DevExpress GridControl功能总结

 bandedGridView1.Appearance.OddRow.BackColor = Color.White; // 设置奇数行颜色 // 默认也是白色 可以省略 
            bandedGridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面绑定 同时使用有效 
            bandedGridView1.Appearance.EvenRow.BackColor = Color.FromArgb(255, 250, 205); // 设置偶数行颜色 
            bandedGridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面绑定 同时使用有效
            if (e.RowHandle == bandedGridView1.FocusedRowHandle)
            {
                e.Appearance.Font = new Font("宋体", 9, FontStyle.Bold);
            }
