Auto posting on a textbox with the text changed is asking for trouble,
as every single character typed fires the event. It could be that
firefox is not catching the character hit the same way and allowing you
to finish, but I am guessing that IE7 is firing the event multiple times
as the person types in characters. Unless this box only accepts one
character, I would use a button or something similar to handle the
changes you require.

I have a form with one ASP.net listbox control and three ASP.net button controls. The former is set to AutoPostBack (i.e. when user selects an item), and the three button are also submit buttons.

This works perfectly in Firefox, and Page.IsPostBack is true in the Page_Load routine.

But in IE8 and Chrome Page.IsPostBack is false whenever any of the 4 is used to submit the form.

I've checked the generated Javascript in all 3 browsers, and it's identical.

What gives ? I'm completely stumped by this :-(

(Running ASP.net 3.5 sp1 on Win2003 x64)

Cheers.
