これはSpreadsheetGearグリッド固有の質問です。セルにコメントを追加すると、セルの右上隅に赤い三角形のマーカーが自動的に表示されます。しかし、何か特別なことを示すために、セルの隅に小さな三角形（異なる色）を追加する必要があります。それは可能ですか？

UPATE：これは、ダニエルの提案に基づいて、セルの任意の隅に三角形を追加するために得たものです。

    public void AddTriangleShapeToCorner(IWorksheet worksheet, int row, int col, CellCorners cellCorner)
    {
        const double width = 5, height = 5;
        double xOffset = 0, yOffset = 0;

        IWorksheetWindowInfo windowInfo = worksheet.WindowInfo;

        if (cellCorner == CellCorners.TopRight || cellCorner == CellCorners.BottomRight)
        {
            col++;
            xOffset = width;
        }
        if (cellCorner == CellCorners.BottomLeft || cellCorner == CellCorners.BottomRight)
        {
            row++;
            yOffset = height;
        }
        double top = windowInfo.RowToPoints(row) - yOffset;
        double left = windowInfo.ColumnToPoints(col) - xOffset;

        IShape shape = worksheet.Shapes.AddShape(AutoShapeType.RightTriangle, left, top, width, height);
        shape.Line.Visible = false;         // line at top-left corner is not sharp, so turn it off.
        shape.Placement = Placement.Move;   // make the shape move with cell. NOTE: it doesn't work for top-right and bottom-right corners.
        if (cellCorner == CellCorners.TopLeft || cellCorner == CellCorners.TopRight)
            shape.VerticalFlip = true;
        if (cellCorner == CellCorners.TopRight || cellCorner == CellCorners.BottomRight)
            shape.HorizontalFlip = true;
    }

IShapesAddShapeメソッドを使用できます。タイプには、AutoShapeType.RightTriangleを使用できます。

次に例を示します。

private void AddTriangleShape(SpreadsheetGear.IWorksheet worksheet, int iRow, int iCol)
{
  SpreadsheetGear.IWorksheetWindowInfo windowInfo = worksheet.WindowInfo;

  // Calculate the left, top, width and height of the button by 
  // converting row and column coordinates to points.  Use fractional 
  // values to get coordinates in between row and column boundaries.
  double left = windowInfo.ColumnToPoints(iCol);
  double top = windowInfo.RowToPoints(iRow + 0.5);
  double right = windowInfo.ColumnToPoints(iCol + 0.1);
  double bottom = windowInfo.RowToPoints(iRow + 0.9);
  double width = right - left;
  double height = bottom - top;

  worksheet.Shapes.AddShape(SpreadsheetGear.Shapes.AutoShapeType.RightTriangle, left, top, width, height);
}
