C1TreeView Structure

The C1TreeView class is a StackPanel with two elements:

A header that represents the actual node, with a button to collapse and expand the children.
A body that is another StackPanel and contains other nodes.

You can add images to a node by grabbing its first child (the header), casting that to a StackPanel, and inserting an image element at whatever position you prefer. For example:

Visual Basic	Copy Code
Dim nodeHeader As StackPanel = TryCast(TreeNode.Children(0), StackPanel) nodeHeader.Children.Insert(0, myImage)

C#	Copy Code
StackPanel nodeHeader = TreeNode.Children[0] as StackPanel; nodeHeader.Children.Insert(0, myImage);
