how to make a modal progress window

[Mark Kamoski]

Everyone--

How can one make a modal progress window?

That is, I have an ASPX page that has 3 connected DropDownLists which much
be selected in order. Select the 1st and it populates the second. Select
the 2nd and it populates the 3rd. And so on.

I have wired a JS popup to them, which says "Please wait while
processing..."-- but it is not modal. It does, however, automatically close
when the background postback is done.

Is there very easy way to do this?

(I realize that I can open a modal window via JS and pass parameters to it,
but I do not want to user to have to manually close the modal window. I
need it to say "please wait" and then dismiss itself when the parent page
is done with its postback. It seems like the child would need to know when
the parent is done, and so on, but I don't know how to do this.)

Any ideas?

(Code samples are greatly appreciated.)

Thank you.

Lose the popup. Redirect or refresh the page to display the message.

Arrange for a layer (eg. DIV) to cover the entire page area so that clicks
don't go through it to the page (you can use your popup if its DHTML) to do
this by expanding it and making the info bit centered vertically and
horizontally).
