How can I manage checkboxes in .Net Forms.TreeView?

Question

I have a .NET desktop application with TreeView as one of the interface elements.

I want to be able to repeatedly select this TreeView, only one that is not supported at all.

So, I am adding flags to the tree. My problem is that only some elements are available, and those that cannot, cannot cascade sequentially.

Is there a way to disable or hide some checkboxes while others are displayed?

Answer 1

The default behavior of a TreeView is that if the Checkboxes property is set to true, these flags will be shown for all TreeNodes.

Answer 2

, . TreeNode BackColor, node. SelectionChanged, Shift/Control, , node / . Generic::List<> , .

Answer 3

MultiSelectTreeView :

Why doesn't .NET have a multi-element tree? There are so many uses for one, and including flags in a tree structure is a pretty disgusting alternative.
