I got rid of it. Initially the problem cause was, click on 'ok' to message box which was generated by JavaScript 'alert'. I tried to put MessageBox from System.Windows.Forms reference. Using MessageBox ,got the solution.

But I did not understand the reason, why using 'alert' was causing problem. If someone can throw light on it, it would be helpful for me and may be for others as well.
