Style.BorderColor Property

Definition

public:
 property System::Drawing::Color BorderColor { System::Drawing::Color get(); void set(System::Drawing::Color value); };
[System.ComponentModel.TypeConverter(typeof(System.Web.UI.WebControls.WebColorConverter))]
[System.ComponentModel.Bindable(true)]
public System.Drawing.Color BorderColor { get; set; }
member this.BorderColor : System.Drawing.Color with get, set
Public Property BorderColor As Color

Property Value

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

Attributes

Examples

This example demonstrates how to use a Style object to change the style properties of multiple controls at once. Each time one of the Style property values changes, each control must call its ApplyStyle method. Note that not all the controls included support all the properties demonstrated. If a control does not support a particular property, the appearance of the control will not change when the property value is changed.

Note

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Forms Page Code Model.

Remarks

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

Note

This property will render only for certain controls. For example, Table, Panel, DataGrid, Calendar, and ValidationSummary will render this property. It will also work for CheckBoxList, RadioButtonList, and DataList if their RepeatLayout property is RepeatLayout.Table and not RepeatLayout.Flow. However, it is rendered as the bordercolor attribute, which may not work in all browsers.
