Could you help me to build the treelistview to show the data which screenshot is attached!

Hi Jerry,

Please find attached a sample project. Hope it will get you started.

The sample works on my machine, but I want to clear and repopulate each element in the treeview. I tried rebinding, but that doesn't clear the old data.

How would I modify this sample if I want to update the treeview as a result of clicking a button?  In other words, add the contents of MyViewModel.AllData only when the button is clicked?

I seem to get exceptions when the tree is loaded and no rows have been added.

Hi Chris,

I have tested the case by defining a single button and handling its Click event as follows:

private void RadButton_Click(object sender, RoutedEventArgs e)
        {
            this.tlv.ItemsSource = (this.Resources["MyViewModel"] as MyViewModel).RootItems;
        }

However, it works correctly on my side. I am attaching the updated sample. Is your scenario the same or am I missing something ?
