ClientTarget Class

Defines the alias associated with the target user agent for which ASP.NET server controls should render content. This class cannot be inherited.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)
public sealed class ClientTarget : ConfigurationElement
public final class ClientTarget extends ConfigurationElement
public final class ClientTarget extends ConfigurationElement
Not applicable.

The ClientTarget refers to the add element in the clientTarget section of the configuration file.

ClientTarget belongs to a group that includes the ClientTargetCollection class and the ClientTargetSection class.

The ClientTarget class contains two properties identifying a client browser, also called user agent. One property is the alias associated with the client browser identified by the second property. ASP.NET uses this information to render server controls in a page.

Refer to the ClientTarget to see how the user agent or its alias is used programmatically or to @ Page to see how they are used declaratively.

If the ClientTarget property is not set, the HttpBrowserCapabilities object associated with the Request property reflects the capabilities of the client browser. If the property is set, the client browser detection is disabled and the page will use browser capabilities associated with the user agent string that you define. You can set this property to any valid user agent string.

This section provides two code examples. The first demonstrates how to declaratively specify values for several properties of the ClientTarget class. The second shows how to obtain the ClientTargetCollection object from the configuration file. You use this object to access the ClientTarget objects it contains.

The following code example shows how to declaratively specify values for several properties of the ClientTarget class.

<clientTarget>
  <add alias=
    "ie5" userAgent="Mozilla/4.0 (compatible;MSIE 5.5;Windows NT 4.0)"/>
  <add alias=
    "ie4" userAgent="Mozilla/4.0 (compatible;MSIE 4.0;Windows NT 4.0)"/>
  <add alias=
    "uplevel" userAgent="Mozilla/4.0 (compatible;MSIE 4.0;Windows NT 4.0)"/>
  <add alias="downlevel" userAgent="Unknown"/>
</clientTarget>

The following code example shows how to obtain the ClientTargetCollection object from the configuration file


// Get the Web application configuration.
System.Configuration.Configuration configuration =
    WebConfigurationManager.OpenWebConfiguration(
    "/aspnetTest");

// Get the <clientTarget> section.
ClientTargetSection clientTargetSection =
  (ClientTargetSection)configuration.GetSection(
  "system.web/clientTarget");


// Get the client target collection.
ClientTargetCollection clientTargets =
  clientTargetSection.ClientTargets;
