C#

'Declaration
 
Protected Overrides Sub OnMouseWheel( _
   ByVal evt As MouseEventArgs _
)

   MouseEventArgs evt
)

Remarks

This method makes sure the LastInput property value has up-to-date information describing this mouse input event. It then calls DoMouseWheel to allow tools to handle the input event, and then finally calls the base method to invoke all of the MouseWheel event handlers.

Requirements
