The default behavior of the mouse wheel is to scroll through drop-down lists on the validation form.

A new property (EnableDropdownScroll) has been added to the Project object that controls the scrolling behavior of drop down lists on the validation form.

This property can be accessed via script and can be used in the Application_InitializeBatch event and the Application_InitializeScript event.

The default value for this property is True, which means that there is no change to the current behavior. When the value for this property is set to False, the scrolling of a mouse wheel no longer controls a simple field drop-down list, even if a list is selected. Instead, if the mouse is over the validation form, scrolling the mouse wheel moves the validation form up and down if it spans more than one page on the screen. If the mouse is over the image in the Viewer, scrolling the mouse wheel zooms in and out on the image.

The following code examples shows this property used in script:

Private Sub Application_InitializeBatch(ByVal pXRootFolder As CASCADELib.CscXFolder)
   Project.EnableDropdownScroll = False
End Sub

Private Sub Application_InitializeScript()
   Project.EnableDropdownScroll = False
End Sub
