You can add a new cell in RowDataBound event of the gridview, like below. (I have added the comments where needed)

protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
   {
     TableHeaderCell NewCell = new TableHeaderCell();
     NewCell.Text = "Header Text";
     e.Row.Cells.AddAt(4(Index of Cell where you want to add cell), NewCell);
   }


if (e.Row.RowType == DataControlRowType.DataRow)
     {
       TableCell NewCell= new TableCell(); 
       NewCell.ID = "NewCell";
       NewCell.Text = "Text value of cell which you want to display";
       e.Row.Cells.AddAt(4, NewCell);
     }
 }

create a method to add columns in user control, and keep it accessor public. Now call that function from the aspx page where you have you that control object.
