Trying to use the ultratreeview and ultralistview , and drag items from the listiew, dropping into the treeview.
Is this functionality is implemented as part of the controls ? I can't seem to be able to find the way out of the darkness that is UltraControls
Help!
Drag & Drop is generally implemented for each Control.
Start in a MouseDown event handler and use the DoDragDrop method.

Make sure the receiving Control has the AllowDrop property set to true.

I posted a D&D sample to the 10.2A beta forum, I can check later if it's still around.
right, getting there
I can drag from a MS listview to a Telerik treeview . WhooHoo !
now, I also need to drag nodes around within the treeview. However, the dragdrop event is getting fired for the drag (which is understandable) so I need to determine what was the source of the drag
The code I have in this event is
ListViewItem1 = CAST(e:Data:GetData (Progress.Util.TypeHelper:GetType("System.Windows.Forms.ListViewItem")),System.Windows.Forms.ListViewItem) .is there any way of determining the type of the e:Data object ?
is there any way of determining the type of the e:Data object ?
For me it's always enough to rely on the fact, that it implementes IDataObject. So
e:GetDataPresent (Progress.Util.TypeHelper ("FullNameOf.ListViewItem"))
or
e:GetDataPresent (Progress.Util.TypeHelper ("FullNameOf.UltraTreeNode"))
get's me there. That method returns True of False.
