BorderStyleProperties.setBorderColor

Sets border color. This is equivalent to the CSS border-color property, and any valid value for this CSS property can be used when setting a value. Setting this property to null removes any existing value.

Note that for a border to be visible, a border width property and the borderStyle property is also required.

Examples:

 controls.PANEL1.borderColor = "black";
 controls.PANEL1.borderWidth = "2px";
 controls.PANEL1.borderStyle = "solid";
 controls.TEXT1.setBorderColor("#ff00ff");
