WinForm控件小知识

1.DataGridView控件显示自定义表

            //造个数据表
            DataTable dt = new DataTable();
            dt.Columns.Add("DEcode", System.Type.GetType("System.String"));
            dt.Columns.Add("DEname", System.Type.GetType("System.String"));
            dt.Columns.Add("DEunit", System.Type.GetType("System.String"));
            dt.Columns.Add("DEliang", System.Type.GetType("System.Double"));
            dt.Columns.Add("DEprice", System.Type.GetType("System.Double"));
            dt.Columns.Add("DEtotal", System.Type.GetType("System.Double"));
            DataRow dr = dt.NewRow();
            dr["DEcode"] = tab[].Code;
            dr["DEname"] = tab[].Name;
            dr["DEunit"] = tab[].Unit;
            dr["DEliang"] = ;
            dr["DEprice"] = tab[].Price;
            dr["DEtotal"] = Convert.ToDouble(dr["DEliang"]) * Convert.ToDouble(dr["DEprice"]);
            dt.Rows.Add(dr);
            //不自动显示数据源中的列名
            YuSuanBiaoDGV.AutoGenerateColumns = false;
            YuSuanBiaoDGV.DataSource = dt;
            //绑定每列的显示字段
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEcode";
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEname";
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEunit";
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEliang";
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEprice";
            YuSuanBiaoDGV.Columns[].DataPropertyName = "DEtotal";
            YuSuanBiaoDGV.Columns[].ReadOnly = false;

2. ListView显示自定义表

 //造组,添加组
            ListViewGroup ls = new ListViewGroup();
            ls.Items.Add(buweiname);
            ls.Tag = buweicode;
            ls.Header = buweiname;
            YuSuanBiao.Groups.Add(ls);

            //小状态栏
            GcbuweiState.Text = "当前工程部位：" + buweiname;

            //添加进预算表
            ListViewItem item = new ListViewItem();
            item.Text = "部位";
            item.Tag = buweicode;
            item.Group = ls;
            item.BackColor = Color.LightPink;

            ListViewItem.ListViewSubItem dename = new ListViewItem.ListViewSubItem();
            dename.Text = buweiname;
            item.SubItems.Add(dename);

            item.SubItems.Add("处");

            ListViewItem.ListViewSubItem count = new ListViewItem.ListViewSubItem();
            count.Text = "";
            item.SubItems.Add(count);

            ListViewItem.ListViewSubItem jiage = new ListViewItem.ListViewSubItem();
            double jia = PartTotalPrice(GCname.Tag.ToString(), buweicode);
            jiage.Text = jia.ToString();
            item.SubItems.Add(jiage);

            ListViewItem.ListViewSubItem zongjia = new ListViewItem.ListViewSubItem();
            double zongjiage = Convert.ToDouble(count.Text) * Convert.ToDouble(jiage.Text);
            zongjia.Text = zongjiage.ToString();
            item.SubItems.Add(zongjia);

            YuSuanBiao.Items.Add(item);

3. 修改DataGridView的列名显示：

            string[] Htxt = { "定额号", "成本价", "定额名称", "定额单位代号", "档次代号", "工艺做法", "类型代号", "价格" };
            for (int i = ; i < DExiangxiDGV.Columns.Count; i++)
            {
                DExiangxiDGV.Columns[i].HeaderText = Htxt[i];
            }
