Xamarin V16.2.0.41 Crash on Delete Annotation/Text Annotation/Shape/etc.

The app crashes when trying to delete anything in the pdfviewer control

Example when delete free text

ScrollViewEx.DeleteEditAnnotation (Syncfusion.SfPdfViewer.XForms.FreeTextAnnotation annotation)

PdfViewerDependencyService.RemoveAnnotation (System.Object nativeObject, System.Object annotation)

SfPdfViewer.RemoveAnnotation (Syncfusion.SfPdfViewer.XForms.IAnnotation annotation)

EditAnnotationToolbar.Delete_Clicked (System.Object sender, System.EventArgs e)

Button.SendClicked () D:\a\1\s\Xamarin.Forms.Core\Button.cs:133

ButtonRenderer.OnButtonTouchUpInside (System.Object sender, System.EventArgs eventArgs) D:\a\1\s\Xamarin.Forms.Platform.iOS\Renderers\ButtonRenderer.cs:135

UIControlEventProxy.Activated () /Library/Frameworks/Xamarin.iOS.framework/Versions/11.10.1.178/src/Xamarin.iOS/UIKit/UIControl.cs:38

(wrapper managed-to-native) UIKit.UIApplication.UIApplicationMain(int,string[],intptr,intptr)

UIApplication.Main (System.String[] args, System.IntPtr principal, System.IntPtr delegate) /Library/Frameworks/Xamarin.iOS.framework/Versions/11.10.1.178/src/Xamarin.iOS/UIKit/UIApplication.cs:79

UIApplication.Main (System.String[] args, System.String principalClassName, System.String delegateClassName) /Library/Frameworks/Xamarin.iOS.framework/Versions/11.10.1.178/src/Xamarin.iOS/UIKit/UIApplication.cs:63

Hi Oliver,  

Sorry for the inconvenience caused.  

The mentioned issues occurred because Syncfusion NuGet packages at nuget.org do not have latest code changes. The same packages at nuget.Syncfusion.com are up to date. Kindly use the following link as the Nuget package source.  

https://nuget.syncfusion.com/nuget_xamarin/nuget/getsyncfusionpackages/xamarin 

 

We will update the packages on nuget.org and will let you know once it is done.  

Best, 

Navaneetha Kannan
