Hi Alex,
Greetings from Syncfusion support
In this recent release (Essential Studio 2023 Volume 3 Main Release v23.1.36), we have deprecated the 'TooltipTemplates' tag in the Blazor Tooltip component. Instead of that TooltipTemplates tag, you can use ContentTemplate. We have attached the sample with contentTemplate for your reference. Please refer the attached sample. Also we want to convey that, we will add the additional information related to contentTemplate in documentation and it will be reflected in any of our upcoming release.
If still issue persist, kindly share the video demo of an issue and share issue reproducible sample or reproduce a reported issue in the provided sample. It'll be helpful to validate your query and provide precise solution ASAP from our end.
Please let us know if you have any concerns.
Regards,
Sarvesh
