We use Syncfusion GridTreeControl 10.2. We leverage the grouping by marking the child and implementing the request tree items handler.
Every time we change the underlying collection, we dont want to refresh the grid such that we lose the collapse/expand state of all nodes. We want to refresh the grid with new data but retain its current state as it is - some nodes expanded, some nodes collapsed.
I call this after the binding refreshes
dataGrid.InternalGrid.PopulateGridNodes(true);
but only after I do mouseover the grid reflects the right parent/child with + sign.
How to achieve our use case ? Is there different method to call after underlynig data changes -without disturbing the expand/collapse state.
