Gets or sets the name of the page theme.

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

[BrowsableAttribute(false)]
public virtual string Theme { get; set; }
<asp:Page Theme="String" />

Property Value

Type: System.String
The name of the page theme.

ExceptionCondition
InvalidOperationException

An attempt was made to set Theme after the PreInit event has occurred.

ArgumentException

Theme is set to an invalid theme name.

The Theme property sets the name of the theme used for the page. If you want the settings on the page to take precedence over the settings in the theme, use the StyleSheetTheme property. For more information, see ASP.NET Themes and Skins.

The Theme property must be set prior to the PreInit event; setting the Theme property after the PreInit event will cause an InvalidOperationException exception.

The specified theme must exist as either an application or a global theme. If the theme does not exist, an HttpException exception is thrown.

  if (ThemeName != null)
  {

  }
}
