OnItemStyleChanged Method






Leadtools.Windows.Controls Namespace > ImageList Class : OnItemStyleChanged Method
A RoutedPropertyChangedEventArgs that contains the event data.
Raises the ItemStyleChanged event.
Syntax
protected virtual void OnItemStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListItemStyle> e
)
'Declaration
 
Protected Overridable Sub OnItemStyleChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of ImageListItemStyle) _
) 
'Usage
 
Dim instance As ImageList
Dim e As RoutedPropertyChangedEventArgs(Of ImageListItemStyle)
 
instance.OnItemStyleChanged(e)

            

        

            

            

            

        

            

            
protected:
virtual void OnItemStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListItemStyle>^ e
) 

            

        

            

        
            
Parameters
e


A RoutedPropertyChangedEventArgs that contains the event data.

            
            

            
            
            
            
Remarks
Raising an event invokes the event handler through a delegate.



The OnItemStyleChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.



Notes to Inheritors: When overriding OnItemStyleChanged in a derived class, be sure to call the base class's OnItemStyleChanged method so that registered delegates receive the event.
