IsPostBack == true, even though its a callback

[Angel Of Death]

How come if I have a server side callback function, the IsPostBack value
is always true , when I check it in the Page_Load ?

Because a callback uses postback.

Because a callback uses postback

if(IsPostback)
{

if(IsCallback)
{
DoCallbackSpecificThings();
return;
}

DoPostBackStuff();
}

Does it?

I was under the impression that a callback doesn't use post back since
we're using it via some ASP.NET control that explicitly states that it
uses callbacks so that postbacks are not used (causing a page re-load).

So are they lying?

Yes and no. The data is posted back to the server, but without a page
refresh. IsPostback == true because data has been posted back to the
server, IsCallback is also true because it's a client-side call back
request.


I assume that IsPostback is set to true when the request to the page
contains form data.
