Main window loading spinner issue

Question

Hi all, I'm facing one issue in wpf, I need to show show/hide the loading spinner in main window but at the same time other user control is open on main window so I'm unable to show/hide loading spinner. Can anyone help on this. Thanks in advance

make sure you that code of setting true on main windows is inside main thread. check thread details during debug time .e.g execute that task System.Windows.Threading.Dispatcher.Invoke(action);

Hi Ashutosh, I'm already doing which you suggested, it's working in user control not in main window because I'm loading user control in main window

Hi Laxmidhar, I tried your solution but it's not working because already we are rendering another user control on top of main window so is it possible to show spinner of main window if yes can you guid me

have one bool property like IsBusy on your viewmodel binded with spin control and when spin is open make this property to true and makes ure you have data troggiger where other control visibility is set based on this flag.

Hi Laxmidhar, Thank you for your response and this is not my problem I'm facing different issue. I will explain you clearly I'm using MVVM architecture in wpf so all the user controls will load on main window and I'm capturing scanning event in main window but I need to show loading spinner icon on login page user control so can you provide any other solution
