I must mention that I gathered this solution from many websites on the internet, however, I can no longer recollect exactly which ones I got which piece from. Clicking on the TreeView contol checkbox will call the SetIsChecked method because we bound it to the IsChecked property of the TreeVIewModel class in the Window.Resources tag within the XAML. The above 2 components are where the magic happens. The TreeViewModel.IsChecked is defined to call the SetIsChecked method when the state is modified. However, the most interesting part it is within the Window.Resources tag.īasically, here we bind the IsChecked property of the checkbox control to the IsChecked property of the TreeViewModel class. You can view the specifics in the downloadable source. We also need to bind the class to the presentation layer, I.e.

If the treeview item was selected its’ IsChecked value will be true. Traverse through the root object using a recursive method and perform what you requirements dictate. TreeViewModel root = (TreeViewModel)TreeViewControl.Items First, create your treeview and initialize it with the contents. Getting the selected treeview items is best done using a similar but not identical recursive method. (new TreeViewModel('GrandChild4-1')) Īs mentioned, I created my toplevel node, added some children and then added a grandchild to child4. Tv.Children.Add(new TreeViewModel('Child5')) Tv.Children.Add(new TreeViewModel('Child3')) TreeViewModel tvChild4 = new TreeViewModel('Child4')

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. I won’t describe what it does in detail here, but simply when implemented and bound to a control, it will trigger an event when the control is changed. The INotifyPropert圜hanged interface is part of the System.ComponentModel namespace. Bindin the TreeViewModel to the Window using XAML.The Get and Set Methods within the TreeViewModel.The TreeViewModel which implements the INotifyPropert圜hanged interface.There are 3 parts to focus on to create a Treeview with checkboxes. 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.
