dev GirdView自动筛选行，如何实现多选？

[NotNull]

如题，
并不是使用它


但是最终筛选效果是一样

[NotNull]

gridControl有一个过滤功能 https://documentation.devexpress.com/#WindowsForms/CustomDocument3014

[zijiang001]

void gridView1_CustomRowCellEdit(object sender, CustomRowCellEditEventArgs e) { if (e.RowHandle == GridControl.AutoFilterRowHandle) { e.RepositoryItem = repositoryItemCheckedComboBoxEdit1; } } 只是这样要重写筛选规则
