Determine why Bound Data is not available at PostBack

Question

I've got an ASP.NET GridView that's been extended to provide a "row click" functionality. I data bind anywhere from 1 to 10 records and display it to the user.

The bug I'm hitting is that the control will not have any data associated with it on postback.

I have observed this behavior only when I click on a row before the rest of the page is finished loading and can re-produce the problem, but I have no idea why it is occurring.

Any suggestions are much appreciated!

You are going to experience a lot of difficulty with ASP.NET postbacks when you trigger them before the page has a chance to finish loading. Postback events work by inserting values via javascript into hidden inputs on the page and submitting the main form. The problem is that if you trigger the postback early you cannot guarantee whether all the controls and the hidden inputs have been completely rendered.
