In WatiN how to wait until postback is complete

Question

in WatiN how can I wait until postback is complete.

For example:

// Postback response modifies update panel elsewhere on page
browser.Text("id").TypeText("asd"); 

// WatiN doesn't wait until postback is completed (what code should I replace it with?).
browser.WaitUntilComplete();

Answer 1

You could check if IE is busy rather than complete.

while (((SHDocVw.InternetExplorerClass)(_ie.InternetExplorer)).Busy)
        {
            System.Threading.Thread.Sleep(2000);
        }
