DevExpress开发中bandedGridView的特殊上下标设置

DevExpress开发项目中，GridView和bandedGridView的列标题经常需要显示一些带有下标或上标的文字，如下图所示：

如果上标是平方或是立方，可以通过输入法完成，平方（二次方）如下所示：

同样，立方（三次方）也是一样的方法，不在赘述。但对于下标和其他的一些上标，则可用如下方法进行：

// 表头设置
private void bandedGridView1_CustomDrawBandHeader(object sender, DevExpress.XtraGrid.Views.BandedGrid.BandHeaderCustomDrawEventArgs e)
{
    DrawBandHeader("Test", null, "1", "gridBand1", sender, e);
    DrawBandHeader("Test", "1", null, "gridBand2", sender, e);
    DrawBandHeader("Test", "1", "1", "gridBand3", sender, e);
}

/// <summary>
/// 重绘Band名称
/// </summary>
/// <param name="strBase">底数</param>
/// <param name="subStr">下标</param>
/// <param name="supStr">上标</param>
/// <param name="bandName">GridBand名称</param>
/// <param name="sender"></param>
/// <param name="e"></param>
private void DrawBandHeader(string strBase, string subStr, string supStr, string bandName, object sender, DevExpress.XtraGrid.Views.BandedGrid.BandHeaderCustomDrawEventArgs e)
{
    if (!e.Band.Name.Equals(bandName))
        return;

    float startX = (e.Bounds.Left + e.Bounds.Right) / 2;
    float startY = e.Bounds.Top;
    e.Info.Caption = "";
    e.Painter.DrawObject(e.Info);

    // 绘制底数
    Font baseFont = new Font(e.Appearance.Font.OriginalFontName, e.Appearance.Font.Size);
    e.Graphics.DrawString(strBase, baseFont, Brushes.Black, startX, startY);

    // 求上标或下标起点的参考位置
    startX += e.Graphics.MeasureString(strBase, baseFont).Width - 2;
    
    // 上下标大小字体
    Font scriptFont = new Font(e.Appearance.Font.OriginalFontName,
                    e.Appearance.Font.Size - 3);
    // 绘制下标
    if (subStr != null)
    {
        e.Graphics.DrawString(subStr, scriptFont, Brushes.Black, startX, startY + 9);
    }

    // 绘制上标
    if (supStr != null)
    {
        e.Graphics.DrawString(supStr, scriptFont, Brushes.Black, startX, startY + 2);
    }
    
    e.Handled = true;
}

// 列标题设置
private void bandedGridView1_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e)
{
    DrawColHeader("Game", null, "1", "bandedGridColumn1", sender, e);
    DrawColHeader("Game", "1", null, "bandedGridColumn2", sender, e);
    DrawColHeader("Game", "1", "1", "bandedGridColumn3", sender, e);
}

/// <summary>
/// 重绘列标题
/// </summary>
/// <param name="strBase">底数</param>
/// <param name="subStr">下标</param>
/// <param name="supStr">上标</param>
/// <param name="colName">列名</param>
/// <param name="sender"></param>
/// <param name="e"></param>
private void DrawColHeader(string strBase, string subStr, string supStr, string colName, object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e)
{
    if (e.Column != null && !e.Column.Name.Equals(colName))
        return;

    float startX = (e.Bounds.Left + e.Bounds.Right) / 2;
    float startY = e.Bounds.Top;
    e.Info.Caption = "";
    e.Painter.DrawObject(e.Info);

    // 绘制底数
    Font baseFont = new Font(e.Appearance.Font.OriginalFontName, e.Appearance.Font.Size);
    e.Graphics.DrawString(strBase, baseFont, Brushes.Black, startX, startY);

    // 求上标或下标起点的参考位置
    startX += e.Graphics.MeasureString(strBase, baseFont).Width - 2;

    // 上下标大小字体
    Font scriptFont = new Font(e.Appearance.Font.OriginalFontName,
        e.Appearance.Font.Size - 3);
    // 绘制下标
    if (subStr != null)
    {
        e.Graphics.DrawString(subStr, scriptFont, Brushes.Black, startX, startY + 9);
    }

    // 绘制上标
    if (supStr != null)
    {
        e.Graphics.DrawString(supStr, scriptFont, Brushes.Black, startX, startY + 2);
    }

    e.Handled = true;
}

 实现效果如下如所示，可根据需要替换上下标内容：
