I am using JavaScript in my project.
Problem: In my project I used window.open('..');
and it open a new browser window.Inside that window I have data entry form and in Parent window I have a button called Save Record but when user click on that button at that time I have to check if the child window is not closed then I have to show a warning message to user.
How can I do this using Javascript or asp.net ?
Please give me suggestions.
Thanks.
