I have a page with a user control which gets some data updated via a modal popup. Upon clicking "ok" on the modal popup - the new data is being written to the database - but the base page doesnt "reload" to show the updated data. How do I get that to happen?
1) Don't set the OKControlID property on the ModalPopupExtender.
2) In your Page_Load, set OkButton.OnClientClick = string.Format("$find('{0}').hide();", modalPopupExtender1.ClientID);
Explanation: Setting the OkControlID stops the button from posting back. Instead, manually use javascript to hide the extender, which will allow the button to post the form.
