[Question] How can I select multiple `TreeView` entries?

I am trying to implement a tree view with something similar to the approach Windows takes in explorer where every entry has a checkbox. It seems like by default that functionality is not yet available - is there a workaround that I can use to enable the tree view to use checkboxes?

This is related to the MultiSelect property, but with a different UI presentation.

Closing this question as I believe it was sufficiently answered.

Its doable, theres also lots of customizations I can think of e.g.

* If you click a checkbox for a branch should it tick all leaf items

Yes, if the branch isn’t selected or only some leaf items are selected (solid state on the branch), clicking a checkbox it will mark all leaf items. On the other hand, if the branch is already selected clicking a checkbox will unmark all the leaf items.

* Ticking a branch should tick unrevealed items the whole way down the tree even though `TreeView<T>` does 'just in time' branch discovery.  So methods like 'GetAllCheckedObjects' would just return the exposed ones.

I agree, Should tick or unpick unrevealed items the whole way down the tree, dependent of the current state. Method only have to return the exposed ones (expanded).

Its pretty tough but doable.

I know, thanks for your attention. To be more tough, only display the checkbox if a property like ShowCheckbox or similar is enable. If MultiSelect and ShowCheckbox properties are enabled it acts like the above. If MultiSelect is enabled and ShowCheckbox is disabled, then the selected items will be displayed by the selected or u-selected color. If MultiSelect is disabled and ShowCheckbox is enabled clicking a branch checkbox will not tick all leaf items, but only the branch itself. If another item is clicked then the previous item must be deselected. If MultiSelect and ShowCheckbox properties are disabled it acts like currently does. If all of this doesn’t make any sense for you, then forget it 😃
