Thank you for contacting us.
After we investigated this on our side, we can confirm that there is an issue with the LabelDefinition
property of CartesianGridLineAnnotation
when you try to set it in style. We have logged it in our feedback portal
where you can track its progress. We have updated your Telerik points, for bringing this issue to our attention.
In addition, we have modified the project provided in your last reply to demonstrate how to workaround the issue with an approach using an attached property.
Please, give this approach a try and let us know if it works.
