VintaSoft PDF .NET Plug-in Discussions

Hi,
I implemented annotation copy paste and I am seeing a Argument out of range exception on the paste operation.
I have tried the implementation two ways.
First I implemented the copy paste functionality similar to your PdfEditorDemo application.
I then implemented the functionality from the annotaion tool CopyAction and PasteAction properties.

Where the _pdfAnnotationTool is PdfAnnotationTool.
The GetUIAction as well as the TryGetCurrentToolActions methods in the GetUIAction method are copied out of the demo app

         // In context menu for copy.
	 CopyItemUIAction copyUIAction = GetUIAction<CopyItemUIAction>(GetAnnotationTool(_pdfAnnotationTool).ImageViewer.VisualTool);
         if (copyUIAction != null)
         {
             copyUIAction.Execute();
         }

         // In context menu for paste.
	 PasteItemUIAction pasteUIAction = GetUIAction<PasteItemUIAction>(GetAnnotationTool(_pdfAnnotationTool).ImageViewer.VisualTool);
         if (pasteUIAction != null)
         {
         	pasteUIAction.Execute();
         }

I also implmented the annotation tool UIActions

        // In context menu for copy.
        CopyItemUIAction copyUIAction = pdfAnnotationTool.CopyAction;
        if (copyUIAction != null)
        {
              copyUIAction.Execute();
        }
                
         // In context menu for paste.
        PasteItemUIAction pasteUIAction = pdfAnnotationTool.PasteAction;
        if (pasteUIAction != null)
        {
             pasteUIAction.Execute();
        }

Here is a stack trace of the error. This happens on the pasteUIAction.Execute:

I am not sure what is going on here. It looks like the There in some problem inserting the pasted item into the annotation list.
Is there some other functionality that I am missing for implementing the copy paste operations?
Do I need to be doing something with the clipboard?

Thanks

Hi Harlan,

Have you solved the problem? We still not received the project, which allows to reproduce the problem on our side.

Best regards, Alexander
