ScrollBar.Scroll Event


Occurs one or more times as content scrolls in a ScrollBar when the user moves the Thumb by using the mouse.

 event System::Windows::Controls::Primitives::ScrollEventHandler ^ Scroll;
public event System.Windows.Controls.Primitives.ScrollEventHandler Scroll;
member this.Scroll : System.Windows.Controls.Primitives.ScrollEventHandler 
Public Custom Event Scroll As ScrollEventHandler 


The following example shows how assign an event handler for the Scroll event to a ScrollBar control, and how to define the event handler in code.

<ScrollBar Orientation="Horizontal"/>
private void OnScroll(object sender, RoutedEventArgs e)
   //Things to do when the Scroll event occurs
Private Sub OnScroll(ByVal sender As Object, ByVal e As RoutedEventArgs)
   'Things to do when the Scroll event occurs
End Sub


This event typically occurs multiple times when the user changes the Value of the ScrollBar by dragging the Thumb. There is no limit to the number of times this event is raised as the Thumb position is dragged.

This event is not raised when the Value of the ScrollBar control is changed in code.
