Problem with SynchronizeSelection

[jamin]

Hi,

I just checked this property again but it doesn't seem to work (see my video demo).

flv.CheckBoxSelectionMode = SynchronizeSelection;

flv.Selectionmode = MultiSimple;

Please check the latest version!

Thank you!

Hi,

I had trouble posting a new question.

I’m currently experiencing an infinite loop when calling workbook.Open(stream) - Xlsio

While debugging, I found that the issue comes from a while loop in the following method that does not advance the reader:

internal void ParsePersons(XmlReader reader, WorkbookImpl workbook)

Could you please check this issue on version 32.1462?

Sample: File

Thank you.

Hi Yen,

We have included the fix to resolve the issue "Application hangs while opening an Excel document if the person tag has x18tc namespace" in our weekly NuGet release version 32.1.25. Kindly upgrade your Syncfusion packages to this new 32.1.25 version and let us know if the issue is resolved.

 

NuGet Package: NuGet Gallery | Syncfusion.XlsIO.Net.Core 32.1.25

 

Root cause for this issue:

While opening a excel document containing comments, the application hangs due to improper handling of the person list tag name and person tag name if the person tag has the x18tc namespace. This unhandled scenario causes the parser to fail, resulting in the application becoming unresponsive.

Regards,

Santip Raja.
