We have noticed this strange behavior when using the onbeforeunload javascript event. If you have a bound RadGridView, using the ItemsSource property, with just a single item in the grid, the browser will hang indefinitely under IE 9 and Safari 5 when you use the onbeforeunload javascript event. WIth no items in the grid or when using Chrome everything works perfectly, Firefox 3.6.13 seems to hang but eventually returns but grinds to halt. If we comment out the RadGridView control everything works as expected. Are you aware of anything that might be causing this?
below is the script code in the Default.aspx that we are using.
window.onbeforeunload = function () {

Hello,

Can you try the regular DataGrid instead to see what will be the result? Can you post more info about RadGridView version?
