This does not happen all the time but is happening enough when attempting to cut/copy and paste cells in a spreadsheet.

Included is a video of this occuring when I was recording.

I'd obviously want to not want this occuring but would also like a way to prevent these unanticipated issues from crashing the application and losing any unsaved work.

If you PM me then I can send more of the items across for attempting to repro and obtaining a full call stack when it does occur.

I'm doing multiple cut/copy paste actions and it does not occur with regular frequency.   ie, I can do it once and it will fail and the next time it will succeed.

Call stacks that occur when it happens are:

System.InvalidOperationException: BeginTransaction without CommitTransaction
   at Syncfusion.Windows.Forms.Spreadsheet.History.HistoryManager.BeginTransaction(String s)
   at Syncfusion.Windows.Forms.Spreadsheet.SpreadsheetCopyPaste.Paste(GridRangeInfoList range, PasteOptions e)
   at Syncfusion.Windows.Forms.Spreadsheet.SpreadsheetCopyPaste.Paste(GridRangeInfoList range)
   at Syncfusion.Windows.Forms.Spreadsheet.SpreadsheetCopyPaste.Paste()
   at Syncfusion.Windows.Forms.CellGrid.SelectionController.HandleKeyDown(KeyEventArgs args)
   at Syncfusion.Windows.Forms.Spreadsheet.SpreadsheetGrid.ProcessKeyEventArgs(Message& m)
   at System.Windows.Forms.Control.ProcessKeyMessage(Message& m)
   at System.Windows.Forms.Control.WmKeyChar(Message& m)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at Syncfusion.Windows.Forms.ScrollControl.WndProc(Message& msg)
   at Syncfusion.Windows.Forms.Spreadsheet.SpreadsheetGrid.WndProc(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)


If this helps.    I will endeavor to continue to get call stacks when it does occur and confirm that it is always occurring at the same point.

Hi Spotty, 
 
Thanks for using Syncfusion product. 
 
We have tried the cut/copy paste option using below attached sample in our latest Syncfusion  product version 16.4.0.52. But the sample is working fine as we expected. Please let us know the exact use case to reproduce your reported scenario and let us know the below attached sample differ from your customization. It will be helpful us to investigate further.

As I stated the repro is not a stable repro and occurs periodically when testing my applications which is doing a lot of cut/copy/paste activities enough that it has become noticeable and was tracked when I was videoing a walkthrough of the application.    I can provide a repro project.   This is material that I would not like to be made publicly available but would like to fix the problem.

This code is the code on other cut/copy paste problems that have been encountered and your having problems reproing.    

As for the code - the cut/copy/paste actions have not user code.   These are merely taking cells in the spreadsheet and acting upon them using the default spreadsheet implementations so there is absolutely none of my code involved in the cut/copy paste functionality.    It case occured using either the context menu or Ctrl C,X and V shortcuts.

Hi Spotty,

Thank you for your patience.

You can resolve the reported issue by handling the below highlighted code in CustomRenderer.cs file on your application. Kindly try with this and let us know if this helps you. 

Protected Overrides Sub OnEditElementLostFocus(sender As Object, e As EventArgs) 
        MyBase.OnEditElementLostFocus(sender, e) 
        'To commit the cell value.  
        If Me.Grid.CurrentCell.IsModified Then 
            Me.Grid.CurrentCell.EndEdit() 
        End If 
 End Sub 

Regards,
Deivaselvan

Yes i put this in at your advice to deal with another issue which then resulted in consistent repro of same error.    I suspect that thwre are still ways to generate this error without this code in place.
