Property Value

Type: System.DrawingColor
A Color that represents the border color of the control. The default is Empty, which indicates that this property is not set.
Remarks

Use the BorderColor property to specify the border color of the Web Server control. This property is set using a Color object.

NoteNote

The BorderColor property will render only for certain controls. For example, the Table, Panel, DataGrid, Calendar, and ValidationSummary controls will render this property. It will also work for the CheckBoxList, RadioButtonList, and DataList controls, if their RepeatLayout property is set to RepeatLayout.Table, not RepeatLayout.Flow. However, it is rendered as the bordercolor attribute, which is not part of the HTML 3.2 standard. The bordercolor attribute works for Microsoft Internet Explorer version 3.0 or later, but not most other browsers.

When the BorderColor property is not set, the browser will use its default border color. Refer to your browser to determine its default color scheme.

Examples

The following example illustrates how to set the BorderColor property of the Table control, which is inherited from the WebControl base class.
