Problem with TextMarkupAnnotation when first time open a file

[Roxy Cole]

Hi guys!

I'm using SfPdfViewerControl in UWP with the latest version(24.2.7) of the library and have encountered some unexpected behavior. There is a bug with both text selection and any text markup annotation when the first document opens. Text selection and markup don't work at all. When I load the second file, text selection, and markup start working as expected.

I've investigated this issue and can confirm it has appeared starting from the 18.3.0.42 version of the Nuget. In the previous 18.3.0.40 version, there were no such problems.

Thank you in advance for your reply.

Thank you for the provided solution. But the problem is that I don't use the default toolbar. I'm trying to use SfPdfViewerControl.UnderlineAnnotationCommand.Execute(true) to turn on the annotation mode. I have created a very basic sample with a few lines of code to display the issue(please see the sample attached). Also providing you some screenshots

As I mentioned before, when I open the first file, annotations and text selection don't work. For all the next files open everything work as expected. The issue has appeared starting from the 18.3.0.42 version of the Nuget. In the previous 18.3.0.40 version, there were no such problems.

We were still unable to replicate the issue Kindly find the replication video on the sample provided. We suspect that this issue might be caused by a specific PDF document.

Sure. Please see the demo and file attached. 

Note: The same instance of an app which I've provided you earlier has been used(x64). Similar issue happens with any other file I've tested so far.

Thank you for your help!

Thank you for your work, guys!

We have resolved the issue “Cannot add Textmarkup annotation and copy text when PDF document loaded” and now the fix for the same is available in our latest weekly NuGet(v25.1.37).

 

The root cause of this issue is that while loading the initial page, it will not completely check whether the glyphs are present and will complete the text selection environment creation process. Now the process waits until the glyphs of specific pages are created.
