I posted this on the asp.net group, also. I wasn't sure whether this was an
asp.net problem or a javascript problem.
I have a page that was originally created from a program I found on the net
that works well as an html page.
It brings up a modal popup window that I have been trying to work out for
days now and this was the closest I have been able to come.
I added a little asp.net code and an asp.net button and cannot get it to
work with that button. It seems to break the javascript code.
The page works fine with or without the asp.net code (as long as the asp.net
button is not pushed).
This works fine (as before) until I press the asp.net button. I am opening
alert boxes in various locations that all fire until the asp.net button is
pushed. From that time, all links and buttons will bring up the alert box
in the first javascript funtion, but the ModalDialogShow never gets called
or it just ignores it and therefore the popup window never gets called.
Why would the asp.net button cause the Javascript to quit functioning?
Why does the popup window not close when the buttons or links are pressed on
them?
