Hi Nicolas, 

 

Thanks for contacting Syncfusion support. 

 

We can move the scrollbar to annotation location using GoToBookmark method. Please refer to the below sample and code snippet,

Code Snippet: 

 

<button @onclick="navigate">Navigation</button> 

 

private async void navigate() 

    { 

        var annotationCollection = await PDFViewer.GetAnnotations(); 

        var pageNumber = annotationCollection[0].PageNumber; 

        var Y = annotationCollection[0].Bound.Top; 

        PDFViewer.GoToBookmark(pageNumber, Y); 

    }

Hi Vasugi,

Thank you for the fix, it's works for get the bound Y coordinate ("var Y = annotationCollection[0].Bound.Top;"), but not works has expected  for the "await Viewer.GoToBookmark(pageNumber, Y);" method because with :

pageNumber = 0

Y = 48,609375

I go to the second page of my pdf ???

Print screen of my code in sample I send you

You can reproduce with the sample I send you before.

1) When you launch my sample clic on this menu : Viewer8 Bug bound

2) And clic on field on the left menu to load annotation => the first

3) Click on TEST button

4) you see the pdf viewer got to second page

Thanks

Nicolas
