Treeview find the same state

[Chris]

Hello,

With treeview is it possible to find the same unfolded opening state of items when arriving on the tree?
Like a cache of the state.
Thank you

Hello Chris, 

Greetings from Syncfusion support. 

Yes, we can persist the state of the TreeView using enablePersistance property. This property enables or disables persisting TreeView state between page reloads. If enabled, following APIs will persist. 

1. selectedNodes - Represents the nodes that are selected in the TreeView component.
2. checkedNodes - Represents the nodes that are checked in the TreeView component.
3. expandedNodes - Represents the nodes that are expanded in the TreeView component.

The default value of the property is false. Here is the API link for your reference.

Please get back to us if you require any further assistance. 

Thanks,
Christo
