Hi,

I am trying to implement drag & drop on a treeview control. I am using VFP 7.0 with MS Treeview Control 6.0 (SP4).

I am implementing the following methods:

Treeview::OLEStartDrag

*** ActiveX Control Event ***
LPARAMETERS data, allowedeffects

this.selectedItem = null

Treeview::OLEDragOver

*** ActiveX Control Event ***
LPARAMETERS data, effect, button, shift, x, y, state

IF ISNULL(this.selectedItem)
  this.selecteditem = this.hittest(x, y)
ENDIF

this.dropHighlight = this.hitTest(x, y)

The main drag & drop funtionality is working properly, but the method OLEDragOver, which is intented to highlight the nodes as the user passes the mouse over them while dragging is not highlighting the nodes.

Does anyone has any hint?
