# 一、实现效果 #

# 二、 实现方法 #

## 2.1、创建复合表头 ##

①将创建的GridControl下的GirdView1转化为BandGridView类型；

②创建需要展示的列（指定列的名称【Name】、描述【caption】、数据字段名称【FieldName】）

③绑定列实现复合表头。

**注意：如果复合表头有多行，则需要设置新增Band的Row Count，然后设置【Band properties下的AutoFillDown=false】**

详细操作如下：

注意：如果要隐藏表格的设计字段内容，则需要将【Views-->bandedGridView1-->OptionsView】下的【**ShowColumnHeaders**和**ShowGroupPanel**】属性设置为：**False**。

## 2.2、设置多行表头背景颜色、表格边框颜色 ##

/// <summary>
            /// 设置表格标题背景颜色
            /// </summary>
            /// <param name="gridView">BandedGridView组件</param>
            /// <param name="startColumnIndex">开始列索引</param>
            /// <param name="endColumnIndex">结束列索引</param>
            /// <param name="color">背景颜色</param>
            public static void SetGridViewHeaderBackColor(BandedGridView gridView,
                int startColumnIndex, int endColumnIndex, Color color)
            {
                if (gridView != null && startColumnIndex >= 0 && endColumnIndex > 0)
                {
                    for (int i = startColumnIndex; i <= endColumnIndex; i++)
                    {
                        GridBand curGridBand = gridView.Bands[i];
                        curGridBand.AppearanceHeader.BackColor = color;
                        if (curGridBand.Children.View.Bands.Count > 0)
                        {
                            foreach (GridBand item in curGridBand.Children)
                            {
                                item.AppearanceHeader.BackColor = color;
                            }
                        }
                    }
                }
            }
    
    
            /// <summary>
            /// 设置表格单元格边框颜色
            /// </summary>
            /// <param name="gridView">GridView组件</param>
            /// <param name="color">需设置的颜色</param>
            /// <param name="isSetting">是否设置</param>
            public static void SetGridViewBorderLineBackColor(GridView gridView, Color color, bool isSetting = true)
            {
                //获取表格边框原来的颜色
                Color originalColor = gridView.Appearance.VertLine.BackColor;
                gridView.BorderStyle = DevExpress.XtraEditors.Controls.BorderStyles.Simple;
                if (isSetting)
                {
                    gridView.Appearance.VertLine.BackColor = color;
                    gridView.Appearance.HorzLine.BackColor = color;
                    gridView.Appearance.VertLine.Options.UseBackColor = isSetting;
                    gridView.Appearance.HorzLine.Options.UseBackColor = isSetting;
                }
                else
                {
                    gridView.Appearance.VertLine.BackColor = originalColor;
                    gridView.Appearance.HorzLine.BackColor = originalColor;
                    gridView.Appearance.VertLine.Options.UseBackColor = isSetting;
                    gridView.Appearance.HorzLine.Options.UseBackColor = isSetting;
                }
    
            }

## 2.3、使用示例 ##

//修改复合表头的背景颜色
    SetGridViewHeaderBackColor(bandedGridView1,0,bandedGridView1.Bands.Count-1,Color.FromArgb(0,68,176));
    
    //修改表格单元格边框颜色
    SetGridViewBorderLineBackColor(bandedGridView1,Color.Blue,true);
