DevExpress XtraGrid控件与checkBoxEdit列 [英] DevExpress XtraGrid Control with checkBoxEdit column

问题描述

我有一个DevExpress XtraGrid 控件，带有三列和未绑定checkBoxEdit列，供用户从网格中删除项目时选择。我可以在xtraGrid上添加checkBoxEdit。但是，我没有任何想法，我可以如何获取所选列表的主键被删除。任何想法都非常感激。谢谢

I've a DevExpress XtraGrid control with three columns and a unbound checkBoxEdit column for users to select when deleting items from the grid. I'm able to add the checkBoxEdit on the xtraGrid. However, i don't have any idea as to how i can get the selected lists' primary key(s) to be deleted. Any idea is highly appreciated. Thanks

推荐答案

我相信可以使用以下方法：

I believe you can use the following approach:

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; }
}
