I am new to sharepoint provider hosted app.
1) Since postback of app happens inside iframe, users are not able to identify if they have clicked the button or not. Is there a way to show loading image on browser?
2) we have popups inside the app, which is displayed in the middle of app page, not the sharepoint page. Is there anyway to display it at the centre of the screen, so that users don't want to scroll the page to findout the popup?
