前人栽树,后人乘凉,话不多说,代码如下:
实现方式一:
.aspx:
[c-sharp] view plain copy
- <form id="form1" runat="server">
- <table style="width: 605px">
- <tr>
- <td style="width: 921px">
- <asp:GridView ID="GridView1" runat="server" Width="700px" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" Height="232px">
- <PagerSettings Visible="False" />
- </asp:GridView>
- </td>
- </tr>
- <tr>
- <td style="width: 921px; height: 23px" >共
- <asp:Label ID="recordCount" runat="server"></asp:Label> 条/
- <asp:Label ID="LabelCurrentPage" runat="server"></asp:Label>
- <asp:Label ID="LabelPageCount" runat="server"></asp:Label>页
- <asp:LinkButton ID="First" runat="server" CommandArgument="First" CommandName="Page" OnClick="PagerButton_Click">首页</asp:LinkButton>
- <asp:LinkButton ID="Prev" runat="server" CommandArgument="Prev" CommandName="Page" OnClick="PagerButton_Click">上一页</asp:LinkButton>
- <asp:LinkButton ID="Next" runat="server" CommandArgument="Next" CommandName="Page" OnClick="PagerButton_Click">下一页</asp:LinkButton>
- <asp:LinkButton ID="Last" runat="server" CommandArgument="Last" CommandName="Page" OnClick="PagerButton_Click">尾页</asp:LinkButton>
- <asp:Label ID="Label1" runat="server">第</asp:Label>
- <asp:TextBox ID="txtPage" runat="server" Width="18px"></asp:TextBox>
- <asp:Label ID="Label2" runat="server">页</asp:Label>
- <asp:Button ID="btnLoginPage" runat="server" Text="GO" OnClick="btnLoginPage_Click" />
- </td>
- </tr>
- </table>
- </form>
.CS:(以下代码可能折叠,请自行点击下面的按钮展开)
[c-sharp] view plain copy
- using System;
- using System.Data;
- using System.Data.SqlClient;
- using System.Configuration;
- using System.Web;
- using System.Web.Security;
- using System.Web.UI;
- using System.Web.UI.WebControls;
- using System.Web.UI.WebControls.WebParts;
- using System.Web.UI.HtmlControls;
- public partial class _Default : System.Web.UI.Page
- {
- protected void Page_Load(object sender, EventArgs e)
- {
- if (!this.IsPostBack)
- {
- //绑定数据
- Bind();
- }
- //计算生成分页页码
- this.First.CommandName = "1";
- this.Prev.CommandName = this.GridView1.PageIndex == 0 ? "1" : this.GridView1.PageIndex.ToString();
- if (this.GridView1.PageCount == 1)
- {
- this.Next.CommandName = this.GridView1.PageCount.ToString();
- }
- else
- {
- int temp = this.GridView1.PageIndex + 2;
- this.Next.CommandName = temp.ToString();
- }
- this.Last.CommandName = this.GridView1.PageCount.ToString();
- }
- protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
- {
- GridView1.PageIndex = e.NewPageIndex;
- this.Bind();
- }
- //点击LinkButton按钮事件
- protected void PagerButton_Click(object sender, EventArgs e)
- {
- this.GridView1.PageIndex = Convert.ToInt32(((LinkButton)sender).CommandName) - 1;
- this.Bind();
- }
- protected void Bind()
- {
- //数据绑定代码
- string strconn = "Data Source=.; Initial Catalog=JWInfo; uid=sa;pwd=123456;";
- SqlConnection conn = new SqlConnection(strconn);
- conn.Open();
- SqlCommand cmd = new SqlCommand("select * from 学生信息", conn);
- SqlDataAdapter sda = new SqlDataAdapter();
- sda.SelectCommand = cmd;
- DataSet ds = new DataSet();
- sda.Fill(ds, "学生信息");
- GridView1.DataSource = ds.Tables["学生信息"];
- GridView1.DataBind();
- //总页数,当前页,总记录数
- this.recordCount.Text = ds.Tables[0].Rows.Count.ToString();
- int t = this.GridView1.PageIndex+1;
- this.LabelCurrentPage.Text = t.ToString();
- this.LabelPageCount.Text = this.GridView1.PageCount.ToString();
- //设置相关按钮是否可见
- this.First.Enabled = Convert.ToBoolean(GridView1.PageIndex != 0);
- this.Prev.Enabled = Convert.ToBoolean(GridView1.PageIndex != 0);
- this.Next.Enabled = Convert.ToBoolean(this.GridView1.PageIndex != this.GridView1.PageCount - 1);
- this.Last.Enabled = Convert.ToBoolean(this.GridView1.PageIndex != this.GridView1.PageCount - 1);
- }
- //页码跳转实现
- protected void btnLoginPage_Click(object sender, EventArgs e)
- {
- int page = Convert.ToInt32(txtPage.Text.Trim());
- if (page < 0 || page > GridView1.PageCount)
- {
- Response.Write("<mce:script language='javascript'><!--
- alert('输入的页码有错请重新输入');
- // --></mce:script>");
- }
- else
- {
- GridView1.PageIndex = page - 1;
- this.Bind();
- }
- }
- }
实现方式二:
这里通过使用GridView自带的分页模板实现,代码如下:
[c-sharp] view plain copy
- <form id="form1" runat="server">
- <div>
- <asp:GridView ID="GridView1" runat="server" Width="740px" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
- <PagerTemplate>
- <asp:Label ID="Label1" runat="server" Text="第"></asp:Label>
- <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
- <asp:Label ID="Label2" runat="server" Text="页"></asp:Label>
- <asp:Label ID="Label3" runat="server" Text="共"></asp:Label>
- <asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
- <asp:Label ID="Label4" runat="server" Text="页"></asp:Label>
- <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
- </PagerTemplate>
- </asp:GridView>
- </div>
- </form>
这其中,我曾看到有人,用类似的方法实现,但我在以下的代码中实现了一点小变动,将其中的Visable属性,改用Enable属性,本人认为更为合理,并且有利布局:
[c-sharp] view plain copy
- <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
- <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
.CS:
[c-sharp] view plain copy
- using System;
- using System.Data;
- using System.Data.SqlClient;
- using System.Configuration;
- using System.Web;
- using System.Web.Security;
- using System.Web.UI;
- using System.Web.UI.WebControls;
- using System.Web.UI.WebControls.WebParts;
- using System.Web.UI.HtmlControls;
- public partial class _Default : System.Web.UI.Page
- {
- protected void Page_Load(object sender, EventArgs e)
- {
- if (!this.IsPostBack)
- {
- Bind();
- }
- }
- protected void Bind()
- {
- string strconn = "Data Source=.; Initial Catalog=JWInfo; uid=sa;pwd=123456;";
- SqlConnection conn = new SqlConnection(strconn);
- conn.Open();
- SqlCommand cmd = new SqlCommand("select * from 学生信息", conn);
- SqlDataAdapter sda = new SqlDataAdapter();
- sda.SelectCommand = cmd;
- DataSet ds = new DataSet();
- sda.Fill(ds, "学生信息");
- GridView1.DataSource = ds.Tables["学生信息"];
- GridView1.DataBind();
- }
- protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
- {
- this.GridView1.PageIndex = e.NewPageIndex;
- this.Bind();
- }
- }
以上是对别人实现的一些总结,和对其中一些代码实现的改进,希望各位指教!
