分享Winform datagridview 动态生成中文HeaderText

缘起

很久以前给datagridview绑定列的时候都是手动的，记得以前用Display自定义属性来动态给datagridview绑定列。后来发现不行，于是还在博问发了问题：

后来热心网友帮我回答了这个问题，一试还真可以。再次记录一下。

测试流程：

1) View Entity:

 /// <summary>
    /// IPC完工成品情况查询实体
    /// </summary>
    public class GdvSourceProductRpt
    {
        [DisplayName("客户名称")]
        public string custerName { get; set; }
        [DisplayName("成品订单号")]
        public string orderNo { get; set; }

        [DisplayName("产品名称")]
        public string InvName { get; set; }

        [DisplayName("制令")]
        public string mo_code { get; set; }

        [DisplayName("物料号")]
        public string goods_code { get; set; }

        [DisplayName("订单量")]
        public int order_count { get; set; }

        [DisplayName("制令数")]
        public int mo_count { get; set; }

        [DisplayName("成品产量")]
        public int scanNum { get; set; }

        [ProgressBarCell(Style = 1)]
        [DisplayName("完成度")]
        public double rate { get; set; }
    }

 2)DataGridView的DataSource设置为窗体里的 BindingSource，DataGridView自动完成中文列名的显示

这个是手工操作按下不表

3)实现动态绑定列，实现多个数据源在一个DataGridView里显示

 /// <summary>
        /// 动态绑定DataGridView的列
        /// </summary>
        /// <param name="t"></param>
        /// <param name="dgv"></param>
        protected virtual void BingGridColumn(Type t,DataGridView dgv)
        {
            dgv.Columns.Clear();
            var props = t.GetProperties().Where(prop => prop.GetCustomAttributes(typeof(DisplayNameAttribute), false).Any());
            int col_width = dgv.Width / props.Count() - 8;
            foreach (var prop in props)
            {
                DisplayNameAttribute attrib = (DisplayNameAttribute)prop.GetCustomAttributes(typeof(DisplayNameAttribute), false).FirstOrDefault();
                if (prop.GetCustomAttributes(typeof(ProgressBarCellAttribute), false).Any())
                {
                    DataGridViewProgressBarColumn dc = new DataGridViewProgressBarColumn();
                    dc.Name = "col" + prop.Name;
                    dc.HeaderText = attrib.DisplayName;
                    dc.DataPropertyName = prop.Name;
                    dc.Width = col_width; 
                    dgv.Columns.Add(dc);
                }
                else
                {
                    DataGridViewTextBoxColumn dc = new DataGridViewTextBoxColumn();
                    dc.Name = "col" + prop.Name;
                    dc.HeaderText = attrib.DisplayName;
                    dc.DataPropertyName = prop.Name;
                    dc.Width = col_width;
                    dgv.Columns.Add(dc);
                }
            }
        }

顺便贴一下代码，如何实现DataGridView进度条列。

 

 public class DataGridViewProgressBarCell : DataGridViewCell
    {
        public DataGridViewProgressBarCell()
        {
            this.ValueType = typeof(decimal);
        }

        //设置进度条的背景色；
        public DataGridViewProgressBarCell(Color progressBarColor)
            : base()
        {
            ProgressBarColor = progressBarColor;
        }

        protected Color ProgressBarColor = Color.Green; //进度条的默认背景颜色,绿色；
        protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
        {
            using (SolidBrush backBrush = new SolidBrush(cellStyle.BackColor))
            {
                graphics.FillRectangle(backBrush, cellBounds);
            }
            base.PaintBorder(graphics, clipBounds, cellBounds, cellStyle, advancedBorderStyle);
            using (SolidBrush brush = new SolidBrush(ProgressBarColor))
            {
                if (value == null)
                    value = 0;
                decimal num = System.Convert.ToDecimal(value);
                float percent = (float)(num / System.Convert.ToDecimal(100));
                graphics.FillRectangle(brush, cellBounds.X, cellBounds.Y + 1, cellBounds.Width * percent, cellBounds.Height - 3);
                string text = string.Format("{0}%", num);
                SizeF rf = graphics.MeasureString(text, cellStyle.Font);
                float x = cellBounds.X + (cellBounds.Width - rf.Width) / 2f;
                float y = cellBounds.Y + (cellBounds.Height - rf.Height) / 2f;
                Color txtColor = Color.Lime;
                if (System.Convert.ToDecimal(value) < 10)
                    txtColor = Color.OrangeRed;
                if (System.Convert.ToDecimal(value) < 50 && System.Convert.ToDecimal(value) > 20)
                    txtColor = Color.DarkBlue;
                graphics.DrawString(text, cellStyle.Font, new SolidBrush(txtColor), x, y);
            }
        }
    } 

 

 public class DataGridViewProgressBarColumn : DataGridViewColumn
    {
        public DataGridViewProgressBarColumn()
            : base(new DataGridViewProgressBarCell())
        {
            CellTemplate = new DataGridViewProgressBarCell();
        }
    }
