Comentarios
Utilice la HorizontalPadding propiedad para controlar la cantidad de espacio horizontal alrededor del texto del nodo al que se aplica .TreeNodeStyle Este espacio se inserta entre el borde izquierdo del texto y el borde del área de texto, así como entre el borde derecho del texto y el borde del texto. Para controlar el espaciado vertical, use la VerticalPadding propiedad .
