Tv.Children.Add(new TreeViewModel("Child5")) Tv.Children.Add(new TreeViewModel("Child3")) TreeViewModel tvChild4 = new TreeViewModel("Child4") TreeViewModel tv = new TreeViewModel(topLevelName) For this example, however, I will simply hard code the creation of the treeview hierarchy. Setting or building your tree hierarchy is done by creating you root instance, then adding children, while you are adding your children, if they have any children, add them and if they have any children add them, etc… A recursive method works here, use one. It’s more object oriented…component oriented. I suppose another option would be to use the checked or unchecked events on the control, but I like this approach better. I mean, each time we change the value of a checkbox, we may want to change something else. If you think about it, it fits well with a checkbox.

This example will create a treeview like this. Now there is one and if you find it, I hope it is what you are looking for. I wasn’t able to find 1 post that provided all the details and source code to do what I needed. I searched the internet and pulled everything I could into a this single resource. On one of my projects I had to provide treeview selection functionality.
