  Hi David,

  You can create custom GridCellFactory for the FlexGrid and override its PrepareCell method to increase the thickness of last row and last column borders. Here is the code snippet to do so:

  public override void PrepareCell(GridCellType cellType, GridCellRange range, GridCellView cell, Thickness internalBorders)
  {
      if (range.Row == Grid.Rows.Count - 1)
      {
          // For the last row, increase the bottom border by 3
          internalBorders = new Thickness(
              internalBorders.Left,
              internalBorders.Top,
              internalBorders.Right,
              internalBorders.Bottom + 3
          );
      }
      if(range.Column == Grid.Columns.Count - 1)
      {
          // For the last row, increase the right border by 2
          internalBorders = new Thickness(
              internalBorders.Left,
              internalBorders.Top,
              internalBorders.Right + 2,
              internalBorders.Bottom
          );
      }
      base.PrepareCell(cellType, range, cell, internalBorders);
  }

  Kindly refer to the attached sample for full implementation. See WpfFlex.zip

  Thanks & regards,
