Getting data from javascript

[Dave]

Is it possible to grab data from a javascript prompt window that is called from within a webform page with C# as the behind code? I know how to activate the prompt window by calling a routine from an html button in my webform. But I want to be able to send the reply back to the server. In other words, is it possible to create a popup or prompt window that can send data to the server

You can use JavaScript to populate a hidden form field in the page with data
that will then be available on the server with the next PostBack.

Hi,
you might be able to do something like this

if(window.confirm('are you sure you want to do this?')){
document.images['img'].src='Page.aspx?answer=yes';}
else{
document.images['img'].src='Page.aspx?answer=no';}

<img src="shim.gif" width=1 height=1 name="img">

Basically you're sending back either yes or no in the querystring to
Page.aspx without needing a server roundtrip.
