so i have a user control that i load dynamically at run time into an asp:panel.
i use AJAX popup extender to make this panel a modal window showing the dynamically loaded user control.

the problem is the control fires events the first time and then when buttons on the UC are clicked like SAVE, DELETE, CANCEL there is no post back and the button click events dont execute.

how can I get the button events to work as expected on post backs?

Well, it's hard to say without seeing any code, but I suggest that you dynamically load you UC on page_init if you are not doing so (especially on postback)

Hi,

(1) Have you bind these all controls of your UC with some event handler?

(2) Is the AutoPostBack property of Controls is set to True.

Hi there,

ASP.NET has a big gotcha with dynamically created controls. Did you know that with dynamically created controls, you need to re-create and re-add the controls to the page on EVERY page load? Not only that, you will find that with dynamically created controls their ViewState and their event will go missing or will not fire IF they aren't recreated on the page_init event.

If you are using dynamically created controls then you'll be wise to make sure you recreate them on every page_init.
