DevExpress控件GridView使用方法记录

gridView水平滚动条:

this.gridView1.OptionsView.ColumnAutoWidth = false;//自动列宽无效,同时出现水平滚动条

gridView显示行号,gridView的CustomDrawRowIndicator事件中处理,把IndicatorWidth设置一个宽度,也可在Load事件中加入this.gridView1.IndicatorWidth = 65;

//也可在Load事件中加入this.gridView1.IndicatorWidth = 65;
private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
            if (e.Info.IsRowIndicator)
            {
                if (e.RowHandle >= 0)
                {
                    e.Info.DisplayText = (e.RowHandle + 1).ToString();
                }
                else if (e.RowHandle < 0 && e.RowHandle > -1000)
                {
                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                    e.Info.DisplayText = "G" + e.RowHandle.ToString();
                }
            }
        }

GridControl.DataSouce = dt;绑定数据表后在GridView表中不显示数据

string sql = string.Format("select * from tb_Details where ID='{0}'",ID);

            dt = SqlHelper.ExecuteReader(SqlHelper.ConnStr, CommandType.Text, sql);
            this.gridControl1.DataSource = dt.DefaultView;
            this.gridControl1.RefreshDataSource();//加上这句就显示出来了

持续更新记录中....
