MobileCapabilities.HasCapability(String, String) MobileCapabilities.HasCapability(String, String) MobileCapabilities.HasCapability(String, String) MobileCapabilities.HasCapability(String, String) Method

Definition

Provides a uniform way to evaluate device capabilities. This method is used internally by ASP.NET to implement various device-selection criteria expressed in the syntax of the controls. For example, this method is used to choose among <Choice> Element (.NET Framework Developer's Guide) elements in a DeviceSpecific/Choice construct. This API is obsolete. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

public:
 bool HasCapability(System::String ^ delegateName, System::String ^ optionalParameter);
public bool HasCapability (string delegateName, string optionalParameter);
member this.HasCapability : string * string -> bool
Public Function HasCapability (delegateName As String, optionalParameter As String) As Boolean

Parameters

delegateName
String String String String

The device evaluation method, property name, or item in the capabilities collection.

optionalParameter
String String String String

The optional argument.

Returns

true if the device has the specified capability; otherwise, false.

Exceptions

A capabilityName parameter is not found as a device-filter name specified in the configuration file, as a MobileCapabilities property, or as an item in the MobileCapabilities Item collection.

Remarks

Applications can use the HasCapability method programmatically when they gather device-specific information. If the capabilityName parameter specifies a device evaluation method, the optionalArgument parameter is passed to this method. If the capabilityName parameter specifies a property name or item in the capabilities dictionary, the HasCapability method checks whether the property or item is equal to the optionalArgument parameter.
