Hi,
I've a very strange problem: my textboxes are not refreshing, while
labels are. (viewstate is off as the repeater on my page can contain a
lot of data).
Situation:
Button and repeater on page.
The first time the repeater should show this (and it does):
NonPostBack1
NonPostBack2
NonPostBack3
On Postback (=clicking the button), the repeater shows this:
NonPostBack1
NonPostBack2
NonPostBack3
PostBack4
PostBack5
While it should be:
PostBack1
PostBack2
PostBack3
PostBack4
PostBack5
the code and page are below. It is very simple, to narrow the problem.
Anyone an idea ? I've been trying almost everything and I'm becoming
quite desperate..
