Hello
I have a radtreeview control in my application and a functionality to expand some nodes with a click of the button. Now it expands more than 3000 nodes and the performance is not so good as it tries to redraw the tree as it goes. The treeview is bound to ObservableCollection. What would be the best solution for performance here? Should i change binding to List and notify property changed in the end of my procedure or is there something better you could recommend?

Hi Ignas,
The RadTreeView control is designed to visualize large amount of hierarchical data and it exposes mechanisms which can boost the performance of the control if needed. One of these mechanisms is the UI virtualization.
By using this mechanism you will force the control to create the UI containers only for the items that can be visualized in the current viewport of the control. You can find more information about this feature here.
Please try the UI virtualization out and let us know your feedback.
