I do not use drag and drop on my mover list boxes, however, this seems to work for disabled items when fired by a button or double click.

*** aryAvailableValues = RowSource
*** AvailableValue = ControlSource

*** Move the hightlighted Available value to the Selected list
*** If Item is Disabled, ignore it
IF SUBSTR(aryAvailableValues(AvailableValue,1),1,1) <> "\"

*** Code to move selected item from one list to the other

ENDIF

>At first, this question looks trivial. However, there is no native property of the listbox, which would tell, if the item is enabled/disabled. The question was arised on Russian VFP Club Forum. My first idea was to check, if the List(i) starts with \. However, according to the person, who asked this question, this doesn't work.

>=================================
>The background of the problem: ListBox is used as the source for Drag&Drop. Once the item is moved, he adds \ to make it disabled. If he puts a mouse cursor on the disabled line and starts to move it, selected(i) returns .t. So, how to find out, that the item is disabled?
