Hi everyone

For the check boxes for the in the windows form application, I wonder if there is a 3rd state I could use. For example, if the parent is checked then all of it's childs are checked. if the parent is unchecked then all of it's child are unchecked. But if some of the childs are checked, and the others aren't, I want to have the parent be in a 3rd state. Stating that some of it's children are checked.

Thanks for the time and apperciation.

It's not that simple. The standard TreeView control in the ToolBox doesn't support doing this natively, so you have to make your own, or find a third party control that does this for you.

There's a couple of CP articles that cover doing something like this here[^] and here[^].
