vb.net - Determine if DataGridView Row being Dragged over Treeview -

how determine if item i'm dragging datagridview treeview datagridview row?

i have treeview has ability drag , drop itself, want put check in treeview dragover check see if treenode or datagridview row.

i know can check if treeview node doing..

if e.data.getdatapresent("system.windows.forms.treenode", true) = false exit sub 

but tried doing..

if e.data.getdatapresent("system.windows.forms.datagridviewrow", true) = false exit sub 

but isn't working me. i'm not sure i'm doing wrong?

private sub datagridview1_mousedown(byval sender object, byval e mouseeventargs) handles datagridview1.mousedown         if datagridview1.currentrow nothing exit sub          if e.button = mousebuttons.left , datagridview1.currentcell.columnindex >= 0              drageditemtext = datagridview1.rows(datagridview1.currentcell.rowindex).cells(0).value.tostring             drageditemext = datagridview1.rows(datagridview1.currentcell.rowindex).cells(1).value.tostring             drageditemrowindex = datagridview1.currentcell.rowindex              datagridview1.dodragdrop(drageditemtext, dragdropeffects.copy) end sub   public sub treeview1_dragenter(byval sender system.object, byval e system.windows.forms.drageventargs)         e.effect = dragdropeffects.copy         if e.data.getdatapresent("system.windows.forms.datagridviewrow", true)             console.writeline("datagridviewrow")             e.effect = dragdropeffects.move             exit sub         end if         'see if there treenode being dragged         if e.data.getdatapresent("system.windows.forms.treenode", true)             'treenode found allow move effect             e.effect = dragdropeffects.move         else             'no treenode found, prevent move             e.effect = dragdropeffects.none         end if      end sub 

you sending text, not row.

try this:

datagridview1.dodragdrop(datagridview1.currentrow, dragdropeffects.copy)
