1、效果如下 2、设置 gridView1.OptionsCustomization.AllowFilter = true;                      //是否允许过滤 gridView1.IndicatorWidth = 40;                       //行标题高度 gridView1.OptionsView.ShowIndicator = true;          // 显示行标题 注册写行号事件  gridView1.CustomDrawRowIndicator += new DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(gridView1_CustomDrawRowIndicator);   private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) { e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; //行号对齐方式 if (e.RowHandle == GridControl.AutoFilterRowHandle) { e.Info.DisplayText = "筛选行"; //筛选行加行标题 } if (e.Info.IsRowIndicator && e.RowHandle >= 0) { e.Info.DisplayText = (e.RowHandle +1).ToString() ; //行号 } }       3、修改默认筛选条件   if (list.Count > 20) //大于20行时，显示筛选行 { gridView1.OptionsView.ShowAutoFilterRow = true; foreach (DevExpress.XtraGrid.Columns.GridColumn item in gridView1.Columns) { item.OptionsFilter.AutoFilterCondition = DevExpress.XtraGrid.Columns.AutoFilterCondition.Contains; //筛选条件设置为包含 } }
