've increased this to 8192K and that fixed the problem.
