Customize appearance for every node

Generally, Flexible TreeView allows you to define the node control appearance for all nodes at one time. To be able to define different node control`s appearance for every node you need to override these node control methods:

• GetFont – to change the node control font for every node;
• GetTextColor - to change the node control`s text color for every node;
• GetTitleFont – to change the expandable node control`s title font;
• GetTitleColor – to change the expandable node control`s title color;
• GetDescriptionFont – to change the NodeExpandableTextBox`s description font;
• GetDescriptionColor – to change the NodeExpandableTextBox`s description color.

To do that, you need to inherit your new node control class from the built-in one, override one of these methods and install this node control into a treeview as shown below:

// The node control which displays a bold text when node is selected or focused.
class MyNodeTextBox : NodeTextBox
{
  public override Font GetFont(Node pNode, DrawContext pContext)
  {
    Font font = base.GetFont(pNode, pContext);
    if (pNode.IsSelected)
    {
      font = new Font(font, FontStyle.Bold);
    }
    return font;
  }
}
 
// use our new node control.
MyNodeTextBox tb = new MyNodeTextBox();
tb.AttachTo(tree);
