How to refresh or reload SfDiagram?

[Mosin]

Can you please help me with Reloading or refreshing SfDiagram in Xamarin Forms? Another problem I am facing is assigning data source after async method(Web service). As per this thread https://www.syncfusion.com/forums/137476/begin-node-render-event-not-work-in-async-method if I used wait method then it is freezing my UI that I can't do and after that also it is not working. So I have two questions which are listed below.

1. How to refresh/reload SfDiagram for Organization chart?

2. How to use a web service for Data source of SfDiagram?

For your reference, I am getting below error with async method.

Error: BindingExpression path error: 'ToolTip_Pivot' property not found on 'Syncfusion.UI.Xaml.Diagram.Controls.DiagramThumb'. BindingExpression: Path='ToolTip_Pivot' DataItem='Syncfusion.UI.Xaml.Diagram.Controls.DiagramThumb'; target element is 'Windows.UI.Xaml.Controls.Border' (Name='thumb'); target property is 'ToolTip' (type 'Object')

Stack Trace:   at Windows.UI.Xaml.DependencyObject.GetValue(DependencyProperty dp)

   at Syncfusion.SfDiagram.XForms.UWP.DiagramDependencyService.Clear(Object nativeObject)

   at Syncfusion.SfDiagram.XForms.SfDiagram.Clear()

If you can help me with the above issues then it will be great for me.

Hi Mosin,

Sorry for the inconvenience.

Yes, we do have a support for loading data to organizational chart in SfDiagram using web service, but we have some known issues while loading data source. The fix for this issue will be included in our 2020 vol 1 Service Pack 1 release.
