Hello,
I have a sorted dictionary property:

C#

public SortedDictionary<DateTime, bool> Days { get; set; }

How do I bind the key names of this dictionary to the TreeView children, preferably without the complications of MVVM?
Root item should be a string property from another object.

Hi,

you can use Itemtemplate property to do this.

XML

<treeview itemssource="{Binding Days}">            
            <treeview.itemtemplate>
                <datatemplate>
                    <textblock text="{Binding Key}" />
                </datatemplate>
            </treeview.itemtemplate>
        </treeview>

if you have different types of objects in treeviewItems you can use template selector for treeview item template (in case you have to bind other types than sorted dictionary).

Use the following code for xaml,

XML

<TreeView Name="TestTreeView">
            <TreeView.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=Key}"/>
                </DataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>

Use below code in code behind to assign sorted dictionary to treeview

XML

SortedDictionary<DateTime, bool> TestDictionary = new SortedDictionary<DateTime, bool>();
                TestDictionary.Add(DateTime.Today, true);
                TestDictionary.Add(DateTime.Now, false);
                TestTreeView.ItemsSource = TestDictionary;
