Utilice la BorderColor propiedad para especificar el color de borde del control Servidor web. Esta propiedad se establece mediante un Color objeto .
Nota
La BorderColor propiedad solo se representará para determinados controles. Por ejemplo, los Tablecontroles , Panel, CalendarDataGrid, y ValidationSummary representarán esta propiedad. También funcionará para los CheckBoxListcontroles , RadioButtonListy DataList , si su RepeatLayout propiedad está establecida RepeatLayout.Tableen , no RepeatLayout.Flowen . Sin embargo, se representa como el bordercolor atributo , que no forma parte del estándar HTML 3.2. El bordercolor atributo funciona para Microsoft Internet Explorer versión 3.0 o posterior, pero no para la mayoría de los demás exploradores.
Cuando no se establece la BorderColor propiedad, el explorador usará su color de borde predeterminado. Consulte el explorador para determinar su combinación de colores predeterminada.
