TreeView does not check children nodes when checking the parent node #996
Description
Truong Nguyen asked 2017-08-07 07:12:30 UTC
Is this a missing feature for TreeViewControl?
I try check the parent node, but its children nodes are not checked.
I found out that I can implement it with AfterCheckEvent, but is it necessary for me or any developers?

That's by design. Automatically checking all child nodes and children of children would potentially break a lot of code since it's not a standard behavior in winforms or in most treeview controls we looked at. It also would require the opposite functionality - detect when all children are checked and automatically check the parent.
You can find a lot of references about this related to asp.net, winforms, telerik, and many other component libraries.
It can probably be added as an option.
Best,
Luca
