Stop disappearing ModalPopup panel (shown by ModalPopupExtender ) on changing text of a textbox (TextChanged event fired by AutoPostback)

Question

Hi I have a html table inside of a panel control. It will be shown by a ModalPopupExtender by clicking on a LinkButton.

inside of the panel, there is a textbox which its "AutoPostBack" property is Ture and when user enters a value in it, TextChanged event is fired but unfortunately, the panel also disapears.....

what's wrong?

Answer 1

Try placing an update panel inside the modal panel

Answer 2

Mark Blake is correct, make sure it is actually inside the model panel rather than just wrapping the modal panel, also make sure you have defined the OkControlID setting on the ModalPopupExtender
