I gave Hans Passant the Check mark since he answered the question asked... However, I went another route for the solution. Since the dialog box is modal, the list of items will not change from the time it is created. So I am able to call the code below to ensure that the textboxes are in the correct location when the dialog first displays.

  /// 

  /// Horizontally shifts the label and text boxes that display the total
  /// values so that the totals remain aligned with the columns.
  /// 
  private void ShiftTotalsDisplay(DataGridView grid, Label firstLabel,
     TextBox secondTextBox, TextBox thirdTextBox)
  {         
     //Note if you have a rowheader add the width here also.
     int nameRightLoc = grid.Location.X +            
        grid.Columns[0].Width;
     int fpRightLoc = nameRightLoc +
        grid.Columns[0].DividerWidth +
        grid.Columns[1].Width;
     int dlRightLoc = fpRightLoc + 
        grid.Columns[1].DividerWidth +
        grid.Columns[2].Width;

     Point loc = firstLabel.Location;
     loc.X = nameRightLoc - firstLabel.Width - 2;
     firstLabel.Location = loc;

     loc = secondTextBox.Location;
     loc.X = fpRightLoc - secondTextBox.Width - 2;
     secondTextBox.Location = loc;

     loc = thirdTextBox.Location;
     loc.X = dlRightLoc - thirdTextBox.Width - 2;
     thirdTextBox.Location = loc;         
  }
