如何使用Linq在C＃Winforms中使用.Databind方法 [英] How Do I Use .Databind Method In C# Winforms Using Linq

问题描述

Hello House，



我有一个C＃winform，我使用linq从数据库中检索记录，如果用户点击一条记录，表格会显示在showdialog上填充记录信息的文本框，决定删除或更新记录，以及创建新记录的链接，我希望能够在gridview上显示新记录或更新的记录，或者已删除角色而未关闭主窗体。有没有我能做到的？



i试过这个：

Hello House,

I have a C# winform, i am using linq to retrieve record from database, if a user clicks on a record, a form is shown on showdialog that populates that record information on a textbox, which the decides either to delete or update the record, and also a link to create new record, i want to be able show on the gridview the new record, or the updated record, or that a role has been deleted without closing the main form. Is there anywhere i can achieve this?

i have tried this:

var dbEntities = new NewSchoolCoreEntities( );
            var BindingSource = from a in dbEntities.devices 
                                select new {
                                    IdDevice = a.id,
                                    DeviceType = a.device_type_name,
                                    DeviceName = a.device_name,
                                    ModelNumber = a.model_number ,
                                    MacAddress = a.mac_address,
                                    IsActive = a.device_active,
                                    IsInUse = a.in_use 
                                };
            var bindingSource = new BindingSource( );
            bindingSource.DataSource = BindingSource.ToList();
            dataGridView1.DataSource=bindingSource;

但不工作！任何贡献将不胜感激。谢谢。
