TreeViewItem used for dynamic FluentTreeView generation via Items should have Data field to be able to set FluentTreeItem.Data

[KrystofZacek]

FluentTreeItem has Data property to attach custom data to it which can be very useful. However, there is no way to attach these Data when providing the items to the FluentTreeView programatically using Items parameter. The Items parameter takes collection of TreeViewItem class objects and this class has no Data field. I propose to add the Data property to the TreeViewItem class and use it to set the Data of FluentTreeItem.

This would help with my issue #3474 where I want to apply style individually to each tree item. I have experimented with sub-classing TreeViewItem to achieve something similar but this suggestion is much better in my view.

@ianclough then vote up the issue. We are probably not going to change this if there is only one person who interests this.

[KrystofZacek]

IMO this is rather a bug or omission since there is no way how to programatically set the Data to the treeview item.

But yet, you are the first person who ever mentioned this..

That leads me to the conclusion that in general (which is something different than your specific use case!) this is not a highly sought after functionality. As you know, we have only very limited resources (as this is a side-project for the main maintainers), So if there is no broad interest in this, we will not prioritize working on this.

We are always happy to receive PRs. So if you want, it is totally possible to add this yourself and give back to the community.
