AFF 27 Jul 2015
MFA 01 Jul 2015

for that how can i do in asp.net using c#.

function windowClose() { window.location.reload(); } var foo = window.open("foo.html","windowName", "width=200,height=200,scrollbars=no"); foo.onbeforeunload= windowClose; if your popup page is using asp.net only than make use of seesion variable to pass data to your parent.
