You need to do RemoveObject() and AddObject from the column level, not the grid, even though you mention the column in the string, try something like

For each loGrdColumn in Thisform.MyGrid.Columns
   lcCurContrl = loGrdColumn.CurrentControl
   if not empty( lcCurControl )
     loGrdColumn.RemoveObject( lcCurContrl )
   endif

   loGrdColumn.AddObject( "textbase1", "yourtextboxcontrol" )
EndFor
