using DevExpress.XtraTreeList.Nodes;

// Data source for select (left) images.
treeList1.SelectImageList = imageCollection1;
// Use the data source to assign select images to nodes.
// Data source fields do NOT allow you to specify
// two images that depend on the focus.
// This property has priority over the node's
// ImageIndex and SelectImageIndex properties.
treeList1.ImageIndexFieldName = "ImageIndex";
// Data source for state (right) images.
treeList1.StateImageList = imageCollection1;
// Use the Load event to assign images to nodes.
treeList1.Load += TreeList1_Load;

private void TreeList1_Load(object sender, EventArgs e) {
    foreach (TreeListNode node in treeList1.Nodes) {
        // The left image displayed when the node is NOT focused.
        node.ImageIndex = 0;
        // The left image displayed when the node is focused.
        node.SelectImageIndex = 1;
        // The right image that does not depend on the focus.
        node.StateImageIndex = 2;
    }
