Hi Kevin,
Thanks for your interest in Syncfusion Components.
Query#:- we use the TreeGrid to display hierarchial data fetched from a remote server.
From your query we suspect that you need to bind
Hierarchal data for
Remote databinding. We doesn’t have remote data support for Hierarchical data. For remote data binding, we need to use
Self-Referential type of
DataBinding(FlatData) to TreeGrid(
which only supports remoteData). To bind self-reference data
idMapping and
parentIdMapping property is necessary to form a parent-child hierarchy.
Refer to the documentation link:-
While binding remote data to Tree Grid component, by default Tree Grid renders parent rows in collapsed state. If you want to render parentrows in Expanded state, we suggest you to use loadChildOnDemand property.
Refer to the documentation Link:-
Query#:- Is there a way to keep expanded rows open, and only refresh rows where the drag and drop occured?
If you want to maintain the Expanded/Collapsed state on drag and drop operation, we suggest you to refer below kB link:-
If your requirement is different from above, please get back to us with further details.
Regards,
Farveen sulthana T
