Hi Brijesh,
SfTreeGrid doesn’t have support for filtering in UI. But you can do the filtering programmatically in SfTreeGrid. Please refer the below User Guide documentation for more details about programmatic filtering in SfTreeGrid.
We already have a dashboard sample for the programmatic filtering in SfTreeGrid from the below installed location
Path Location: \{installed location}\Users \{Users.Login}\AppData\Local\Syncfusion\EssentialStudio\{installed Syncfusion ES build version}\WPF\SfGrid.WPF\Samples\TreeGrid\FilteringDemo
Also refer the same from the below attachment to perform filtering in SfTreeGrid control.
Please let us know if you need further assistance on this, we will happy to assist you.
Regards,
Gnanasownthari T.
