Remarques

Utilisez la BorderColor propriété pour spécifier la couleur de bordure du contrôle serveur Web.Use the BorderColor property to specify the border color of the Web Server control. Cette propriété est définie à l’aide d’un Color objet.This property is set using a Color object.

Notes

La BorderColor propriété est restituée uniquement pour certains contrôles.The BorderColor property will render only for certain controls. Par exemple, les Table contrôles,,, Panel DataGrid Calendar et ValidationSummary affichent cette propriété.For example, the Table, Panel, DataGrid, Calendar, and ValidationSummary controls will render this property. Elle fonctionne également pour les CheckBoxList contrôles, RadioButtonList et DataList , si leur RepeatLayout propriété a la valeur, et RepeatLayout.Table non RepeatLayout.Flow .It will also work for the CheckBoxList, RadioButtonList, and DataList controls, if their RepeatLayout property is set to RepeatLayout.Table, not RepeatLayout.Flow. Toutefois, il est restitué en tant qu' bordercolor attribut, qui ne fait pas partie de la norme HTML 3,2.However, it is rendered as the bordercolor attribute, which is not part of the HTML 3.2 standard. L' bordercolor attribut fonctionne pour Microsoft Internet Explorer version 3,0 ou ultérieure, mais pas pour la plupart des autres navigateurs.The bordercolor attribute works for Microsoft Internet Explorer version 3.0 or later, but not most other browsers.

Lorsque la BorderColor propriété n’est pas définie, le navigateur utilise sa couleur de bordure par défaut.When the BorderColor property is not set, the browser will use its default border color. Reportez-vous à votre navigateur pour déterminer son modèle de couleurs par défaut.Refer to your browser to determine its default color scheme.
