GridView控件用來在表中顯示資料源中的值.. GridView控件可用于任何重複的結構中的資料.
控件支援以下功能:
1:可綁定資料源控件;
2:内置排序功能;
3:内置更新和删除功能;
4:内置行選擇功能;
5:用于超連結列的多個資料字段;
6:可通過主題和樣式進行自定義外觀;
首先建立資料實體層MessageType
using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
namespace JingXin.Model
{
public class MessageType
{
private int _M_Id;
public int M_Id
{
get { return _M_Id; }
set { _M_Id = value; }
}
private string _M_Name;
public string M_Name
get { return _M_Name; }
set { _M_Name = value; }
}
}
建立資料庫連接配接: help
using System.Data.SqlClient;
namespace JingXin.DAL
public class Help
private SqlConnection conn = null;
private SqlCommand com = null;
private string sqlconnection = "Data Source=.;Initial Catalog=JingXin;User ID=sa;Password=sa";
public Help()
conn = new SqlConnection(sqlconnection);
com = new SqlCommand();
com.Connection = conn;
public int ExeNo(string sql, System.Data.CommandType ct)
int fh;
com.CommandText = sql;
com.CommandType = ct;
conn.Open();
fh = com.ExecuteNonQuery();
conn.Close();
return fh;
public System.Data.DataTable ExeTable(string sql,CommandType ct)
System.Data.DataTable dt = new System.Data.DataTable();
SqlDataAdapter oda = new SqlDataAdapter(com);
oda.Fill(dt);
return dt;
建立方法類MessageTypeDAL
public class MessageTypeDAL:Help
private Model.MessageType Mt;
public MessageTypeDAL()
{ }
public MessageTypeDAL(Model.MessageType mt)
this.Mt = mt;
public int Update()
string sql = " UPDATE [MessageType] SET M_Name='" + Mt.M_Name + "' WHERE M_Id = " + Mt.M_Id + " ";
return ExeNo(sql, CommandType.Text);
public int Delete()
string sql = " DELETE FROM [MessageType] WHERE M_Id = " + Mt.M_Id + " ";
public DataTable Select()
string sql = " SELECT * FROM [MessageType] ";
return ExeTable(sql, CommandType.Text);
建立頁面
MessageTypeManage.aspx
從工具中資料拖取GridView控件
在GridView中實作顯示資料
1、編輯GridView的頁眉模闆
2、編輯GridView的項模闆（itemtemplete）
3、寫方法，在一個類中将要顯示的資料庫表中所有資料
添加到記憶體的一個DataTable裡
4、在頁面的load事件裡加載資料，注意需要設定GridView的datasource屬性和調用GridView的databind（）方法
5、在itemtemplete中将資料庫表中的字段綁定到指定的label上去，注意綁定的方法，調用Eval（）
在GridView中實作删除資料
1、在項模闆中添加一列，放入linkbutton，并且将該linkButton的CommandName屬性設定為delete
2、調用GridView的DeleteCommand事件，在該事件中實作删除
3、通過事件的參數e來擷取選中行的索引值，根據該索引值在GridView中findControl你指定的控件
4、去資料庫删除（即調用删除方法），重新整理本頁面
在GridView中實作編輯
1、編輯editItemTemplete，注意主鍵列不能使用textBox
2、将頁面編輯按鈕的CommandName屬性設定為edit
3、在GridView的EditCommand事件中将目前選中行指派給GridView的EditItemIndex屬性
4、重新整理本頁面
在GridView中實作更新
1、将編輯模闆的更新按鈕的CommandName屬性設定為update
2、寫更新的方法
3、在GridView的UpdateCommand事件中擷取編輯模闆中各個項的具體值，然後調用方法修改資料庫
4、将目前編輯項的索引值改為-1，重新整理本頁面
完成後頁面代碼:
