浅谈dataGridView使用，以及画面布局使用属性，对datagridview进行增删改查操作，以及委托使用技巧
通过几天的努力后，对datagridview使用作一些简要的介绍，该实例主要运用与通过对datagridview操作。对数据进行增删改查操作时，进行逻辑判断执行相关操作。简单的使用委托功能，实现子画面数据更新操作后，主画面也执行相关的刷新操作，达到数据实时跟新。另外对界面的布局花了点功夫，给予视觉感受稍微好点。话不多少，随小编进入实际练习的环节。
开发环境
开发工具：Microsoft Visual Studio 旗舰版、SQL Server 2008.
开发环境：.NET Framework 4 Client Profile.
实现步骤
1、采用MVC思想建立框架、建立PERSON_T表格；
首先，了解什么是MVC框架,MVC全名是Model View Controller，是模型(model)－视图(view)－控制器(controller)的缩写，一种软件设计典范，用于组织代码用一种业务逻辑和数据显示分离的方法，这个方法的假设前提是如果业务逻辑被聚集到一个部件里面，而且界面和用户围绕数据的交互能被改进和个性化定制而不需要重新编写业务逻辑MVC被独特的发展起来用于映射传统的输入、处理和输出功能在一个逻辑的图形化用户界面的结构中。
我在VS项目中建立一个目录如下图
然后，在SQL2008中FMSDB数据库中建立PERSON_T表;具体代码见下方：
1: USE [FMSDB]
2: GO
3:
4: /****** Object: Table [dbo].[PERSON_T] Script Date: 08/05/2013 22:40:39 ******/
5: SET ANSI_NULLS ON
6: GO
7:
8: SET QUOTED_IDENTIFIER ON
9: GO
10:
11: CREATE TABLE [dbo].[PERSON_T](
12: [ID] [nvarchar](50) NULL,
13: [NAME] [nvarchar](50) NULL,
14: [AGE] [int] NULL,
15: [POSITION] [nvarchar](50) NULL,
16: [HOMEADDRESS] [nvarchar](50) NULL,
17: [IDENTIFYNUMBER] [nvarchar](50) NULL
18: ) ON [PRIMARY]
19:
20: GO
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
2、视图层设置属性
MaximizeBox 设置为false 去除最大化窗口
MinimizeBox 设置为false 去除最小化窗口
StarPosition 设置为CenterScreen 画面启动居中
主画面lable居中采用 TextAlign设置为 MiddleCenter
主画面datagridview靠下 将Dock设置为 Bottom
其余见最下面源码下载
具体运行效果图见下方

运行效果图
主画面效果图，主要分查询、增加、修改、删除功能，另外下方显示用户信息。
查询分为姓名或身份证号查询用户信息
点击edit按钮后跳出界面如下所示，带出选中datagridview那行信息，进行更新操作。
按确认完成更新操作
点击Add按钮后跳出界面如下所示，插入数据界面
若添加数据与已有数据重复会有提示，具体见下图
在datagridview中右键后跳出确定/取消，删除选中用户信息后界面，删除用户后主画面更新
技术点
1、子画面进行用户的增加或修改成功后，主画面datagridview也会有相应变动，采用委托功能。
2、contextMenuStrip1与datagridview绑定，右击实现删除功能；
3、界面布局相应属性设置，使界面美观。
4、牢记面向对象的编程思想，创建对象，实例化对象。
疑难点
1、熟练使用listbox、dateset、dategridview中数据之间的传递和赋值
2、委托方法使用加强锻炼，灵活运用到实际项目中，提高程序稳定性
感受
本人通过这个小实例练习过后，已经对于面向对象编程有了一定的熟悉，由于基础知识欠佳，对于某些赋值处理过程不是很熟练，从而花费大量时间查阅资料。想要快速完成代码，还得从基础下手，理解编程思想，多练多看多问，才能迅速提升编程能力。总之，合理利用时间，有效利用资源。我相信，you are best!
