Hi. I have an important app that loads as the default app in my main menu. Unfortunately, the server can often take a few seconds if it is busy, so my users only see a menu with a blank frame under it, till the app loads (it is a grid with graphic images in certain fields).
Anyway, my question is, how can I display a modal window or centered div that says “loading…” OR use an animated GIF that shows something is happening, before the app loads the grid records on the screen. After it loads, I want the message to be invisible.
Thanks for any ideas
