Represents the style of a Web server control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

The Style class encapsulates the properties that control the appearance of a Web server control and can be applied to multiple Web server controls to provide a common appearance. You can specify the background color and font color of a control by setting the BackColor and ForeColor properties, respectively. On controls that can display a border, you can control the border width, the border style, and the border color by setting the BorderWidth, BorderStyle, and BorderColor properties. The size of a Web server control can also be specified by using the Height and Width properties.

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.


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 Page Code Model.
