Localization Issue for Chart Render Exception - under French localization

I'm using latest blazor version 25.1.39 in demo app

Framework like, Blazor webAssembly , We found issue while rendering Chart under French localization. We use multi level labels to support our requirement. Internally , most localization for this multi level labels chart working fine, but under fr-CA if fails rendering with this error which indicates it is internal in the Syncfusion component and it handling of numbers with cultures where comma is the decimal point. For example in fr-CA . (dot) is not a number format but the code seems to be treating it as such.

Error is:

Priyansh,

We are glad to announce that our v25.1.41
patch release is rolled out; we have added the fix for reported issue. You can use the latest Syncfusion.Blazor.Charts NuGet package.

Root cause:

When changing the culture in the chart while using multilevel labels, the grouping separator for double values is not applied properly.

Fix:

We have added the invariant culture to the grouping separator for double values when using multilevel labels.

NuGet Package: https://www.nuget.org/packages/Syncfusion.Blazor.Charts/

We thank you for your support and appreciate your patience in waiting for this release. Please get in touch with us if you would require any further assistance.

Regards,

Gopalakrishnan Veeraraghavan
