Problem implementing Script Callback (ASP.net 1.1)

[eguthrie]

I'm trying to implement a callback in Asp.net 1.1. When I do a simple test it works correctly, so I know I have all the pieces in place.

The problem I'm having is in the RaiseCallBackEvent method in the server code. Since there is no postback, how do I access textbox values changed on the UI? For instance, there's a textbox called 'Phone'. If I enter a new value, then click the button that triggers the callback, then try to get the changed value.

I've tried getting the values for Phone.Text, Request.QueryString"Phone"], and Request.Form["Phone"],and all return null values. In fact, I don't even get the original value. The Request.Form & Request.Querystring don't contain any values.

Also, before triggering the callback, I have a dataset stored in cache. But when I try to access the cached dataset within the RaiseCallbackEvent method, it also returns null.

Can someone please tell me how to gain access to these objects during a callback?

Thanks in advance for any help.

eguthrie: until someone drops in with an idea or two on this I did a cursory review date restricting a search at Google Groups using "RaiseCallBackEvent" and saw a handful of post dealing with what looked like a similar issue. One of these posts seemed relevant (Click here). Post a bit of code here as well and it will help someone coming by further develop the issue. Might have to do with postback details - might be able to impliment javascript, etc. Post back a bit of code showing the relevant secions and someone here will take a closer look.
