(C#) ASP.NET GridView Control - AllowSorting and AllowPaging |
(C#) ASP.NET GridView Control - AllowSorting and AllowPaging ตัวอย่างนี้ผมได้ยากตัวอย่างการใช้ GridView เพื่อทำการแบ่งหน้าและโหมดในส่วนของการจัดเรียงพร้อมๆ กัน
Language Code : VB.NET ||  C#
Framework : 2,3,4
GridViewAllowSortingAllowPaging.aspx
<%@ Page Language="C#" Debug="true" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<script runat="server">
String strFields = "CustomerID";
void Page_Load(object sender,EventArgs e)
{
if(!Page.IsPostBack)
{
BindData();
}
}
void BindData()
{
OleDbConnection objConn = new OleDbConnection();
OleDbCommand objCmd = new OleDbCommand();
OleDbDataAdapter dtAdapter = new OleDbDataAdapter();
DataSet ds = new DataSet();
String strConnString,strSQL;

Server.MapPath("database/mydatabase.mdb") + ";";
strSQL = "SELECT * FROM customer ORDER BY " + strFields + " ASC";
objConn.ConnectionString = strConnString;
objCmd.Connection = objConn;
objCmd.CommandText = strSQL;
objCmd.CommandType = CommandType.Text;
dtAdapter.SelectCommand = objCmd;
dtAdapter.Fill(ds);
//*** BindData to GridView ***//
myGridView.DataSource = ds;
myGridView.DataBind();
dtAdapter = null;
objConn.Close();
objConn = null;
}
void ShowPageCommand(Object s, GridViewPageEventArgs e)
{
myGridView.PageIndex = e.NewPageIndex;
BindData();
}
void SortCommand(Object s, GridViewSortEventArgs e)
{
strFields = e.SortExpression;
BindData();
}
void myGridView_RowDataBound(Object s, GridViewRowEventArgs e)
{
//*** CustomerID ***//
Label lblCustomerID = (Label)(e.Row.FindControl("lblCustomerID"));
