Tree view have a lot of customization options available. try using
LevelStyles / LeafNodeStyle / NodeStyle / ParentNodeStyle / RootNodeStyle etc tags.

you can set different colors and Font using above properties.

These Properties are available for the TreeView in System.Web.UI.WebControls. Not available for the WinForms TreeView.

you can change the color and font using below code.

Treeview.Nodes[0].backcolor = color.blue;
Treeview.Nodes[0].Nodefonts = your font;

however in your case you need to find the index of the Right node using your own logic.

Solution 2

you can change the color and font using below code.

C#

Treeview.Nodes[0].backcolor = color.blue;
Treeview.Nodes[0].Nodefonts = your font;

however in your case you need to find the index of the Right node using your own logic.

To enumerate all the TreeNodes in the Win Forms TreeView, and assign different BackColor and Font based on their level in the TreeView:

C#

private List<Color> colorList = new List<Color>
{
    // or use Color.AliceBlue 
    // or Color.FromArgb(red value, green value, blue value)
    Color.FromArgb(0xfff1de), 
    Color.FromArgb(0xdbe7eb),
    Color.FromArgb(0xf2f1eb)
};

private List<Font> fontList = new List<Font>
{
    new System.Drawing.Font("Arial", 10.8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0))),
    new System.Drawing.Font("Arial", 10.2F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0))),
    new System.Drawing.Font("Arial", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)))
};

private void Form1_Load(object sender, EventArgs e)
{
    // other Load Event business ...

    // recursively enumerate the TreeNodes
    colorTreeViewNodes(treeView1.Nodes);
}

private void colorTreeViewNodes(TreeNodeCollection theNodes)
{
    foreach (TreeNode theNode in theNodes)
    {
        theNode.BackColor = colorList[theNode.Level];
        theNode.NodeFont = fontList[theNode.Level];

        if (theNode.Nodes.Count > 0) colorTreeViewNodes(theNode.Nodes);
    }
}

This code uses the 'Level property of each TreeNode as an index into the lists of Colors and Fonts.
