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

Usage

'Usage
Dim instance As WebDataDrivenAdapter
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 Overrides Function UnregisterEventListener ( _
    eventName As String, _
    controlName As String, _
    listenerCallback As EventHandler(Of ControlChangedEventArgs) _
) As Boolean

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

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

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

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

Parameters

• eventName
