  • Article

Namespace: Microsoft.Uii.HostedApplicationToolkit.DataDrivenAdapter
Assembly: Microsoft.Uii.HostedApplicationToolkit.DataDrivenAdapter (in Microsoft.Uii.HostedApplicationToolkit.DataDrivenAdapter.dll)

Usage

'Usage
Dim instance As DataDrivenAdapterBase
Dim eventName As String
Dim controlName As String
Dim listenerCallback As EventHandler(Of ControlChangedEventArgs)
Dim returnValue As Boolean

returnValue = instance.UnregisterEventListener(eventName, controlName, listenerCallback)

Syntax

'Declaration
Public MustOverride Function UnregisterEventListener ( _
    eventName As String, _
    controlName As String, _
    listenerCallback As EventHandler(Of ControlChangedEventArgs) _
) As Boolean

public abstract bool UnregisterEventListener (
    string eventName,
    string controlName,
    EventHandler<ControlChangedEventArgs> listenerCallback
)

public:
virtual bool UnregisterEventListener (
    String^ eventName, 
    String^ controlName, 
    EventHandler<ControlChangedEventArgs^>^ listenerCallback
) abstract

public abstract boolean UnregisterEventListener (
    String eventName, 
    String controlName, 
    EventHandler<ControlChangedEventArgs> listenerCallback
)

public abstract function UnregisterEventListener (
    eventName : String, 
    controlName : String, 
    listenerCallback : EventHandler<ControlChangedEventArgs>
) : boolean

Parameters

  • eventName
    Specifies the name of the event.
  • controlName
    Specifies the control name. Event listener registration can be scoped at the data-driven adapter control level (specify blank or null to omit).
  • listenerCallback
    Callback associated with the listener.

Return Value

Returns true if the unregistration was successful (duplicate unregistration attempts return false).

Exceptions

Exception type Condition
ArgumentNullException

eventName and listenerCallback must not be null.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
