We have a very annoying issue with the RadAjaxManager and RadAjaxLoadingPanel controls.
When two or more Ajax requests are sent, two or more RadAjaxLoadingPanels are shown and only the first one is hidded... so the other AjaxLoadingPanel stay on screeen... letting the user know that the application is crashed or blocked...
The bug can be easily reproduced with onlne Telerik samples pages.
For exemple with this page :
- Clicking a day in the calendar produce a postback with a LoadingPanel => OK
- Clicking the "Clear Selected Dates" produce a postback with a LoadingPanel => OK
- Clicking a day in the calendar then clicking the "Clear Selected Dates" before the first RadAjaxPanel is hidded make the second RadAjaxLoading panel loops infinitly => BUG
Hope this bug will be fixed soon,
