The following topics detail how to customize the C1TreeView control's layout and appearance. You can use built-in layout options to lay your controls out in panels such as Grids or Canvases. Themes allow you to customize the appearance of the treeview and take advantage of WPF's XAML-based styling.
You can customize the appearance of your treeview item by using the Header property. You can set the Header to be any object such as a stack panel containing an image and some text:
<C1TreeViewItem>
<C1:C1TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Source="myImage,jpg"/>
<TextBlock Text="My Text"/>
</StackPanel>
</C1:C1TreeViewItem.Header>
</C1:C1TreeViewItem>
