c# - 带有 checkBoxEdit 列的 DevExpress XtraGrid 控件

Question

我有一个 DevExpress XtraGrid控件具有三列和一个未绑定(bind)的 checkBoxEdit 列，供用户在从网格中删除项目时进行选择。我能够在 xtraGrid 上添加 checkBoxEdit。但是，我不知道如何删除选定列表的主键。任何想法都受到高度赞赏。谢谢

我相信你可以使用以下方法:

void InitGrid() {
    gridControl1.DataSource = new List<Person> { 
        new Person(){ ID = 0 }, 
        new Person(){ ID = 1 }, 
        new Person(){ ID = 2 }
    };
    gridView.Columns["ID"].Visible = false;
    gridView.Columns.Add(new DevExpress.XtraGrid.Columns.GridColumn()
    {
        UnboundType = DevExpress.Data.UnboundColumnType.Boolean,
        Caption = "Mark as Deleted",
        FieldName = "IsDeleted",
        Visible = true,
    });
}
IDictionary<int, object> selectedRows = new Dictionary<int, object>();
void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e) {
    int id = (int)gridView.GetListSourceRowCellValue(e.ListSourceRowIndex, gridView.Columns["ID"]);
    if(e.IsGetData) 
        e.Value = selectedRows.ContainsKey(id);
    else {
        if(!(bool)e.Value)
            selectedRows.Remove(id);
        else selectedRows.Add(id, e.Row);
    }
}
void OnDelete(object sender, System.EventArgs e) {
    //... Here you can iterate thought selectedRows dictionary
}
//
class Person {
    public int ID { get; set; }
    public string Name { get; set; }
    public string Age { get; set; }
}
