Progress Barr by loading GRID

Hello,
I have “Search” Application which starts with help of sc_redirect different GRID applications. Some Grids loading relative long ( SQL Request needs 20-40 Seconds)
Would be it possible to make some kind of animation with progress bar ? All advices which was found are only for forms of grid for “onHeader” event.

With best regards,
Stanislav

i did this once by using a gif as a background. the gif was a loading bulb. when the grid is loaded the background is behind the grid
