怎家DataList控件为其配置数据好数据源
增加四个LinkButton 控件
分别为：
<asp:LinkButton ID="linkbtnFirst" runat="server" onclick="labFirst_Click">首页</asp:LinkButton>
<asp:LinkButton ID="linkbtnFont" runat="server" onclick="labFont_Click">上一页</asp:LinkButton>
<asp:LinkButton ID="linkbtnNext" runat="server" onclick="labNext_Click">下一页</asp:LinkButton>
<asp:LinkButton ID="linkbtnLast" runat="server" onclick="labLast_Click">最后一页</asp:LinkButton>
在加两个了Label控件
分别为：
当前页数:[<asp:Label ID="labpage" runat="server" Text="1"></asp:Label>]
总页数:[<asp:Label ID="labBackPage" runat="server" Text=""></asp:Label>]
在Default.aspx.cs文件中
自定义Mind（）方法
//------------------------------------------------------------
protected void Page_Load(object sender EnventArgs e)
{
if (!IsPostBack)
{
Mind();
}
}Private void Mind()
{
//获得当前页数
int curpage= Convert.toInt32(this.labPage.Text);
// 生成PageDataSource实例
PageDataSource ps= new PageDataSource();
SqlConnection con= new SqlConnection("连接字符串");
SqlDataAdapter sda= new SqlDataAdapter(("select *from BookInfo",con);
DataSet ds = new DataSet();
sda.Fill(da,"BooKInfo");
//获取数据源
ps.DataSource=da.DataTables["BookInfo"].DefaultView;
ps.AllowPaging= true;
ps.PageSize= 3;
ps.CurrentPageIndex=curpage-1;
this.linkbtnFirst.Enabled=true;
this.linkbtnFont.Enabled=true;
this.linkbtnNext.Enabled=true;
this.linkbtnLast.Enabled=true;
if(curpage==1)
{
this.linkbtnFirst.Enabled=false;
this.linkbtnFont.Enabled= false;
}
if(crupage==ps.PageCount)
{
this.linkbtnLast.Enabled= false;
this.linkbtnNext.Enabled= false;
}
this.labBackPage=Convert.ToInt32(ps.PageCount);
this.DataList1.DataSource= ps;
this.DataList1.DatakeyField="ID";
DataList1.DataSource=ps;
con.Close();
}
protected void linkbtnFirst_Click(object sender, EventArgs e)
{
labpage.Text = "1";
Mind();
}
protected void linkbtnFont_Click(object sender, EventArgs e)
{
labpage.Text = Convert.ToString (Convert.ToInt32(labpage.Text) - 1);
Mind();
}
protected void linkbtnNext_Click(object sender, EventArgs e)
{
labpage.Text = Convert.ToString(Convert.ToInt32(labpage.Text) + 1);
Mind();
}
protected void linkbtnLast_Click(object sender, EventArgs e)
{
labpage.Text = labBackPage.Text;
Mind();
}
