#FLOOLA CRASHES ON DRAG AND DROP CODE#
Use a debugger to locate the reentrant code and, if necessary, move that code to an asynchronous event handler. Unhandled exception at 0x00007FF9631FBD5C (KernelBase.dll) in App5.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x00000267752A9ED0, 0x0000000000000003).Įxception thrown at 0x00007FF96311D759 (KernelBase.dll) in App5.exe: WinRT originate error - 0x80004005 : 'Reentrancy was detected in this XAML application. I am unsure if this crash is related to the DataGrid, or is more generally relalted to Project Reuinion The code that triggers the crash is being dispatched asynchronously, and is locked with an AsyncLock. (Uncommenting the return at line 62 of seems to avoid the crash). The eventual crash seems related to manipulation of the Margin property of the DataGridRow. Note: Adding more UI panels in the XAML to nest the DataGrid deeper in the hierarchy causes the issue to manifest faster and generates more errors in the debug window. Eventually the debugger will break due to Reentrant code exception.Observe the MANY error generated in the debug window.drag an item in the datagrid and move it around the datagrid and the desktop (in and out of the app window).When performing a Drag and Drop operation on a DataGridRow, an error is thrown at random times.
