I am trying to put a left and right border on all cells in a row. To do this, I have created two classes: MonthlyBorderRow and BorderCell. I got most of the code from the Puzzle sample from Xceed. However, for some reason only the first cell in each row is getting the border. To set the created class as the template, I am using this line:
grdMonthly.DataRowTemplate = new MonthlyBorderRow();
I welcome any suggestions or ideas. Please let me know if you need anything else.

public MonthlyBorderRow(RowSelector rowSelector)
: base(rowSelector)
{
}
// This constructor is use for creating a new ImageRow by cloning the

// We must add all the code here to copy the properties of that class.
// It is called each time the grid needs to create new DataRow objects from the DataRowTemplate
protected MonthlyBorderRow(MonthlyBorderRow template)
: base(template)
{
}
// Called when we need to create a cell for this row (When adding a column to the grid for example).

{
return new BorderCell(parentColumn);
}
// Creates a clone of a ImageRow object and returns a reference to the
// newly created row.

public class BorderCell : DataCell
{

Pen pen = new Pen(GridControl.GridLinePen.Color, 2);
Point point = new Point(e.DisplayRectangle.X + 1, e.DisplayRectangle.Y);
