AspNetPager的使用实例说明

1、添加引用

2、在页面上拖放控件

3、

<%@ Register assembly="AspNetPager" namespace="Wuqi.Webdiyer" tagprefix="webdiyer" %>

 

4、控件的基本属性设置

<webdiyer:AspNetPager ID="AspNetPager1"   runat="server" 

           FirstPageText='首页'

        LastPageText='尾页'  PagingButtonSpacing="10px" ShowPageIndexBox="Always" CustomInfoHTML="共%RecordCount%条，第%CurrentPageIndex%页 /共%PageCount% 页"

                                 NextPageText="下一页" PrevPageText ="上一页"

                                 ShowCustomInfoSection="Left"

                                 SubmitButtonText ="Go" TextAfterPageIndexBox ="页" 

            TextBeforePageIndexBox ="转到 " UrlPaging="True" 

            CustomInfoSectionWidth="20%" CustomInfoTextAlign="Center" 

            onpagechanged="AspNetPager1_PageChanged">

        </webdiyer:AspNetPager>

 

5、后台代码

protected void Page_Load(object sender, EventArgs e)

    {

         string sqlStr = "select * from download  where 1=1 ";

        if (key.Text != "")

        {

            sqlStr += "and title like '%" + key.Text + "%' order by id desc";

 

        }

        else

        {

            sqlStr += "order by id desc";

        }

        string s = ConfigurationManager.ConnectionStrings["siteconn"].ConnectionString;            //定义连接字符串

        SqlConnection conn = new SqlConnection(s);  //新建数据库连接对象，其中s是上面的连接字符串

        conn.Open();    //打开与数据库的连接

        SqlCommand cmd = new SqlCommand(sqlStr, conn);

        AspNetPager1.AlwaysShow = true;

        AspNetPager1.PageSize = 15;

        AspNetPager1.RecordCount = (int)cmd.ExecuteScalar();

        conn.Close();

        bind();

       

       }

    private void bind()

    {

        string sqlStr = "select * from download  where 1=1 ";

        if (key.Text != "")

        {

            sqlStr += "and title like '%" + key.Text + "%' order by id desc";

 

        }

        else

        {

            sqlStr += "order by id desc";

        }

        string s = ConfigurationManager.ConnectionStrings["siteconn"].ConnectionString;            //定义连接字符串

        SqlConnection conn = new SqlConnection(s);  //新建数据库连接对象，其中s是上面的连接字符串

        conn.Open();    //打开与数据库的连接

        DataSet myds = new DataSet();

        SqlDataAdapter adapter = new SqlDataAdapter(sqlStr, conn);

        adapter.Fill(myds, AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex - 1), AspNetPager1.PageSize, "myds");

        GridView1.DataSource = myds.Tables["myds"];

        GridView1.DataBind(); 

    }

   

    protected void AspNetPager1_PageChanged(object sender, EventArgs e)

    {

        bind();

    }

 

6、添加序号

 <asp:TemplateField HeaderText="序号"> 

<ItemTemplate> 

<%# (this.AspNetPager1.CurrentPageIndex - 1) * this.AspNetPager1.PageSize + Container.DataItemIndex + 1%> 

</ItemTemplate> 

</asp:TemplateField>
