Link button in repeater header

P: n/a
I put linkbutton in a repeater header. I attached event handler in makeup as
onclick="btnSort_Click".
Made btnSort_Click method public. It doesn't fire if I click on it. I tried
to attach it in ItemDataBound event but I think it is too late.

What am I doing wrong?
Thanks
Shimon.

Hi Shimon,

Welcome to ASPNET newsgroup.
As for the event handler of the repeater nested linkbutton not work
problem, I'm thinking whether its a page specific problem. Generally, for
such sub control, we can register event handler for them through :

1. inline attribute in aspx page as you mentioned

2. programmatically register event handler in the repeater's ItemCreated
event.

To make it clear, I've made a simple test page which demonstrate both the
two means, you can have a test on your side to see whether there're any
difference between your problem page. Here is the code, hope helps:

Yes, you I right.
The problem was that I disabled view state for the repeater so the control
was never created after post back.
Thank you,
Shimon.
