Answer 1

There are lot of ways to achieve this. The simplest that comes in my mind is:

-Create an istance of GetDataForm and call a method which displays the form and get the result:

GetDataForm form2 = new GetDataForm();
List<DataGridViewRow> res = form2.ShowForm();
for (int i = 0; i < res.Count; i++)
    mainFormGrid.Rows.Add(res[i]);

-In your GetDataForm you should have the following method:

bool _closedByTransferButton = false;
public List<DataGridViewRow> ShowForm() 
{ 
   ShowDialog();
   List<DataGridViewRow> res = new List<DataGridViewRow>();
   if(_closedByTransferButton)
   {
       for(int i = 0;i<grid.Rows.Count;i++)
           if((bool)grid.Rows[i].Cells["checkboxColumn"].Value)
               res.Add(grid.Rows[i]);
   }
   return res;
}

-And the Click event of your Transfer button should be:

private void tranferButton_Click(object sender, EventArgs e)
{
   _closedByTransferButton = true;
   Close();
}

Hope this helps.
