[Solved] Text not showing on Treeview

[Andrew]

I am adding nodes to a Treeview in the code behind like so:

private void CreateTreeviewNodes(Applications apps)
        {
            RadTreeListViewItem rootItem;
            RadTreeListViewItem queriesItem;
            RadTreeListViewItem queriesWorklistItem;
            RadTreeListViewItem queriesNewQueryItem;

            rootItem = new RadTreeListViewItem();
            rootItem.Header = "My Dashboard";
            rootItem.Foreground = new SolidColorBrush(Colors.Black);
            rootItem.Selected += new EventHandler<RadRoutedEventArgs>(searchTreeView_RootItemSelected);

            searchTreeView.Items.Add(rootItem);

            for (int i = 0; i < apps.Count; i++)
            {
                rootItem = new RadTreeListViewItem();
                rootItem.Header = apps[i].Name;
                rootItem.Foreground = new SolidColorBrush(Colors.Black);
                rootItem.Selected += new EventHandler<RadRoutedEventArgs>(searchTreeView_RootItemSelected);

                searchTreeView.Items.Add(rootItem);

                queriesItem = new RadTreeListViewItem();
                queriesItem.Header = "Queries";
                rootItem.Foreground = new SolidColorBrush(Colors.Black);
                queriesItem.Selected += new EventHandler<RadRoutedEventArgs>(searchTreeView_QueriesItemSelected);

                rootItem.Items.Add(queriesItem);

                queriesWorklistItem = new RadTreeListViewItem();
                queriesWorklistItem.Header = "Worklist";
                rootItem.Foreground = new SolidColorBrush(Colors.Black);
                queriesItem.Selected += new EventHandler<RadRoutedEventArgs>(searchTreeView_QueriesWorklistItemSelected);

                queriesItem.Items.Add(queriesWorklistItem);

                queriesNewQueryItem = new RadTreeListViewItem();
                queriesNewQueryItem.Header = "New Query";
                rootItem.Foreground = new SolidColorBrush(Colors.Black);
                queriesNewQueryItem.Selected += new EventHandler<RadRoutedEventArgs>(searchTreeView_QueriesNewQueryItemSelected);

                queriesItem.Items.Add(queriesNewQueryItem);
            }
        }

When I execute my code, however, the text on the RadTreeViewItems does not display until I select an item. If I then select another node its text displays but the text of the previously selected item disappears. Attached is a screenshot of the issue.

Can anyone tell me what is causing this or what I am doing wrong?

Thanks.

Hi Andrew,

I see you are adding RadTreeLISTViewItem to the RadTreeView? Try adding RadTreeViewItems.

And of course that fixes it. An obvious mistake and oversight on my part. Now I feel extremely silly. Thanks for the help, however. Who knows how long I'd have spent on this if someone had pointed on this simple error?
