In other words, use the -1 to prevent apply the color on the node's background/foreground. Use the BackColorValue property to specify the background color of the node's value. Use the SelBackColor, SelForeColor, SelBackColorChild and SelForeColorChild properties to customize the colors for selected nodes. Use the <bgcolor> built-in HTML format to specify a background color for parts of the node's value or name. Use the ForeColorChild property to specify the child node's foreground color.
