try using the cloning technique         DataGridViewRow row    DataGridViewRow yourdatagrid Rows 0  Clone           then for each of the values use a loop like below      int cc   yourdatagrid Columns Count      for  int i2   0  i  lt  cc  i2                  row Cells i  Value   yourdatagrid Rows 0  Cells i  Value            yourdatagrid Rows Add row       i              This should work  I m not sure about how the binding works though  Hopefully it won t prevent this from working
