I have tried that also. The problem is javascript function do not get invoked since the page is ajax enabled. I am not able to find a way to make javascript work or any other workaround to close the child window. Thanks, Subulakshmi

Hi, That doesn't work since it is an ajax enabled page. I have tried that option. I even tried to call a javascript function in parent window using which I could close the child window but that also did not work. Tried to raise button click event in parent window but that also failed. Thanks, Subulakshmi

Hi, I have an aspx page which is having an arraylist of audio file paths. A child window is opened in which the audio is played one by one. I have a timer control to identify when an audio file completes in the child window. Once the audio file completes, I have to close the child window and return to the parent. In the timer tick event, I have to close the child window. Please tell me how I can do this. Thanks in advance Subulakshmi

Thanks. I did not know about it until now Subulakshmi
