is there a listener for a busy dockpane?

nadja

Currently I add whenever possible the following two functions at the start resp. end of a function. This approach is cumbersome and doesnt always work, because sometimes I get a wrong thread error regardless if it is an async method or not... 

 public void ShowBusyIndicator()
 {
     BusyIndicator.Visibility = Visibility.Visible;
 }

 public void HideBusyIndicator()
 {
     BusyIndicator.Visibility = Visibility.Collapsed;
 }

thus i was wondering, if it wasn't possible to listen somehow if the addin is currently busy. I found https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic10430.html this property. now I'm wondering, if it can be used to listen to it and to show or collapse my busyindicator. any help would be appriciated.

Hi,

IsBusy is a property you can override. Without overriding it always returns false. So first step you need to override it :

 

        private bool _isMyDockpaneBusy = false;
        public override bool IsBusy
        {
            get
            {
                return _isMyDockpaneBusy;
            }
        }

 

Then in your dockpane calculation method you must update _isMyDockpaneBusy depending on your calculation status:

 

private void DoMyJob()
{
    _isMyDockpaneBusy = true;
    NotifyPropertyChanged("IsBusy");
    try
    {

    }
    catch (Exception)
    {

    }
    finally {
        _isMyDockpaneBusy = false;
        NotifyPropertyChanged("IsBusy");
    }

}

 

Last step would be to bind in xaml your BusyIndicator Visibility to dockpane property IsBusy. For that you need to use Converter which converts bool value to visibility enum. You can make a search on web with string "wpf bool to visibility converter invert" and you will find different implementations of converter.
