Hi Sven,
Currently these options are not available, you can get a better understanding of this by reviewing the following documentation article => Migrating the TreeView from Xamarin.Forms to .NET MAUI - Telerik UI for .NET MAUI.
Specifically, see that the Expand() and Collapse() methods have no .NET MAUI equivalent right now. The same is also true for the ItemExpanded and ItemCollapsed events.
Note that this is the first iteration of the control and we are adding more features as time goes on. To help prioritize certain features over others, I have opened the following dedicated Feature Requests:
- TreeView: Add Expand and Collapse methods for items
- TreeView: Add ItemExpanded and ItemCollapsed events
Note: You are already subscribed to the items, and I have added your upvote, so there is no further action needed on your part.
As for an alternate approach for the events, you can consider use the ItemTapped event and read the value of the node to gather needed information => .NET MAUI TreeView Documentation - Events.

Hi Sven,
There are methods for expanding/collapsing all items, not a single item. I see that you have logged two features for this:
methods for expand/collapse item https://feedback.telerik.com/maui/1617134-treeview-add-expand-and-collapse-methods-for-items
events for this: https://feedback.telerik.com/maui/1617136-treeview-add-itemexpanded-and-itemcollapsed-events
There isn't a workaround I can suggest for this. The features must be implemented in the control.
