I have a RadGrid that implements usercontrols as model popups for adding and editing items within the grid. When the user presses the submit button on the usercontrol, the Update command is sent back to the grid. The update is processed and if an error occurs, I cancel the update and show a RadNotification as a modal popup. The RadNotification shows and I create a div with a background to make it modal. So, the RadNotification is modal over the usercontrol which is modal over the grid.
This all works as expected in FireFox 19. When I try it in IE8, the RadNotification is placed underneath the modal div and the usercontrol modal. Also, the RadNotificaiton is always located at the bottom left of the screen below the rest of the page.
Why does this not work on IE8?
