This property allows specifying text displaying as a title of a vector item. Also it allows using attributes to show them inside the title.
This example demonstrates how to customize shape title options. To do this, customize the required properties from the following list.
ShapeTitleOptions.Pattern - specifies the Pattern used to construct title text.
ShapeTitleOptions.TextColor - specifies the title text color.
ShapeTitleOptions.TextGlowColor - specifies the glow color for the title text.
ShapeTitleOptions.Visibility - specifies title visibility.
