show wait cursor or rotator during tab change?

[Lee Morgan]

I have an application that I would like to add some sort of wait indicator to during changes in tab selection.  Each tab has 15+ RadSlider controls on it, and upon first navigation to each tab the browser freezes for about 5 seconds then I get a wait cursor (the browser reports as not responding) for another 5+ seconds.  I would like to show some sort of visual indication from the beginning.  I have tried showing a modal popup, showing a spinner, and changing the cursor.  Anything that involves an update of the display never shows, however alerts do show.  Is there any way to force processing to pause and update the display during the OnClientTabSelecting event?

Hi Mark Chamberlain,

You could set the style of the body element to have "cursor: wait" e.g.

document.body.style.cursor = "wait";

And unset the cursor, or set it to "auto", once everything is loaded.

You can find more information about the "cursor" style property here --
