一、首先要将gridview设置成可以分页，然后我们在增加如下代码：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="98%" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" PageSize="20"> <Columns> <asp:BoundField DataField="UserName" HeaderText="登陆用户名" > <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:BoundField DataField="Name" HeaderText="真实姓名"> <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:BoundField DataField="PostName" HeaderText="职位" > <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:BoundField DataField="OrgName" HeaderText="组织" > <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:BoundField DataField="RoleName" HeaderText="角色" > <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:BoundField DataField="StateStr" HeaderText="当前状态" > <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:BoundField> <asp:TemplateField HeaderText="操作"> <ItemTemplate> <asp:LinkButton ID="LinkButtonEdit" runat="server" CommandArgument='<%# Eval("UserID") %>' OnClick="LinkButtonEdit_Click">编辑</asp:LinkButton> <asp:LinkButton ID="LinkButtonDelete" runat="server" CommandArgument='<%# Eval("UserID") %>' OnClick="LinkButtonDelete_Click">删除</asp:LinkButton> </ItemTemplate> <ItemStyle CssClass="griditem" /> <HeaderStyle CssClass="gridhead" /> </asp:TemplateField> </Columns> <EmptyDataTemplate> <table border='0' cellpadding='0' cellspacing='0' style='border-right: coral 1px dotted;border-top: coral 1px dotted; border-left: coral 1px dotted; border-bottom: coral 1px dotted;background-color: #ffffff;200px;height:55px;'><tr><td align='center' style="height: 53px"><font color='coral'><b>没有任何数据<b></font></B></B></td></tr></table> </EmptyDataTemplate> <PagerTemplate> <table border="0" cellpadding="0" cellspacing="0" style=" 99%; height: 15px"> <tr> <td style=" 100px; height: 13px"> </td> <td style=" 100px; height: 13px"> <div style=" 286px; height: 7px; font-size:12px;"> 总共 <%=RecordCount%> 条记录 当前第 <%#((GridView)Container.NamingContainer).PageIndex+1%>/<%#((GridView)Container.NamingContainer).PageCount %> 页 </div> </td> <td style=" 100px; height: 13px"> <div style=" 252px; height: 8px; text-align: right"> <asp:LinkButton ID="FirstPage" runat="server" CommandArgument="First" CommandName="Page" Enable="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">第一页</asp:LinkButton> <asp:LinkButton ID="PreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" Enable="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton> <asp:LinkButton ID="NextPage" runat="server" CommandArgument="Next" CommandName="Page" Enable="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton> <asp:LinkButton ID="LastPage" runat="server" CommandArgument="Last" CommandName="Page" Enable="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">最后一页</asp:LinkButton> <asp:TextBox ID="TextGotoPage" runat="server" CssClass="pageeditbox"></asp:TextBox> <asp:Button ID="PageGo" causesvalidation="False" commandargument="-1" commandname="Page" runat="server" CssClass="pagebutton" Text="Go" /> </div> </td> <td style=" 100px; height: 13px"> <div style=" 266px; height: 1px"> </div> </td> </tr> </table> </PagerTemplate> </asp:GridView>红色的部分就是自定义的分页代码，其实LinkButton里的CommandArgument参数就是gridview的当前页，CommandName表示触发的命令，这些都不能改。
注意里面有个RecordCount的变量，他是public类型，是从后台传过来的，表示记录的条数，测试的时候别忘了这个变量啊。
二、分页的代码
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
SetGridPage(sender, e,DtSource)
}SetGridPage的函数
/// <summary> /// 分页处理 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> /// <param name="dt"></param> public void SetGridPage(object sender, GridViewPageEventArgs e,DataTable dt) { GridView theGrid = (GridView)sender; // refer to the GridView int newPageIndex = 0; GridViewRow pagerRow = theGrid.BottomPagerRow; //GridViewRow pagerRow = theGrid.Controls[0].Controls[theGrid.Controls[0].Controls.Count - 1] as GridViewRow; // refer to PagerTemplate //GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了HeaderRow和FooterRow if (-2 == e.NewPageIndex)//点击按钮的事件
{ 
TextBox txtNewPageIndex = null; if (null != pagerRow) { txtNewPageIndex = (TextBox)pagerRow.FindControl("TextGotoPage"); // refer to the TextBox with the NewPageIndex value
} if (null != txtNewPageIndex && txtNewPageIndex .Text !="") { newPageIndex = int.Parse(txtNewPageIndex.Text) - 1; // get the NewPageIndex } else { newPageIndex = 0; } } else { //当点击分页连接的时候 newPageIndex = e.NewPageIndex; } // 处理超出范围的分页 newPageIndex = newPageIndex < 0 ? 0 : newPageIndex; newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex; ((TextBox)pagerRow.FindControl("TextGotoPage")).Text = Convert.ToString(newPageIndex + 1); //帮定数据源 theGrid.PageIndex = newPageIndex; theGrid.DataSource = dt; theGrid.DataBind();
}
