Hi Daniel,
Thanks for contacting Syncfusion support.
We regret to inform you that, currently we do not have FrozenRows support in SfTreeGrid. We have logged this requirement as a feature request in our database. We will implement this feature in any of our upcoming release. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know when this feature is implemented. We appreciate your patience until then.
Thank you for requesting this feature and helping us define it. We are always trying to make our products better and feature requests like yours are a key part of our product growth efforts.
Please let us know if you have concerns.
Regards,
Mohanram A.
