Close child window when parent closes in asp.net

[Samy]

Hi There,
I have a child window opened from aspx page using window.open. On the
child window, I have a button(New category) which opens a grandchild. I
also have a cancel button on the child window which when clicked should
close the child and the granchild windows. Can anybody suggest me how
this can be accomplished.

I am using image buttons to do this.
This is how I am implementing, but for some reason the 'win' is
undefined.

----in the aspx page
<script language="javascript">

var win
function openwin()
{
win =
window.open('NewCategory.aspx','NewCategory','widt h=320px,height=125px,left=250px,top=500px')
win.focus()
}
function closewin()
{
if (win && win.open)
win.close()
self.close()
}
</script>
---

---in the .cs
this.New_ImgBtn.Attributes["onclick"] = "openwin();";
this.Cancel_ImgBtn.Attributes["onclick"] = "closewin();";

I cannot call the closewin() in body as onunload = "closewin()" coz
this event fires as soon as the new window opens and closes it right
away...

Can somebody get back to me as soon as possible? Thanks a lot.

Samy,

I'm doing this, and it works just fine. Are you declaring the script
block in the head of the HTML document, or in the HTML document itself? I
did it when it was in the head of the document, but it could be different if
you declared it in the middle of the actual HTML.

Hope this helps.
