Lparameters oDataObject, nEffect oDataObject.ClearData oDataObject.SetFormat("Rapid DeleteCollect") && Delete the Rapid Collection AddressThis enables me to identify what is being dragged to the screen for deletion. However the DataObject of the TreeView seems to work differently and I can't figure out now I indicate what is being Dragged (The SetFormat is not available within the TreeView) can anybody point me in the right direction.
