篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Devexpress使用之:GridControl控件相关的知识,希望对你有一定的参考价值。
Devexpress系列控件功能很强大,使用起来也不太容易,我也是边摸索边使用,如果有时间我会把常用控件的使用方法整理出来的。
using System; using System.Collections.Generic; using System.ComponentModel; using System.Windows.Forms; using DevExpress.XtraGrid.Columns; using DevExpress.XtraGrid.Views.Base; using DevExpress.XtraGrid.Views.BandedGrid;

} ///初始化表格 private void InitGrid() { // advBandedGridView1是表格上的默认视图,注意这里声明的是:BandedGridView BandedGridView view = advBandedGridView1 as BandedGridView; view.BeginUpdate(); //开始视图的编辑,防止触发其他事件 view.BeginDataUpdate();
