Page Hangs

P: n/a
Hi -

I have an ASP.NET page that hangs (some times; if it loads for you, try
refresh/F5 several times) when I try to run it on my localhost. It contains
an HTML table for formatting, and within the table are several labels,
textboxes, and validators. One of the textboxes is multiline and readonly,
and the codebehind page has code to read a text file into it. (The text
file is about 21,000 characters with spaces.) The aspx page has a
javascript function to set focus on the first textbox when the page loads.
I've also included "<pages smartNavigation="true"/>" in web.config.

My Page_Load event and the entire aspx page is below. When the page hangs,
pressing Esc will stop the hang and display the form, but the text in the
multiline textbox is not complete (last line should be "-- End Of File --").

If I remove the table row with the multiline textbox and leave the rest of
the table rows as they are, the page doesn't hang. If I remove all of the
table rows except the one with the multiline textbox, the page doesn't hang
and the text file loads to end of file.

Can anyone see what might be causing the hang??

Thanks for your help.

- Jeff
